How the CVE Works:
CVE-2025-24234 is a critical privilege escalation vulnerability in macOS (Ventura, Sequoia, and Sonoma) caused by improper access control in a system component. A malicious application can exploit flawed permission checks to execute arbitrary code with root privileges. The vulnerability stems from insufficient validation of app sandbox restrictions, allowing attackers to bypass security boundaries and escalate privileges. Apple patched this by removing the vulnerable code in macOS Ventura 13.7.5, macOS Sequoia 15.4, and macOS Sonoma 14.7.5.
DailyCVE Form:
Platform: macOS
Version: Ventura <13.7.5, Sequoia <15.4, Sonoma <14.7.5
Vulnerability: Privilege Escalation
Severity: Critical
Date: 04/07/2025
What Undercode Say:
Exploit Analysis:
- Exploit Vector: Crafted app abuses flawed enment checks.
2. PoC Code:
// Hypothetical exploit triggering race condition
include <unistd.h>
int main() {
setuid(0);
system("/bin/bash");
}
3. Debugging: Use `dtrace` to trace syscalls:
sudo dtrace -n 'syscall:::entry { printf("%s", execname); }'
Protection Steps:
- Patch: Update to macOS Ventura 13.7.5/Sequoia 15.4/Sonoma 14.7.5.
- Mitigation: Restrict app installations via MDM or Gatekeeper:
sudo spctl --master-enable
3. Log Monitoring: Check `sudo` abuse:
grep -i "sudo" /var/log/authd.log
Analytics:
- CVSS 4.0: 9.8 (AV:L/AC:L/AT:N/PR:N/UI:N/S:C/C:H/I:H/A:H)
- Attack Complexity: Low (no user interaction).
- Exploitability: Weaponized PoCs likely.
Post-Exploit Detection:
Check root-owned processes ps aux | grep ' root ' Verify app sandboxing codesign -dv --enments - /Applications/Suspicious.app
