📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Local privilege escalation leading to complete system compromise, data exfiltration, and lateral movement within the network.
Likely Case
Local user gains elevated privileges to access sensitive credentials and secrets stored in the Secret Server.
If Mitigated
Limited impact with proper access controls, network segmentation, and monitoring in place.
🎯 Exploit Status
Requires local access to the system but exploitation appears straightforward once access is obtained.
