How the CVE Works:
CVE-2025-31232 is a sandbox escape vulnerability in macOS due to improper logic checks in the app sandboxing mechanism. A malicious app, despite being sandboxed, can bypass restrictions and access sensitive user data stored outside its designated container. The flaw arises from insufficient validation of file access permissions, allowing crafted system calls to traverse directories improperly. Apple addressed this by hardening sandbox policy checks in macOS Ventura 13.7.6, Sonoma 14.7.6, and Sequoia 15.5.
DailyCVE Form:
Platform: macOS
Version: Ventura <13.7.6, Sonoma <14.7.6, Sequoia <15.5
Vulnerability: Sandbox Escape
Severity: Critical
Date: 2025-05-12
Prediction: Patch expected by 2025-06-10
What Undercode Say:
Exploitation:
- Craft a malicious app with enments to exploit weak sandbox checks.
- Use `open()` syscall with path traversal to access restricted files.
- Leverage `posix_spawn()` to execute arbitrary code outside the sandbox.
Protection:
- Update to macOS Ventura 13.7.6, Sonoma 14.7.6, or Sequoia 15.5.
2. Enable System Integrity Protection (SIP): `csrutil enable`.
3. Restrict app permissions via `sandbox-exec`:
sandbox-exec -n no-network /path/to/app
Detection:
1. Scan for suspicious file access logs:
log show --predicate 'eventMessage contains "sandbox" AND process == "kernel"' --last 7d
2. Monitor app enments:
codesign -dv --enments :- /Applications/SuspiciousApp.app
Mitigation Script:
!/bin/bash Disable vulnerable apps pending update sudo spctl --master-disable sudo chmod -R 750 /Applications/.app
Analytics:
- Attack Vector: Local (low complexity)
- Impact: Confidentiality breach (high)
- Exploitability: Likely (PoC expected soon)
- Patch Priority: Immediate
