Technical details
An Untrusted Search Path vulnerability (CWE-426) exists in B&R Industrial Automation GmbH APROL versions prior to R 4.4-01P5. The application fails to properly validate or sanitize the search path used to locate and load external resources or libraries. A local attacker with file system access can exploit this by placing a malicious binary or library in a directory that is searched before the legitimate one. Successful exploitation allows for arbitrary code execution with the privileges of the APROL process. The issue is resolved in version R 4.4-01P5.
