Critical macOS Sandbox Vulnerability (CVE-2024-54498) and Its Implications

Overview of CVE-2024-54498

CVE-2024-54498 is a significant security vulnerability identified in macOS, allowing applications to escape the confines of the macOS Sandbox—a security feature designed to restrict apps from accessing unauthorized system resources. This flaw arises from a path handling issue that was inadequately validated, enabling malicious applications to bypass sandbox restrictions and potentially access sensitive user data or execute unauthorized actions on the system. citeturn0search16

Technical Details

The vulnerability resides in the sharedfilelistd process, which manages shared file lists in macOS. Due to improper validation of file paths, an attacker can craft a malicious application that exploits this flaw to break out of its sandbox environment. Once outside the sandbox, the application gains elevated privileges, allowing it to interact with system files and other applications without restriction. citeturn0search18
