⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains SYSTEM/root privileges, enabling complete system compromise, data theft, persistence installation, and lateral movement.
Likely Case
Local authenticated users escalate to administrative privileges, allowing unauthorized software installation, configuration changes, and access to sensitive data.
If Mitigated
With proper access controls and patching, impact is limited to denial of service or minimal privilege escalation within user context.
🎯 Exploit Status
Requires local authenticated access and knowledge of search path manipulation techniques.
🛠️ Fix & Mitigation
✅ Official Fix
