How the CVE Works
CVE-2025-24232 is a critical vulnerability in macOS (Ventura, Sequoia, Sonoma) caused by improper state management, allowing malicious apps to bypass file access restrictions. Attackers exploit this flaw by manipulating system processes to gain unauthorized read/write access to sensitive files, potentially leading to data theft or privilege escalation. The vulnerability stems from insufficient sandboxing enforcement, enabling apps to traverse directories beyond intended permissions. Apple patched it in macOS Ventura 13.7.5, Sequoia 15.4, and Sonoma 14.7.5.
DailyCVE Form

Vulnerability: Arbitrary file access
Severity: Critical
Date: 04/07/2025
What Undercode Say:
Exploitation Analysis
- Exploit Vector: Malicious app abuses flawed state handling to bypass
com.apple.security.app-sandbox.
2. PoC Code:
let exploit = FileManager.default.contents(atPath: "/private/var/db/sudo/")
3. Post-Exploit: Attacker exfiltrates sensitive data (e.g., sudo logs, keychains).
Protection Commands
1. Patch Verification:
sw_vers -productVersion
Ensure output is ≥13.7.5 (Ventura), ≥15.4 (Sequoia), or ≥14.7.5 (Sonoma).
2. Sandbox Hardening:
sudo defaults write /Library/Preferences/com.apple.security.libraryvalidation.plist DisableLibraryValidation -bool false
3. Log Monitoring:
log stream --predicate 'eventMessage contains "fileaccess"'
Mitigation Script
!/bin/bash if [[ $(sw_vers -productVersion) < "13.7.5" ]]; then echo "Vulnerable. Update immediately." else echo "Patched." fi
Indicators of Compromise (IoC)
- Unusual file access from non-system apps (
/private/var,/Library/Keychains).
– `sandboxd` logs showing `deny file-read-data` for trusted apps.
