A macOS and iOS bug could trigger a new wave of exploits

While the immediate issues stemming from a new class of bugs that can beat macOS and iOS’s strict code signing have been patched, researchers are wary that there are more to come.

Apple is known to be extremely strict when it comes to code signing on iOS, with only apps that are cryptographically signed by a developer certificate trusted enough to run on the operating system. MacOS becoming more and more similar to iOS, stricter enforcement of code signing has also been adopted for added security.

However, in a disclosure Tuesday by the security outfit Trellis, there is a “large new class of bugs” that an attacker could use to bypass code signing and allow code execution in macOS and iOS. This can lead to application escalation and exit from the sandbox.

Such code would theoretically have access to sensitive information stored on the device, such as message history, location data, and images, among other things.

Initial discovery

The researchers behind the disclosure were intrigued by September 2021 research from Citizen Lab, which detailed the “ForcedEntry” zero-click exploit for iOS that was used to infect an iPhone with the Pegasus malware. After analyzing the details of a sandbox escape, Trellix became interested in how it could dynamically execute code in another process, which bypassed code signing.

Although Apple removed functionality that allowed an exploit to be used in this way, as well as adding new mitigations, researchers found that the mitigations could be circumvented.

Specifically, an attacker would use unlimited methods to flush a large deny list that would prevent the use of specific classes and methods. With the empty lists, the attacker would be free to use the previously employed methods without the limitations in the way.

With this discovery, a “vast range of potential vulnerabilities” may have been opened up using the technique, which the team is “still exploring”.

Vulnerabilities found

The first class vulnerability to be discovered was in “coreduetd”, a process that monitors the behavior of a device. Using code execution in a process with “appropriate rights” in Messages or Safari, a malicious “NSPredicate” could have been sent, with code executable with the process’s privileges.

Since the process runs as root in macOS, this would grant the attacker access to the user’s calendar, address book and photos, Trellix claims.

A similar issue was discovered attacking the “contextstored” related to “CoreDuet” with the use of a vulnerable XPC service that could execute code from a process that has more access to device functionality.

The “appstored” and “appstoreagent” daemons on macOS had vulnerable XPC services, which could be used to exploit the same vulnerabilities. Ultimately, this could have led to the installation of “arbitrary apps, potentially even including system apps”.

Trellix says the vulnerabilities “represent a significant violation of the macOS and iOS security model which relies on individual applications having precise access to the subset of resources they need and querying higher privileged services to obtain something else.” .

Services that accept NSPredicate arguments but do not adequately verify them can allow malicious actors to execute code “to overcome process isolation and directly access far more resources than should be allowed.”

How to protect yourself

As in many other situations where a vulnerability has been responsibly disclosed, a patch has already been applied to operating systems. The issues were resolved with the release of macOS 13.2 and iOS 16.3.

“We would like to thank Apple for working quickly with Trellix to resolve these issues,” the company’s disclosure concludes.

Indeed, all that is required to fix the first vulnerability found is to update the operating systems to macOS 13.2, iOS and iPadOS 16.3, or later.

Operating systems should be updated regularly or set to run automatically, simply because each usually includes security fixes, as well as performance improvements and new features.

As researchers dig deeper into this type of vulnerability, there may be others along the way. Keeping your operating system up to date can be one of the best things you can do to mitigate them as they appear.
