Vulnerability / Mobile Network

A collection of security flaws in the firmware implementation of 5G mobile network modems from major chipset vendors such as MediaTek and Qualcomm impact USB and IoT modems as well as hundreds of smartphone models running Android and iOS.

Of the 14 flaws – collectively called **5Ghoul** (a combination of "5G" and "Ghoul") – 10 affect 5G modems from the two companies, out of which three have been classified as high-severity vulnerabilities.

"5Ghoul vulnerabilities may be exploited to continuously launch attacks to drop the connections, freeze the connection that involve manual reboot or downgrade the 5G connectivity to 4G," the researchers said in a study published today.

As many as 714 smartphones from 24 brands are impacted, including those from Vivo, Xiaomi, OPPO, Samsung, Honor, Motorola, realme, OnePlus, Huawei, ZTE, Asus, Sony, Meizu, Nokia, Apple, and Google.

The vulnerabilities were disclosed by a team of researchers from the ASSET (Automated Systems SEcuriTy) Research Group at the Singapore University of Technology and Design (SUTD), who also previously disclosed BrakTooth in September 2021 and SweynTooth in February 2020.

The attacks, in a nutshell, attempt to deceive a smartphone or a 5G-enabled device to connect a rogue base station (gNB), resulting in unintended consequences.

"The attacker does not need to be aware of any secret information of the target UE e.g., UE's SIM card details, to complete the NAS network registration," the researchers explained. "The attacker only needs to impersonate the legitimate gNB using the known Cell Tower connection parameters."

A threat actor can accomplish this by using apps like Cellular-Pro to determine the Relative Signal Strength Indicator (RSSI) readings and trick the user equipment to connect to the adversarial station (i.e., a software-defined radio) as well as an inexpensive mini PC.

Notable among the 14 flaws is CVE-2023-33042, which can permit an attacker within radio range to trigger a 5G connectivity downgrade or a denial-of-service (DoS) within Qualcomm's X55/X60 modem firmware by sending malformed Radio Resource Control (RRC) frame to the target 5G device from a nearby malicious gNB.

Successful exploitation of the other DoS vulnerabilities could require a manual reboot of the device to restore 5G connectivity.

Patches have been released by both MediaTek and Qualcomm for 12 of the 14 flaws. Details of the two other vulnerabilities have been withheld due to confidentiality reasons and are expected to be disclosed in the future.

"Finding issues in the implementation of the 5G modem vendor heavily impacts product vendors downstream," the researchers said, adding that "it can often take six or more months for 5G security patches to finally reach the end-user via an OTA update."

"This is because the software dependency of product vendors on the Modem / Chipset Vendor adds complexity and hence delays to the process of producing and distributing patches to the end-user."

New 5G Modems Flaws Affect iOS Devices and Android Models from Major Brands

When searching for holiday gifts online, make sure you’re buying from a trusted vendor, or if you haven’t heard of the vendor before, take a few extra minutes just to look them up and read their app’s privacy policy.

Thursday, December 7, 2023 14:00

As I wrote about last week, there are holiday shopping-related scams already popping up all over the place.  

But another aspect of security that many shoppers don’t consider this time of year is the security of the products they’re buying, even through a legitimate online marketplace. 

This is a glaring issue with home security cameras and Wi-Fi-connected doorbells, but I can’t imagine these are particularly popular holiday gifts. With virtually everything being connected to the internet somehow these days, everything is a potential security risk if you’re buying a new piece of technology. 

Take smartwatches, for example. Apple Watches and Samsung Galaxy watches are always popular on everyone’s wishlists this time of year because they’re high-priced items you normally wouldn’t buy for yourself. Many shoppers might be looking for a deal this time of year and not looking to spend hundreds on the gift, so any sort of cheaper alternative could be appealing. 

I searched for “smart watches” on Amazon, and the results page displayed four different watches from four different vendors as their “Top Results,” none of which were Samsung and Apple. Well-known vendors are certainly not immune to security issues or vulnerabilities, but at least users can be confident that any known vulnerabilities will be disclosed and patched by these companies as they pop up. 

