Malwarebytes AdwCleaner 8.4.0 runs as Administrator and performs an insecure file delete operation on C:\AdwCleaner\Logs\AdwCleaner_Debug.log in which the target location is user-controllable, allowing a non-admin user to escalate privileges to SYSTEM via a symbolic link.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
