macOS, Sandbox Escape Vulnerability, CVE-2025-24108 (Critical)

How the Mentioned CVE Works:

CVE-2025-24108 is a critical sandbox escape vulnerability in macOS Sequoia versions prior to 15.3. The flaw arises due to insufficient sandbox restrictions, allowing malicious applications to bypass macOS’s built-in sandboxing mechanisms. This enables unauthorized access to protected user data, such as sensitive files, keychain items, or other resources typically isolated by the sandbox. The vulnerability leverages improper handling of system calls or resource permissions, granting elevated access to malicious apps. Apple addressed this issue in macOS Sequoia 15.3 by implementing stricter sandbox policies and additional validation checks.

DailyCVE Form:

Platform: macOS
Version: Sequoia (< 15.3)
Vulnerability: Sandbox Escape
Severity: Critical
Date: 01/27/2025

What Undercode Say:

Exploitation:

1. Exploit Code: Malicious apps can use crafted system calls to bypass sandbox restrictions. Example:

   // Pseudo-code for sandbox escape
   void exploit_sandbox() {
   int fd = open("/protected/data", O_RDWR);
   if (fd != -1) {
   // Access protected data
   read(fd, buffer, sizeof(buffer));
   }
   }
   

2. Exploit Command: Use `lldb` to debug and manipulate sandboxed processes:

   lldb -p <sandboxed_process_id>
   

3. Exploit URL: Research sandbox escape techniques at Sandbox Escape Techniques.

Protection:

1. Patch: Update to macOS Sequoia 15.3 or later.

2. Command: Verify macOS version:

sw_vers

3. Code: Implement additional sandbox checks in apps:

// Example of enhanced sandbox validation
if (is_sandboxed()) {
enforce_strict_policies();
}

4. URL: Download the latest macOS update from Apple Support.

Analytics:

1. CVSS 4.0: Base Score: 9.8 (Critical), Vector: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
2. Affected Systems: macOS Sequoia versions prior to 15.3.
3. Mitigation: Enable automatic updates and restrict app installations to trusted sources.
