Technical details

An arbitrary code execution vulnerability exists in Hirschmann Industrial HiVision versions 05.0.00 through 08.3.01. The flaw is triggered during the processing of project files; if a user with administrative privileges opens a specially crafted file, the application fails to properly validate the contents, leading to code execution within the context of the HiVision process. This is a local attack vector requiring user interaction (UI:R). The vulnerability is addressed in version 08.3.02. Note: Some advisory sources also mention a related privilege escalation path via crafted packets to the HiSecOS web server component.