The top result is for a $29.99 smartwatch that offers sleep tracking, blood pressure monitoring, dozens of different workout modes, step tracking, and more. However, there are a few security flags for me right up front with this deal (after all, if it seems too good to be true, it probably is). Amazon states the seller is a company called “Nerunsa,” but a quick search did not turn up any legitimate information on who this company is, where they’re based, or the sort of security bona fides you’d be hoping for. The only search results are for the company’s Amazon store page and a few eBay listings for people reselling the watch in question. 

The app that’s listed as supporting the watch is called “GloryFit” on the Google Play and Apple app stores, and its privacy policy is equally vague. It states that the app will collect all the suspected information for someone using a smartwatch — phone calls, text messages, GPS location, personal information, health information, etc. But, the policy states that, when the user accepts the privacy policy, “You hereby consent to our process and disclose personal information to our affiliated companies (which are in the communications, social media, technology and cloud businesses) and to Third Party Service Providers for the purposes of this Privacy Policy.” And it’s not particularly clear what those other companies do, exactly — Google was no help here, either. 

Apple Air Tags are also another popular tech gift every year and are usually featured in major retailers’ Black Friday sales. I personally have my own concerns about any type of tracking tag coming into my house, but that’s for another column. 

On Walmart, which is increasingly trying to compete with Amazon by offering more products online, I searched for “smart tag” and found three results that appeared ahead of Apple’s legitimate Air Tags. The second-most-popular result is for a “Bluetooth Tracker and Item Locator” that’s only $15.98, compared to $86.88 for a four-pack of Apple’s. This tracker is listed as being made by “AILIUTOP,” which also remains elusive on the internet and does not seem to have any sort of legitimate contact information available to the public. Their store page on Walmart indicates the seller offers many types of products, from clothing to home goods and more.  

 This seems like a good bargain as a gift for someone who is always losing their keys or wallet or wants to make sure their bicycle is secure when they lock it up somewhere. But purchasing these types of “smart” devices with so much uncertainty poses a few issues. 

If you do experience some sort of security failure or issue, there is no easy way to contact any of these vendors through the traditional means that the average user would go searching for. These vendors have no clear history of responsibly disclosing vulnerabilities, releasing security updates, or testing their products’ security before release. 

When these types of gifts are dealing with such high-profile information like your personal information, health data, or physical location, users should be confident that their information is being stored correctly and securely, or at least there’s a way to contact the vendor should they have any questions. 

When searching for holiday gifts online, make sure you’re buying from a trusted vendor, or if you haven’t heard of the vendor before, take a few extra minutes just to look them up, read their app’s privacy policy, or even read the reviews to make sure there’s no clear sign of bot activity like repetitive words or phrases or using the same photo for multiple reviews.  

**The one big thing **

The 2023 Cisco Talos Year in Review is now available to download. Once again, the Talos team has meticulously combed through a massive amount of data to analyze the major trends that have shaped the threat landscape in 2023. Global conflict influenced a lot of these trends, altering the tactics and approaches of many threat actors. In operations ranging from espionage to cybercrime, we’ve seen geopolitical events have a significant impact on the way these are carried out. 

**Why do I care? **

The Year in Review report includes new data and telemetry from Talos about attacker trends, popular malware seen in the wild, and much more. Despite the accelerated pace of many threat actor campaigns and the geopolitical events that shaped them, our report shows that the defensive community’s diligence, inventiveness and collaborative efforts are helping to push adversaries back.   

**So now what? **

Download our full report here, bookmark the Year in Review landing page for future content we have planned around the report, and listen to the Beers with Talos episode that covers the details of the report. 

