⚠️ Risk & Real-World Impact
Worst Case
Local attacker gains SYSTEM/administrator privileges, enabling complete system compromise, data theft, malware persistence, and lateral movement.
Likely Case
Local user or malware with limited privileges escalates to administrator rights to install additional malware, modify system settings, or bypass security controls.
If Mitigated
With proper patching and least privilege principles, impact is limited to local system only with no network propagation.
🎯 Exploit Status
TOCTOU vulnerabilities require precise timing but are well-understood attack patterns. Requires local execution on target system.
