Improper access control in Emerson PAC Machine Edition 9.00 and earlier allows local users to alter or delete stored project data. Project data is stored in a directory whose access control lists grant unauthorized filesystem access instead of restricting writes to intended users. Exploitation requires local low-privilege access and user interaction; reported impact is limited to project integrity and availability.