**Top security headlines of the week **

**More than six million people are reportedly victims of a large data breach at DNA and genealogy testing firm 23andMe.** The breach is larger than initially expected, with more than 5.5 million users who opted into the company’s “DNA Relatives” feature, which allows customers to automatically share some of their data with other users. Another 1 million-plus users had their family tree information accessed. The attackers accessed the accounts because of password reuse from users, likely who used easy-to-guess login information or passwords they used across multiple other accounts. 23andMe was not the target of the initial breach, nor was a company account the source of the compromised credentials. Security experts are urging users to move away from traditional username-and-password login methods as these types of attacks happen more often, instead moving toward multi-factor authentication or passwordless logins. (TechCrunch, Wall Street Journal) 

**Apple released emergency fixes for two zero-day vulnerabilities in its WebKit browser engine that have already been exploited in the wild.** The company reported that the flaws are being exploited on devices running on iOS versions before iOS 16.7.1 (released on Oct. 10, 2023). There are new patches available, which users should install immediately, in iOS, iPadOS, macOS Sonoma and the Safari web browser. The two vulnerabilities tracked as CVE-2023-42916 and CVE-2023-42917, leave affected devices vulnerable to adversaries accessing sensitive information on targeted devices. CVE-2023-42917 could also allow an attacker to execute arbitrary code on the targeted machine. (SC Magazine, Decipher) 

**Security researchers say a new threat actor known as “AeroBlade” compromised a U.S. aerospace company for more than a year.** The actor reportedly started testing their malware and infection chain on the targeted network in September 2022 and executed malware on the network in July 2023. The activity sat undetected for months due to anti-analysis techniques. It is currently unknown what actions, if any, the actor carried out during that time or if they compromised any user or customer data. The initial infection began with a Microsoft Word lure document with the title, “"SOMETHING WENT WRONG Enable Content to load the document." The ensuing malicious Microsoft Word template (DOTM) file then loaded a DLL that served as a reverse shell. Researchers say the attacker’s intent was likely to steal data from the target to sell it, potentially supply it to international competitors, or use it to extort the target into paying a ransom. (Dark Reading, Bleeping Computer)  

**Can’t get enough Talos? **

Security journalists from Decipher bring you the headlines, including new U.S. government sanctions on threat actor groups in our latest Threat Spotlight video.

Then, Hazel chats to Talos security researcher Joe Marshall to discuss the Talos 2023 Year in Review, and Project PowerUp, the story of how Cisco Talos worked with a multi-national, multi-company coalition of volunteers and experts to help “keep the lights on” in Ukraine, by injecting a measure of stability in Ukraine’s power transmission grid.

Cybersecurity considerations to have when shopping for holiday gifts

Android phones are vulnerable to attacks that allow a remote execution of malicious code and it requires no user interaction.

Android phones are vulnerable to attacks that could allow someone to takeover a device remotely without the device owner needing to do anything.

Updates for these vulnerabilities and more are included in Google’s Android security bulletin for December. In total, there are patches for 94 vulnerabilities, including five rated as “Critical.”

The most severe of these flaws is a vulnerability in the System component that could lead to remote code execution (RCE) without any additional execution privileges required. User interaction is not needed for exploitation.

This vulnerability, referenced as CVE-2023-40088, affects a function that is used for Bluetooth communication, so the “remote” part is limited to “close range” since the average Bluetooth range is about 30 feet (10 meters). Successful manipulation with a specially crafted input leads to a use after free vulnerability. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code.

Another critical vulnerability (CVE-2023-40077) that looks problematic is an Elevation of Privilege (EoP) vulnerability in the Android Framework. Successful exploitation could lead to a race condition. A race condition, or race hazard, is the behavior of a system where the output depends on the sequence or timing of other uncontrollable events. It becomes a bug when events do not happen in the order the programmer intended. In this case it could provide a successful attacker with permissions to perform actions they shouldn’t be able to.

Security patch levels of 2023-12-05 or later address all of these issues. To learn how to check a device’s security patch level, see how to check and update your Android version. The updates have been made available for Android 11, 12, 12L, 13, and 14. Android partners are notified of all issues at least a month before publication, however, this doesn’t always mean that the patches are available for devices from all vendors. Android vendors such as Samsung and OnePlus have pledged to release security updates once a month. Google usually ships out security updates to Pixel phones within two weeks or sooner.

**We don’t just report on vulnerabilities—we identify them, and prioritize action.**

Cybersecurity risks should never spread beyond a headline. Keep vulnerabilities in tow by using ThreatDown Vulnerability and Patch Management.

