Windows Enterprise Privilege Escalation: Vectors Uncovered in Penetration Tests
A deep analysis of unquoted service paths, weak folder permissions, token impersonation, and automated escalation defense.
Moving from Low-Privilege to SYSTEM
Gaining initial foothold access as a standard domain user is merely the starting line for an ethical hacker or adversary. The immediate objective is escalating privileges to local administrator or SYSTEM.
Common Misconfigurations Found in Enterprise Audits
Unquoted Service Paths with write access to parent folders.
Weak service binary permissions allowing non-admin users to replace executables.
AlwaysInstallElevated registry keys enabling standard users to execute MSI packages with SYSTEM rights.
Remediation and Endpoint Auditing
Deploy automated PowerShell auditing scripts during system image builds to verify that all third-party services are installed in protected directories (`C:\Program Files`) with properly quoted paths and strict ACLs.
