How to Safeguard From macOS App Sandbox Vulnerability
Redmond giant Microsoft has uncovered a vulnerability in Apple’s macOS. The vulnerability, now identified as CVE-2023-26706, could allow specially crafted codes to escape the App Sandbox and run unrestricted on a Mac. Microsoft shared its findings with Apple in October 2021 last year. They did it through Coordinated Vulnerability Disclosure (CVD) via Microsoft Security Vulnerability Research (MSVR).
Apple engineers worked on the bug and released a security update earlier this year to fix the App Sandbox vulnerability. Microsoft uncovered the bug in a blog post when Apple successfully fixed it. Stay tuned to the article if you are a macOS user and want to safeguard yourself from the App Sandbox vulnerability. Here we have explained the steps you can take to keep your Mac safe from this bug.
What is App Sandbox in macOS?
App Sandbox is Apple’s access control technology. App developers must adopt App Sandbox before they submit their apps to Mac App Store. The App Sandbox enforces a customizable rule to an app process. It includes reading or writing specific files. It also restricts processes from accessing system resources and user data. When an app gets compromised, App Sandbox minimizes the damage.
App Sandbox Vulnerability
Microsoft security researchers find that a specially crafted code can easily bypass the App Sandbox rules. A hacker can use this vulnerability to get elevated privileges on the affected device or install additional payloads. Microsoft security team found this vulnerability when researching potential ways to run and detect malicious macros in Microsoft Office on Mac.
Microsoft Word can read or write files with the “~$” prefix for backward compatibility. The team found that it was possible to escape the sandbox with the help of the “~$” prefix. Hackers could have leveraged Launch services in macOS to run an open -stdin command on a specially crafted Python file with the “~$” prefix. The research also discovered that the bug could have bypassed macOS built-in baseline security features, compromising system, and user data.