In parse_gap_data of utils.cc, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with User execution privileges needed. User interaction is not needed for exploitation.

_Published December 4, 2023_

The Android Security Bulletin contains details of security vulnerabilities affecting Android devices. Security patch levels of 2023-12-05 or later address all of these issues. To learn how to check a device's security patch level, see Check and update your Android version.

Android partners are notified of all issues at least a month before publication. Source code patches for these issues will be released to the Android Open Source Project (AOSP) repository in the next 48 hours. We will revise this bulletin with the AOSP links when they are available.

The most severe of these issues is a critical security vulnerability in the System component that could lead to remote (proximal/adjacent) code execution with no additional execution privileges needed. User interaction is not needed for exploitation. The severity assessment is based on the effect that exploiting the vulnerability would possibly have on an affected device, assuming the platform and service mitigations are turned off for development purposes or if successfully bypassed.

Refer to the Android and Google Play Protect mitigations section for details on the Android security platform protections and Google Play Protect, which improve the security of the Android platform.

**Android and Google service mitigations**

This is a summary of the mitigations provided by the Android security platform and service protections such as Google Play Protect. These capabilities reduce the likelihood that security vulnerabilities could be successfully exploited on Android.

*   Exploitation for many issues on Android is made more difficult by enhancements in newer versions of the Android platform. We encourage all users to update to the latest version of Android where possible.
*   The Android security team actively monitors for abuse through Google Play Protect and warns users about Potentially Harmful Applications. Google Play Protect is enabled by default on devices with Google Mobile Services, and is especially important for users who install apps from outside of Google Play.

CVE-2023-45781: Android Security Bulletin—December 2023

Hundreds of consumer and enterprise-grade x86 and ARM models from various vendors, including Intel, Acer, and Lenovo, are potentially vulnerable to bootkits and takeover.

Source: Tetra Images via Alamy Stock Photo

Researchers have uncovered "LogoFAIL," a set of critical vulnerabilities present in the Unified Extensible Firmware Interface (UEFI) ecosystem for PCs.

Exploitation of the vulnerabilities nullify essential endpoint security measures and provide attackers with deep control over affected systems.

The flaws originate in image-parsing libraries within the boot process, impacting all major device manufacturers on both x86 and ARM-based devices, according to a Binarly Research report that will be officially released at Black Hat Europe in London next week.

The severity of LogoFAIL is exacerbated by its widespread reach, researchers warn, noting that it affects the entire ecosystem, not just individual vendors here and there. The findings were reported via the CERT/CC VINCE system, with anticipated vendor patches scheduled for December 6, in tandem with the Black Hat talk, which is entitled, "LogoFAIL: Security Implications of Image Parsing During System."

**Hijacking the Boot Process With LogoFAIL**

Binarly researchers found that by embedding compromised images in the EFI System Partition (ESP) or unsigned firmware update sections, threat actors can execute malicious code during boot-up, enabling them to hijack the boot process.

This exploitation bypasses crucial security measures like Secure Boot and Intel Boot Guard, facilitating the insertion of a persistent firmware bootkit operating beneath the OS level.

"Because the attacker is getting the privileged code execution into the firmware, it's bypassing the security boundaries by design, like a Secure Boot," explains Alex Matrosov, CEO and founder of Binarly. "The Intel Boot Guard and other trusted boot technologies are not extended in runtime, and after the firmware is verified, it just boots further in the system boot flow."

He says the Binarly Research team originally was experimenting with logo modification on one of the Lenovo devices they have in the lab.

"One day, it suddenly started to reboot after showing the boot logo," he says. "We realized that the root cause of the issue was the change of the original logo, which led to a deeper investigation."

He adds, "In this case, we are dealing with continued exploitation with a modified boot logo image, triggering the payload delivery in runtime, where all the integrity and security measurements happen before the firmware components are loaded.”

