Adobe Photoshop Elements 8.0 installs the Adobe Active File Monitor V8 service with an insecure security descriptor, which allows local users to (1) stop the service via the stop command, (2) execute arbitrary commands as SYSTEM by using the config command to modify the binPath variable, or (3) restart the service via the start command.
