Technical details

The vulnerability is classified as an Untrusted Search Path (CWE-426) issue within Hirschmann Industrial HiVision. It stems from insufficient path sanitization when the software executes user-configured external applications. A local attacker with low privileges can exploit this by placing a malicious binary in a directory that is searched before the legitimate application's path. If a user or the system triggers the external application, the malicious binary is executed instead. Depending on the service context, this can lead to arbitrary code execution with elevated privileges. The issue is addressed in version 08.1.04 and was also fixed in the 08.2.x branch.