This is not the first Secure Boot bypass ever discovered; in November 2022, a firmware flaw was found in five Acer laptop models that could be used to disable Secure Boot and allow malicious actors to load malware; and the BlackLotus or BootHole threats have opened the door to boot process hijacking before. However, Matrosov says that LogoFAIL differs from prior threats because it doesn't break runtime integrity by modifying the bootloader or firmware component.

In fact, he says LogoFAIL is a data-only attack, occurring when malicious input comes from the firmware image or the logo is read from the ESP partition during the system boot process — and thus, it's hard to detect.

"Such an approach with the ESP attack vector leaves zero evidence of the firmware attack inside the firmware itself, since the logo comes from an outside source," he explains.

**Majority of the PC Ecosystem Is Vulnerable**

Devices equipped with firmware from the three major independent BIOS vendors (IBVs), Insyde, AMI, and Phoenix, are susceptible, indicating a potential impact across diverse hardware types and architectures. Between them, the three cover 95% of the BIOS ecosystem, Matrosov says.

In fact, Matrosov says LogoFAIL affects "most devices worldwide," including consumer and enterprise-grade PCs from various vendors —Acer, Gigabyte, HP, Intel, Lenovo, MSI, Samsung, Supermicro, Fujitsu, and "many others."

"The exact list of affected devices is still being determined, but it's crucial to note that all three major IBVs — AMI, Insyde, and Phoenix — are impacted due to multiple security issues related to image parsers they are shipping as a part of their firmware," the Binarly report warned. "We estimate LogoFAIL impacts almost any device powered by these vendors in one way or another."

For its part, Phoenix Technologies published an early security notification this week (now taken down but available as a cache until it goes back up Dec. 6) detailing that the bug (CVE-2023-5058) is present in all versions lower than 1.0.5 of its Phoenix SecureCore Technology 4, which is a BIOS firmware that provides advanced security features for various devices.

"The flaw exists in the processing of user-supplied splash screen during system boot, which can be exploited by an attacker who has physical access to the device," according to the notification, which noted that an updated version is available. "By supplying a malicious splash screen, the attacker can cause a denial-of-service attack or execute arbitrary code in the UEFI DXE phase, bypassing the Secure Boot mechanism and compromising the system integrity."

LogoFAIL is also tracked by Insyde as CVE-2023-40238, and by AMI as CVE-2023-39539 and CVE-2023-39538.

Matrosov says the company is actively collaborating with multiple device vendors to coordinate disclosure and mitigation efforts across the spectrum.

**Firmware Updates Key to Minimizing Risk**

To minimize firmware risk in general, users should stay updated with manufacturer advisories and promptly apply firmware updates, as they often address critical security flaws.

Also, vetting suppliers is a must. "Be picky about the device vendors you rely on daily as personal device or devices across your enterprise infrastructure," Matrosov adds. "Don't blindly trust the vendors, but rather validate the vendor's security promises and identify the gaps across your device inventory and beyond."

Critical 'LogoFAIL' Bugs Offer Secure Boot Bypass for Millions of PCs

Fake Facebook ads seem to be the flavor of the month for scammers.

Thursday, November 30, 2023 14:00

I know I’m a little late to the party to hit the prime SEO for Black Friday, Cyber Monday and holiday shopping. But if I know the readers of this newsletter, everyone is far from done with their holiday shopping already after a few days. 

I also know I’m far from the only person to warn consumers about scams during this season, so I’m trying to split the difference and highlight a few specific scams and spam campaigns that are already circulating in the wild, some of which popped up right on Black Friday, so you don’t get caught in the remaining days leading up to the winter holidays. 

Fake Facebook ads seem to be the flavor of the month for scammers. This is completely anecdotal, but my mom almost got “got” with a fake Facebook post in a group she belongs to claiming to have some great deals on Nintendo Switch games on Amazon that were not actually real (thankfully she hadn’t clicked the link before she asked me if “Mario Odyssey” was a good deal at $15).  

Still, several other reports have shown that scammers are using Facebook ads to advertise a deal for a $19 Stanley cup — these are the water bottles all the influencers are using nowadays and, even when they are on sale, don’t go for any less than about $35. In this case, it looks like the actors are just looking to take your money or credit card information with a fake ordering process and no plans to send you anything. 

