📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative credentials, leading to complete system compromise, data theft, or lateral movement across the network.
Likely Case
Local users escalate privileges or access sensitive systems using stolen credentials.
If Mitigated
Limited to credential exposure without successful exploitation due to access controls.
🎯 Exploit Status
Exploitation requires local access but is straightforward once credentials are accessed.
