Microsoft on Wednesday drop light on a now patched security vulnerability affecting Apple’s working programs that, if effectively exploited, could allow attackers to escalate product privileges and deploy malware.
“An attacker could just take edge of this sandbox escape vulnerability to achieve elevated privileges on the impacted machine or execute destructive commands like setting up extra payloads,” Jonathan Bar Or of the Microsoft 365 Defender Research Crew stated in a generate-up.
Tracked as CVE-2022-26706 (CVSS rating: 5.5), the security vulnerability impacts iOS, iPadOS, macOS, tvOS, and watchOS and was fastened by Apple in May possibly 2022.

Calling it an accessibility issue influencing the LaunchServices (launchd) element, the tech giant mentioned that “A sandboxed course of action may perhaps be capable to circumvent sandbox limitations,” adding it mitigates the issue with supplemental constraints.
When Apple’s App Sandbox is developed to tightly regulate a 3rd-party app’s obtain to method means and person information, the vulnerability makes it doable to bypass these constraints and compromise the machine.
“The sandbox’s main functionality is to include damage to the technique and the user’s information if the user executes a compromised application,” Apple describes in its documentation.
“Even though the sandbox will not avoid attacks towards your app, it does cut down the hurt a profitable attack can trigger by restricting your app to the least set of privileges it needs to purpose effectively.”
Microsoft reported it learned the flaw throughout its attempts to figure out a way to escape the sandbox and execute arbitrary instructions on macOS by concealing the malicious code in a specifically crafted Microsoft Place of work macro.
Exclusively, the tweet-sized evidence-of-concept (PoC) devised by the tech giant leverages Launch Companies as a means to operate an open command — a utility used to open information and launch applications — on a Python payload made up of rogue directions.
But it can be really worth noting that any file dropped by a sandboxed app is immediately connected to the “com.apple.quarantine” prolonged attribute so as to cause a prompt necessitating explicit user’s consent prior to execution.
This constraint, having said that, can be eradicated by employing the -stdin alternative for the open command affiliated with the Python exploit file.
“–stdin bypassed the ‘com.apple.quarantine’ extended attribute restriction, as there was no way for Python to know that the contents from its regular enter originated from a quarantined file,” Bar Or reported.