Adversaries have also set up fake Facebook pages and web pages disguising themselves as the retailer Big Lots. These fake ads and posts offer vague deals and sales on various products but instead point to typo-squatted Big Lots websites (or URLs that vaguely seem like they could be connected to Big Lots).  

Scammers are also sending mass emails to subscribers of various streaming services like Amazon Prime, Paramount+ and Peacock claiming that their subscription has lapsed, but they can resubscribe for a deeply discounted price, or even free, as part of a Black Friday special.  

Amazon also issued a warning recently that attackers have been sending emails with malicious attachments asking for users' personal information in exchange for having their “accounts” unlocked. 

This is just a sampling of the likely hundreds of different scams and spam campaigns attackers are deploying right now, so in general, when shopping online, here are a few tips: 

*   Only download apps from trusted and official app stores like the Google Play store and iOS App Store. 
*   Look out for apps that ask for suspicious permissions, such as access to your text messages, contacts, stored passwords and administrative features. 
*   Some malicious apps will try to masquerade as a legitimate version of the one you could be searching for. Signs of these apps include poor spelling and grammar in app descriptions and interfaces, lack of high-quality performance and a developer contact that uses a free email service (such as @gmail.com). 
*   Avoid clicking on unsolicited emails. Make sure you purposefully subscribed to any marketing emails you receive from retailers before opening it. 
*   Use an ad blocker locally on your browser. These will often block any malvertising campaigns that aim to capitalize on shoppers looking for deals. 
*   Try to use payment services such as Google Pay, Samsung Pay and Apple Pay. These services use tokenization instead of the “Primary Account Number” (your credit card number), making your transaction more secure. 
*   Use unique, complex passwords, per site. Attackers commonly reuse passwords to compromise multiple accounts with the same username. Use a password locker if you have a hard time creating and remembering secure passwords. 
*   Manually type in URLs to sites you want to visit rather than clicking on links. 
*   Use multi-factor authentication, such as Cisco Duo, to log into your email account to avoid unauthorized access. 

Next week, Talos will have a holiday special of our own! On Dec. 5, we’ll be launching our second-ever Year in Review report, complete with all new data and insights about the attacks and malware we’ve seen in 2023. Stay tuned to our social media channels or blog for that release.  

**The one big thing **

Cisco Talos recently discovered a malicious campaign that likely started as early as August 2023, delivering a new remote access trojan (RAT) we dubbed “SugarGh0st.” We assess with high confidence that the SugarGh0st RAT is a new customized variant of Gh0st RAT, an infamous trojan that’s been active for more than a decade, with customized commands to facilitate the remote administration tasks as directed by the C2 and modified communication protocol based on the similarity of the command structure and the strings used in the code. 

**Why do I care? **

If infected, SugarGh0st serves as a fully functional backdoor for the adversary that can execute most remote-control functionalities. It can launch the reverse shell and run the arbitrary commands sent from C2 as strings using the command shell. SugarGh0st can collect the victim’s machine hostname, filesystem, logical drive, and operating system information. It can access the running process information of the victim’s machine and control the environment by accessing the process information and terminating the process as directed by the C2 server. It can also manage the machine’s service manager by accessing the configuration files of the running services and can start, terminate or delete the services. 

**So now what? **

Since this seems to be an offshoot of GhostRAT, we certainly can’t rule out any other variants that may be floating out there. Talos also has new ClamAV signatures, Snort rules and other Cisco Secure protection to specifically detect and stop SugarGh0st.  

