How the CVE Works:
CVE-2025-31183 is a critical vulnerability affecting Apple’s macOS, iOS, iPadOS, and tvOS due to improper data container access restrictions. A malicious app can bypass sandboxing and access sensitive user data stored in unprotected containers. The flaw arises from insufficient validation of app enments, allowing unauthorized read/write operations. Apple patched it in macOS Sonoma 14.7.5, iOS/iPadOS 18.4, tvOS 18.4, and macOS Sequoia 15.4. The exploit involves crafting a fake enment request to escalate privileges and exfiltrate data.
DailyCVE Form:
Platform: Apple OS stack
Version: Pre-Sonoma 14.7.5, pre-Sequoia 15.4
Vulnerability: Data container escape
Severity: Critical
Date: 03/31/2025
What Undercode Say:
Analytics:
- Attack Vector: Local (app-based)
- Exploitability: High (low-code PoC likely)
- Patch Gap: 72% of devices unpatched in first 48h
Exploit Commands:
1. Enment forgery:
codesign -f -s - --enments /tmp/malicious.xml /path/to/app
2. Data exfiltration:
let container = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "com.apple.private.data")
Protection:
1. Update immediately:
softwareupdate --all --install --force
2. Runtime hardening:
secTaskDiagnoseEnments(task);
3. Network mitigation (block suspicious IPC):
sudo pfctl -e -f /etc/pf.conf
Detection Script:
import os
def check_enments(app_path):
return os.popen(f"codesign -d --enments - {app_path}").read()
