⚠️ Risk & Real-World Impact
Worst Case
An attacker with initial access could gain SYSTEM/administrator privileges, potentially leading to complete system compromise, credential theft, and lateral movement within the network.
Likely Case
An authenticated user could elevate their privileges to administrator level, allowing them to install programs, modify system settings, and access sensitive data.
If Mitigated
With proper privilege separation and least privilege principles, the impact is limited to the specific user account being exploited rather than full system compromise.
🎯 Exploit Status
Requires authenticated access and local execution. No public exploit code available at this time based on the CVE description.