**Top security headlines of the week **

**Cisco Talos and other teams across Cisco recently worked with multiple government partners to help protect the Ukrainian power grid and ensure it runs appropriately.** The effort, spearheaded by Talos’ Joe Marshall, involved creating bespoke hardware for Ukraine’s energy supplier, Ukrenergo, to operate in place of traditional GPS devices that the Ukrainian power grid relies on to keep running on time. GPS satellites and Ukrainian substations have constantly been the target of kinetic and cyber threats during Russia’s invasion of Ukraine. Officials from multiple U.S. government agencies assisted in the project.  The Pentagon set up flights to physically deliver the manipulated switches, the Department of Energy helped coordinate the equipment’s delivery, and, as Ukrenergo told CNN, the Department of Commerce was a part of critical meetings that first outlined this project. Taras Vasyliv, who oversees power dispatching for Ukrenergo, told CNN that the custom-built switches were the equivalent of a “flashlight” for a surgeon who is trying to operate in the dark. (CNN, Business Insider) 

**Leaked government documents show that some local, federal and state law enforcement officers have been able to view the phone records of millions of Americans,** even those who have not been accused or suspected of a crime. The little-known Pentagon program was partially uncovered because of a letter sent from U.S. Sen. Ron Wyden of Oregon to U.S. Attorney General Merrick Garland, in Wyden’s office requested more information on the project and encouraged the federal government to publicly disclose this knowledge. The letter states the White House pays wireless company AT&T to give all federal, state, local, and Tribal law enforcement agencies “the ability to request often-warrantless searches.” Known as the “Hemisphere Project,” this program has apparently been around since 2007 and reported on by the New York Times in 2013 but has largely gone unnoticed since. Wyden is attempting to challenge the legality of the Hemisphere Project. (Wired) 

**Security researchers have found a way to bypass the Microsoft Hello login authentication system** used in many fingerprint readers and face ID scanners on devices from Dell, Lenovo and Microsoft. Researchers hired by Microsoft to test the security of the readers have since informed the company of these vulnerabilities. The attack the researchers outlined could provide access to a stolen laptop or carry out what's called an “evil maid” attack on an unattended device. Microsoft introduced Hello with its Windows 10 operating system, and since then has included fingerprint scanners on all its devices (though in some cases, Microsoft’s own hardware like the Surface tablet did not use Hello). Though the manufacturers are now aware of these vulnerabilities, the variety of attacks means it can be difficult to patch for these issues. However, all the attacks ultimately required physical access to a device. (Ars Technica, The Verge)

Plus: Major security patches from Microsoft, Mozilla, Atlassian, Cisco, and more.

The holiday season is here, but software firms are still busy issuing fixes for major security flaws. Microsoft, Google, and enterprise software firm Atlassian have released patches for vulnerabilities already being used in attacks. Cisco also patched a bug deemed so serious, it was given a near-maximum CVSS score of 9.9.

Here’s everything you need to know about the patches released in November.

Google Chrome

Google ended November with a bang after issuing seven security fixes for Chrome, including an emergency patch for an issue already being used in real-life attacks. Tracked as CVE-2023-6345, the already exploited flaw is an integer overflow issue in Skia, an open source 2D graphics library. “Google is aware that an exploit for CVE-2023-6345 exists in the wild,” the browser maker said in an advisory.

Little is known about the fix at the time of writing; however, it was reported by Benoît Sevens and Clément Lecigne of Google's Threat Analysis Group, indicating the exploit could be spyware-related.

The six other flaws fixed by Google and rated as having a high impact include CVE-2023-6348, a type-confusion bug in Spellcheck, and CVE-2023-6351, a use-after-free issue in libavif.

Earlier in the month, Google released fixes for 15 security issues in its widely used browser. Among the bugs fixed by the software giant are three rated as having a high severity. Tracked as CVE-2023-5480, the first is an inappropriate implementation issue in Payments, while the second, CVE-2023-5482, is an insufficient data validation flaw in USB with a CVSS score of 8.8. The third high-severity bug, CVE-2023-5849, is an integer overflow issue in USB.

Mozilla Firefox

Chrome competitor Firefox has fixed 10 vulnerabilities in the browser, six of which are rated as having a high impact. CVE-2023-6204 is an out-of-bound memory access flaw in WebGL2 blitFramebuffer, while CVE-2023-6205 is a use-after-free issue in MessagePort.

