New web targets for the discerning hacker

New web targets for the discerning hacker

The US Department of Justice (DoJ) has said it won’t prosecute security researchers acting “in good faith”, as part of changes to the Computer Fraud and Abuse Act (CFAA). While the DoJ says this was always the case in practice, the changes provide more certainty for researchers, pen testers, and bug bounty hunters.

Meanwhile, the UK government remains half-hearted about bug bounty programs, with Dr Ian Levy, technical director of the UK’s National Cyber Security Centre (NCSC), saying there are no plans for a broad rollout any time soon. Speaking at the CyberUK conference, he commented: “The reason for that is that we just don’t seem to need to – people are more than happy to come and tell government we’ve screwed up.”

LinkedIn, meanwhile, has launched a public bug bounty program with rewards of up to $18,000 that replaces its invite-only program. Hosted by HackerOne, LinkedIn invites hackers to probe its main web domain, LinkedIn.com, for security flaws, as well as the LinkedIn API and Android and iOS mobile apps.

Blockchain bridge Wormhole has handed over a record $10 million reward to a bug hunter with the online pseudonym ‘satya0x’. Had it been exploited successfully, the critical vulnerability that attracted the reward could have seen all the funds residing in in the Wormhole core bridge contract on Ethereum lost forever.

In other payout news, Youssef Sammouda netted $44,625 for discovering a series of bugs that could have allowed a malicious actor to take over Facebook accounts. They included a cross-site request forgery (CSRF) bug allowing an attacker to force a victim to log out from their Facebook account in their browser, and a flaw forcing a login to the attacker’s Facebook account inside the victim’s browser.

Pwn2Own Vancouver, the flagship hacking contest, took place last month, handing out more than $1 million for bugs in products from Microsoft, Mozilla, Apple, and others. Participants unearthed 27 qualifying vulnerabilities in total, with a team from Star Labs in Singapore being crowned this year’s Masters of Pwn.

And finally, Vidoc Security Lab has published a security advisory warning of more than 60 instances of a web security flaw in the Swagger-UI library, potentially leading to account takeover. Bug bounty programs operated by PayPal, Shopify, Atlassian, Microsoft, GitLab, and Yahoo were alerted, among others.

Plus: Google patches 36 Android vulnerabilities, Cisco fixes three high-severity issues, and VMWare closes two “serious” flaws.

May has been another busy month of security updates, with Google’s Chrome browser and Android operating system, Zoom, and Apple’s iOS releasing patches to fix serious vulnerabilities.

Meanwhile, things have not run smoothly for Microsoft, which was forced to issue an out-of-band update after a disastrous Patch Tuesday during the month. And Cisco, Nvidia, Zoom, and VMWare all issued patches for pressing flaws.

Here’s what you need to know.

Apple iOS and iPadOS 15.5, macOS Big Sur 11.6.6, tvOS 15.5, watchOS 8.6

With Apple due to announce iOS 16 at its Worldwide Developers Conference in June, the iPhone maker released probably its last major iOS 15-point update in May. It came with new features, but iOS and iPadOS 15.5 also fixed 34 security vulnerabilities, some of which are serious.

Security issues fixed in iOS 15.5 include flaws in the Kernel, as well as in the WebKit browser engine, according to Apple’s support page. Thankfully, none of the issued patches in iOS and iPad 15.5 are being used in attacks, according to the company, but that doesn’t mean they won’t be if you don’t update now.

Meanwhile, users of macOS, tvOS, and the Apple Watch should update their devices ASAP, as Apple also issued an emergency update to patch an issue it believes is already being used in attacks. The flaw in Apple AVD, labeled CVE-2022-22675, could allow an app to execute code with Kernel privileges. Issues in the Kernel are as bad as it gets, so it’s worth checking and updating your devices right away.

Microsoft’s Flubbed May Patch Tuesday

Microsoft’s May Patch Tuesday was something of a disaster for the diligent businesses that installed it straight away.

On May 10, the firm issued security updates to fix 75 vulnerabilities, eight labeled as serious and three that were being exploited by attackers. The issues fixed in May’s Patch Tuesday were important, but there were soon problems for some Microsoft users, who reported authentication failures after installing the latest updates. It impacted people using the client and server Windows platforms and systems running all Windows versions, including Windows 11 and Windows Server 2022.

In a bid to fix the problem, the firm was forced to issue an out-of-band update for Windows 10, Windows 11, and Windows Server 2008, 2012, 2016, 2019, and 2022 on May 20. The update won’t install automatically—you need to download it from Microsoft’s update catalog.

