⚠️ Risk & Real-World Impact
Worst Case
Attacker gains full SYSTEM privileges, enabling complete system compromise, data theft, malware persistence, and lateral movement across the network.
Likely Case
Local attacker escalates privileges to install additional malware, steal credentials, or bypass security controls on the compromised system.
If Mitigated
With proper file permissions and monitoring, exploitation attempts would be detected and prevented before SYSTEM execution occurs.
🎯 Exploit Status
Requires local access and ability to replace the binary file. No authentication bypass needed if attacker already has user-level access.
