📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Local authenticated user gains full administrator privileges, potentially compromising the entire system, installing malware, accessing sensitive data, and bypassing security controls.
Likely Case
Malicious insider or compromised user account elevates privileges to administrator, allowing lateral movement, persistence establishment, and data exfiltration.
If Mitigated
With proper file permissions and monitoring, exploitation attempts are detected and blocked before privilege escalation occurs.
