⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with SYSTEM privileges, allowing installation of persistent malware, data theft, and complete control over the affected system.
Likely Case
Local privilege escalation leading to administrative access on the system, enabling further lateral movement and persistence mechanisms.
If Mitigated
Limited impact with proper application whitelisting and user privilege restrictions preventing DLL execution from untrusted paths.
🎯 Exploit Status
Requires local access and ability to place malicious DLLs in search paths before installer execution.