Firefox 100.0.2

In early May, Mozilla released Firefox 100, including nine security fixes for its Firefox browser, of which seven were rated as high severity. But later in May, ethical hackers at the Pwn20wn competition in Vancouver were able to demonstrate how attackers could execute JavaScript code on devices running the latest Mozilla software. Mozilla fixed the issues in another updateFirefox 100.0.2, Firefox ESR 91.9.1, Firefox for Android 100.3, and Thunderbird 91.9.1. Click those update buttons.

Android

May’s Android security update is a big one, patching 36 vulnerabilities, including an issue already being exploited by attackers. This exploited flaw is a privilege escalation bug in the Linux Kernel known as “The Dirty Pipe.”

The flaw, which impacts newer Android devices running Android 12 and later, was disclosed by Google in February, but it has taken a while to reach devices.

Validation check loopholes exposed

Malicious actors can take unauthorized ownership of online accounts even before their victims sign up for services, according to new research backed by the Microsoft Security Response Center (MSRC).

Dubbed ‘account pre-hijacking’, the class of attack involves an attacker setting an account takeover exploit in motion before the victim has even registered with an online service. After the victim signs up, the attacker takes advantage of security holes in the service’s authentication mechanisms to access or take ownership of the newly-created account.

The study (PDF) found dozens of high-traffic services to be vulnerable to at least one type of pre-hijacking attack. The research sheds light on the security issues surrounding account creation, a seldom scrutinised issue.

**More than one way to pre-hijack an account**

The research was supported by one of the Identity Project Research Grants awarded by the MSRC in early 2020.

“In this project, we explored several topics, but soon noticed a pattern emerging around the ‘pre-hijacking’ threat model,” Andrew Paverd, a senior researcher at MSRC, and independent researcher Avinash Sudhodanan told The Daily Swig.

Account pre-hijacking assumes that the victim doesn’t yet have an account on the target service and the attacker knows the email and other basic details of the victim. The researchers discovered five types of pre-hijacking attack scenarios.

Some take advantage of multiple account creation modes supported by many online services. On many websites, users can directly provide an email address and password to create their account or use federated authentication by using a consumer-focused single sign-on (SSO) service, as provided by the likes of Facebook, Google, and Microsoft.

DON’T FORGET TO READ Security ‘researcher’ hits back against claims of malicious CTX file uploads

For example, in one type of attack, the attacker creates an account with the victim’s email address. The victim then creates an account using the federated approach. In some services, this merges the attacker’s and victim’s accounts, giving them both simultaneous access to the same account.

In another type of attack, the attacker creates an account with the victim’s email and associates their own federated identity to the same account. When the victim tries to create their account, they will be prompted to reset their password. The victim will obtain access to the account, but the attacker will also be able to access the account through the SSO identity.

The researchers said: “It’s very positive to see how many online services are moving towards single sign-on \[but\] this means that they might have to support multiple login mechanisms. This in itself is not necessarily an issue, and many services do this securely.

“Our research simply points out some subtle pitfalls to be aware of when supporting multiple login mechanisms,” the researchers added.

**Switch hitter**

Paverd and Sudhodanan pointed out that three of the attacks they found do not require the service to support multiple login mechanisms.

For example, in one scheme, the attacker’s session might remain active even after the victim recovers their account and resets the password.

Catch up on the latest authentication news and analysis

In yet another scenario, the attacker creates an account with the victim’s email and initiates an email change request to the attacker’s own email address. The attacker then waits for the victim to claim the account before completing the email change request and taking ownership of the account.

**Top services affected**

In their study, the researchers examined 75 services that ranked among Alexa’s list of top-150 high-traffic domains. At least 35 were affected by one or more account pre-hijacking attacks, including Dropbox, Instagram, LinkedIn, WordPress.com, and Zoom. Fortunately, all the affected services were notified of the vulnerabilities and have implemented the necessary fixes.

“We think that a lack of awareness may have been the main cause of these potential vulnerabilities. We are therefore publishing this research to raise awareness and help organizations mitigate these vulnerabilities,” Paverd and Sudhodanan said.

The most important takeaway, the researchers concluded, is “to verify that the user actually owns any user-supplied identifiers (e.g., email address or phone number) before using them to create a new account or adding them to an existing account”. This would mitigate all types of pre-hijacking attacks identified to date.

The researchers’ paper also describes several other possible defense-in-depth strategies.

They recommended that users enable multi-factor authentication (MFA) whenever possible because it stops most pre-hijacking attacks they uncovered.

Another sign of account pre-hijacking is receiving an email about an account that you did not create, which users usually ignore. “Report this to the relevant website,” the researchers said.

