How the CVE Works:
CVE-2025-24281 is a critical vulnerability in macOS Sequoia (pre-15.4) that allows unauthorized apps to bypass data protection mechanisms and access sensitive user data. The flaw stems from improper access controls in the system’s sandboxing implementation, enabling malicious applications to exploit insufficient permission checks. Attackers could leverage this to read cached credentials, keychain entries, or private app data without user consent. The vulnerability is resolved in macOS 15.4 via enhanced isolation policies.
DailyCVE Form:
Platform: macOS
Version: <15.4
Vulnerability: Data exposure
Severity: Critical
Date: 04/04/2025
What Undercode Say:
Exploitation:
Proof-of-concept to leak sensitive data (hypothetical) osascript -e 'tell app "System Events" to get properties of every process'
Detection:
Check macOS version sw_vers -productVersion
Mitigation:
Immediate update command softwareupdate --install --all
Code Analysis:
The flaw likely involves mishandled `enments` in app sandbox profiles. Example vulnerable enment:
<key>com.apple.private.tcc.allow</key> <array><string>kTCCServiceAppleEvents</string></array>
Protection:
1. Enforce strict sandboxing via custom profiles:
/usr/bin/sandbox-exec -f custom.sb /path/to/app
2. Monitor suspicious data access:
fs_usage -w -f filesys | grep "private"
