⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining SYSTEM/administrator privileges, data exfiltration, ransomware deployment, and lateral movement across the network.
Likely Case
Remote code execution leading to data theft, credential harvesting, and installation of backdoors or malware on vulnerable servers.
If Mitigated
Limited impact due to network segmentation, application allowlisting, and proper access controls preventing successful exploitation.
🎯 Exploit Status
