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.

A new study that looked at the password requirements of the most popular websites came to a disappointing but not surprising conclusion.

A new study that examines the current state of password policies across the internet shows that many of the most popular websites allow users to create weak passwords.

For the Georgia Tech study, the researchers designed an algorithm that automatically determined a website’s password policy. With the help of machine learning, they could see the consistency of length requirements and restrictions for numbers, upper- and lower-case letters, special symbols, combinations, and starting letters. They could also see if sites permitted dictionary words or known breached passwords.

Using this tool they found:

*   12% of the websites they looked at completely lack password length requirements
*   3 out of 4 fail to meet minimum requirement standards which means they:
    
    *   Allow very short passwords
    
    *   Do not block common passwords
    
    *   Use outdated requirements like complex characters

More than half of the websites in the study accepted passwords with six characters or less, with 75% failing to require the recommended eight-character minimum. Around 12% of the websites had no length requirements, and 30% did not support spaces or special characters.

Giving users that kind of freedom is asking for them to be duped. As we pointed out a while back, even tech-savvy users like IT administrators resort to awful passwords when given the chance.

The reasons for not enforcing standards are obvious. Most websites care more about customer satisfaction than security, and you can guess which one is better for business.

Users don’t like passwords, especially since the password situation has been made worse by ridiculous and unnecessary rules, such as asking users to pick passwords that follow formulas, or forcing users to change their password every few months. Both rules have been discredited but continue to haunt us. Formulas reduce the number of possible passwords a user can pick from, and regular password resets encourage users to pick passwords that conform to a predictable pattern, both of which can make guessing passwords easier, which is the opposite of what we want.

If you’d like to read more about this, read “Why (almost) everything we told you about passwords was wrong.” The article summarizes how a lot of what you’ve been told about passwords over the years was either wrong (change your passwords as often as your underwear), misguided (choose long, complicated passwords), or counterproductive (don’t reuse passwords).

We feel that we should entirely move away from the model that requires users to create and remember passwords. It is time for something more secure AND user-friendly. And it’s not like these systems don’t exist (hello Passkeys), we just need to embrace them more widely.

Let’s enable muti-factor authentication (MFA) where we can, even if we feel that using a password as the first factor doesn’t add a lot of extra security to the login procedure. And if we need to rely on passwords alone, try using a password manager. They help you create complex passwords and remember them for you.

The full report of the researchers will be presented at the ACM Conference on Computer and Communications Security (CCS) in Copenhagen, Denmark, later this month.