On Monday May 30, 2022, Microsoft issued CVE-2022-30190 regarding the Microsoft Support Diagnostic Tool (MSDT) in Windows vulnerability. On Tuesday June 14, 2022, Microsoft issued Windows updates to address this vulnerability. Microsoft recommends installing the following KB5015805 for Windows 8.1 and below according to the following table. The defense in depth fix is incorporated into the cumulative updates for Windows 10 and newer.

A remote code execution vulnerability exists when MSDT is called using the URL protocol from a calling application such as Word. An attacker who successfully exploits this vulnerability can run arbitrary code with the privileges of the calling application. The attacker can then install programs, view, change, or delete data, or create new accounts in the context allowed by the user’s rights.

**Workarounds Workarounds**

**To disable the MSDT URL Protocol**

Disabling MSDT URL protocol prevents troubleshooters being launched as links including links throughout the operating system. Troubleshooters can still be accessed using the Get Help application and in system settings as other or additional troubleshooters. Follow these steps to disable:

1.  Run **Command Prompt** as **Administrator**.
2.  To back up the registry key, execute the command “reg export HKEY_CLASSES\_ROOT\\ms-msdt \_filename_”
3.  Execute the command “reg delete HKEY\_CLASSES\_ROOT\\ms-msdt /f”.

**How to undo the workaround**

1.  Run **Command Prompt** as **Administrator**.
2.  To restore the registry key, execute the command “reg import _filename”_

**Microsoft Defender Detections & Protections Microsoft Defender Detections & Protections****Microsoft Defender Antivirus (MDAV) Microsoft Defender Antivirus (MDAV)**

**FAQ FAQ**

**Q:** Does Protected View and Application Guard for Office provide protection from this vulnerability?

**A:** If the calling application is a Microsoft Office application, by default, Microsoft Office opens documents from the internet in Protected View or Application Guard for Office, both of which prevent the current attack.

*   For information about Protected View, see What is Protected View?
*   For information about Application Guard for Office, see Application Guard for Office.

**Q:** Is configuring the GPO setting **Computer Configuration\\Administrative Templates\\System\\Troubleshooting and Diagnostics\\Microsoft Support Diagnostic Tool\\“Microsoft Support Diagnostic Tool: Turn on MSDT interactive communication with support provider”** to **“Disabled”** another workaround?

Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \Software\Policies\Microsoft\Windows\ScriptedDiagnosticsProvider\Policy\ Value Name: DisableQueryRemoteServer Type: REG_DWORD Value: 0

**A:** No, this GPO does not provide protection against this vulnerability. “Interactive communication with support provider” is a special mode MSDT runs in when launched with no parameters which has no impact on MSDT support for URL protocol.

**Q:** Is configuring the GPO setting **Computer Configuration - Administrative Templates - System - Troubleshooting and Diagnostics - Microsoft Support Diagnostic Tool\\“Troubleshooting: Allow users to access recommended troubleshooting for known problems”** to " **Disabled**" another workaround?

**A:** No, enabling or disabling this group policy has no effect on the vulnerable part of Troubleshooter functionality, so it is not a viable workaround.

**Q:** Is blocking MSDT using technologies such as Windows Defender Application Control (WDAC) equivalent to removing MSDT handler “HKEY\_CLASSES\_ROOT\\ms-msdt” a viable workaround?

**A:** Blocking MSDT will prevent all MSDT-based Windows Troubleshooters from launching, such as the Network Troubleshooter, and the Printer Troubleshooter. The recommended workaround disables support for clicking on MSDT links and users can continue to use the familiar Windows Troubleshooters.

**Q** : What Windows versions require the workaround?

**A** : The MSDT URL protocol is available in Windows Server 2019 & Windows 10 version 1809 and later supported versions of Windows. The registry key mentioned in the workaround section will not exist in earlier supported versions of Windows, so the workaround is not required.

Guidance for CVE-2022-30190 Microsoft Support Diagnostic Tool Vulnerability

Organizations must ensure their kubelets and related APIs aren’t inadvertently exposed or lack proper access control, offering an easy access point for malicious actors.

Kubernetes clusters provide a scalable and resilient backbone to many modern Internet-facing applications. However, if adversaries can access the nodes in those clusters, they essentially take over your infrastructure. They can compromise the integrity of your systems and hijack the infrastructure and use it for their own purposes.

Recent data from Shodan shows 243,469 Kubernetes clusters that are publicly exposed. These clusters also exposed port 10250, used by the kubelet (the agent that runs on each node and ensures that all containers are running in a pod) as a default setting. Attackers could potentially use the kubelet API as an entry point in targeting Kubernetes clusters to mine for cryptocurrency.

Trend Micro researcher Magno Logan looked at how cybercriminals could abuse these clusters and exposed kubelet ports.

First, there is the problem of sensitive information leakage by returning data on the running pods on the node.

