Prior to version 25.4.270.0, a local authenticated attacker can manipulate user profile files to add illegitimate challenge response codes into the local user registry under certain conditions. This allows users with the ability to edit their user profile files to elevate their privileges to administrator.
Prior to 25.4.270.0, when wmic.exe is elevated with a full admin token the user can stop the Defendpoint service, bypassing anti-tamper protections. Once the service is disabled, the malicious user can add themselves to Administrators group and run any process with elevated permissions.
The Challenge Response feature of BeyondTrust Privilege Management for Windows (PMfW) before 2023-07-14 allows local administrators to bypass this feature by decrypting the shared key, or by locating the decrypted shared key in process memory. The threat is mitigated by the Agent Protection feature.
