Technical details

An incorrect default permissions vulnerability (CWE-276) exists in Fuji Electric Pupsman versions prior to 3.9.0. The software's installation folder is configured with insecure access control lists (ACLs), allowing low-privileged local users to write files into the directory. An attacker can exploit this by placing a malicious executable or DLL in the installation folder. Because the application or its associated services run with elevated privileges, this results in arbitrary code execution with SYSTEM authority. The issue is resolved in version 3.9.0.
