⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full SYSTEM privileges on the compromised system, enabling complete control, data theft, persistence mechanisms, and lateral movement capabilities.
Likely Case
Privileged attackers already on the system escalate to SYSTEM to bypass security controls, install malware, or access protected resources.
If Mitigated
With proper access controls and monitoring, impact is limited to isolated systems with rapid detection and containment.
🎯 Exploit Status
Exploitation requires local authenticated access but appears straightforward based on vulnerability description.