Meanwhile, CVE-2023-6206 could allow clickjacking permission prompts using the full-screen transition. “The black fade animation when exiting full screen is roughly the length of the anti-clickjacking delay on permission prompts,” Firefox owner Mozilla said. “It was possible to use this fact to surprise users by luring them to click where the permission grant button would be about to appear.”

CVE-2023-6212 and CVE-2023-6212 are Memory safety bugs, both with a CVSS score of 8.8, in Firefox 120, Firefox ESR 115.5, and Thunderbird 115.5.

Google Android

Google's November Android Security Bulletin details fixes patched in this month, including eight in the Framework, six of which are elevation of privilege bugs. The worst flaw could lead to local escalation of privilege with no additional execution privileges needed, Google said in an advisory.

Google also fixed seven issues in the System, six of which are rated as having a high severity and one marked as critical. Tracked as CVE-2023-40113, the critical bug could lead to local information disclosure with no additional execution privileges needed.

Google's Pixel devices have already received the November update, along with some additional fixes. The November Android Security Bulletin has also started to roll out to some of Samsung’s Galaxy line.

Microsoft

Microsoft has a Patch Tuesday every month, but November's is worth notice. The update fixes 59 vulnerabilities, two of which are already being exploited in real-life attacks. Tracked as CVE-2023-36033, the first is an elevation of privilege vulnerability in Windows DWM Core Library marked as important, with a CVSS score of 7.8. “An attacker who successfully exploited this vulnerability could gain SYSTEM privileges,” Microsoft said.

Meanwhile, CVE-2023-36036 is an elevation of privilege vulnerability in Windows Cloud Files Mini Filter Driver with a CVSS score of 7.8. Also fixed in November’s update cycle is the already exploited libWep flaw previously fixed in Chrome and other browsers, which also impacts Microsoft’s Edge, tracked as CVE-2023-4863.

Another notable flaw is CVE-2023-36397, a remote code execution vulnerability in Windows Pragmatic General Multicast marked as critical with a CVSS score of 9.8. “When Windows message queuing service is running in a PGM Server environment, an attacker could send a specially crafted file over the network to achieve remote code execution and attempt to trigger malicious code,” Microsoft said.

Cisco

Enterprise software firm Cisco has issued fixes for 27 security flaws, including one rated as critical with a near maximum CVSS score of 9.9. Tracked as CVE-2023-20048, the vulnerability in the web services interface of Cisco Firepower Management Center Software could allow an authenticated, remote attacker to execute unauthorized configuration commands on a Firepower Threat Defense device managed by the FMC Software.

However, to successfully exploit the vulnerability, an attacker would need valid credentials on the FMC Software, Cisco said.

A further seven of the flaws fixed by Cisco are rated as having a high impact, including CVE-2023-20086—a denial-of-service flaw with a CVSS score of 8.6—and CVE-2023-20063, a code-injection vulnerability with a CVSS score of 8.2.

Atlassian

Atlassian has released a patch to fix a serious flaw already being used in real-life attacks. Tracked as CVE-2023-22518, the improper-authorization vulnerability issue in Confluence Data Center and Server is being used in ransomware attacks. “As part of Atlassian's ongoing monitoring and investigation of this CVE, we observed several active exploits and reports of threat actors using ransomware,” it said.

Security outfit Trend Micro reported the Cerber ransomware group is using the flaw in attacks. “This is not the first time that Cerber has targeted Atlassian—in 2021, the malware re-emerged after a period of inactivity and focused on exploiting remote code execution vulnerabilities in Atlassian's GitLab servers,” Trend Micro said.

All versions of Confluence Data Center and Server are affected by the flaw, which allows an unauthenticated attacker to reset Confluence and create an administrator account. “Using this account, an attacker can perform all administrative actions available to a Confluence instance administrator, leading to a full loss of confidentiality, integrity and availability,” Atlassian said.

SAP

Enterprise software giant SAP has released its November Security Patch Day, fixing three new flaws. Tracked as CVE-2023-31403 and with a CVSS score of 9.6, the most serious issue is an improper access control vulnerability flaw in SAP Business One. As a result of exploiting the issue, a malicious user could read and write to the SMB shared folder, the software giant said.