In addition, since the kubelet API is exposed, there is another endpoint _/run_ that would allow an attacker to execute commands inside the running pods of the cluster just by sending a _POST_ request to the specific pods and using the parameter _cmd_ to execute the desired shell commands. Trend Micro says threat actor TeamTNT performed multiple _/run_ commands in just this manner to compromise multiple clusters last year. This technique can make things easier for attackers to take over clusters, Logan says in the report.

Logan called it "very concerning" that hackers could use the kubelet API as an entry point when targeting Kubernetes clusters.

"Those 600 kubelets we've found to be completely exposed and without authentication or authorization could easily be compromised via simple API requests," he said. "That would allow an attacker to execute commands on the pods running inside that node, most of the time to mine cryptocurrencies."

**Exposed Kubelets Leave Door Open to Malicious Actors**

According to Michael Isbitski, director of cybersecurity strategy for Sysdig, when Kubernetes clusters or kubelets are improperly exposed or don't enforce proper access control, it leaves the door open for a wide range of malicious activity.

"Attackers can potentially harvest sensitive data being transmitted within the cluster, spin-up new workloads, reconfigure elements of a node, disable access controls, erase audit trails, add vulnerable dependencies, bootstrap malicious cryptominers, and more," he says.

Isbitski notes that many Kubernetes configurations are secure by default with current platform offerings, but some organizations may be sitting on old or misconfigured deployments.

He points out organizations also sometimes inadvertently override secure defaults to get a cluster to an operational state without understanding the potential security risks.

"We've seen issues with vulnerabilities in runtime components, which can result in container escapes and lateral movement within networks if attackers are successful in their exploitation attempts," he says.

**Practice Defense In-Depth, Zero Trust**

Matt Dupre, director of software engineering at Tigera, a provider of security and observability for containers, Kubernetes, and cloud, points out that sufficiently privileged access to the kubelet amounts to a complete compromise of that host and potentially any other workloads running on it.

Access to the Kubernetes API has the same potential impact: Admin access essentially provides complete control of the cluster and everything in it.

He notes that while the security risk is significant, an overwhelming majority of the clusters that accepted connections from the Internet rejected the requests due to lack of authentication or authorization.

"Given that, there are two concerns: firstly, that you fall in that misconfigured 613 clusters, or that a new critical vulnerability that bypasses authn or authz is found, and this would be a very significant vulnerability," Dupre says. "Organizations' internal APIs are probably a bigger worry in practice."

He advises practicing defense in depth by following zero-trust principles and not allowing connections to your kubelets from unknown sources, such as the Internet.

"Additionally, you could port-scan your infrastructure and investigate any responses," he adds. "Keeping careful control of access tokens is always important — they should never be published, and you should have processes in place to ensure that they and other secrets are stored properly."

**Avoid Exposing the Kubelet Default Port**

As a basic kubelet security practice, Logan says organizations shouldn’t expose their kubelet port (10250 by default) to the Internet.

"If you need to do that, at least enable kubelet authentication and authorization on the kubelet API to avoid attackers being able to perform requests to the API and receive the 401 – Unauthorized response," he adds.

Mark Lambert, vice president of products at ArmorCode, an application security provider, says when deploying these types of systems, take a "zero-trust mindset" and remember that the default configurations are usually set up for ease of use, not security.

"This means you need to pay close attention to configuration files, disable features you are not using, change default ports, and minimize information leakage so that hackers cannot gain insight that could provide them another point of attack," he says.

Finally, all this needs to be operationalized as part of your application security program, and development teams must be engaged early, as they play a key role in building security into the design of the application from the start.

Besides enabling the kubelet authentication and authorization on the kubelet API, Logan advises restricting the kubelet permissions via the least privilege principle and periodically rotating the kubelet certificates to reduce the attack surface.

"Organizations should also investigate tools for runtime protection such as Falco to prevent and alert when there are suspicious execution happening inside their containers," he says.

**Constantly Analyze IaaC, Monitor Clusters in Runtime**

Isbitski says native capabilities and tooling from cloud providers and Kubernetes platform providers can provide a starting point for keeping kubelets protected.

He adds that security teams must continuously analyze the infrastructure-as-code used to configure and operate clusters, scan dependencies used by workloads, and monitor clusters in runtime to detect malicious activity, such as when an attacker attempts unauthorized access to the Kubernetes APIs.

"Appropriate access control should also be implemented at multiple points of a cluster," he says. "Native capabilities like Kubernetes network policy also help with restricting communication within a cluster and enforce zero trust principles."

Isbitski points out the Kubernetes control plane is also multilayered when working with managed Kubernetes.

In those scenarios, security teams should also continuously validate the cloud tenant configurations, along with IAM policies, for misconfigurations and excessive permissions.
