📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Local attacker gains SYSTEM/administrator privileges, enabling complete system compromise, data theft, persistence installation, and lateral movement.
Likely Case
Malicious insider or compromised standard user account escalates to administrative privileges to bypass security controls.
If Mitigated
With proper access controls and least privilege principles, impact is limited to authorized users only.
🎯 Exploit Status
Requires local authenticated access. Based on CWE-269 (Improper Privilege Management), exploitation likely involves manipulating installer processes or permissions.
