- Severity: CVSS 7.3 (High), CNA
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total

- Published: 2026-04-03 · Updated: 2026-05-25

## Affected

- Belden Hirschmann Industrial HiVision: through 08.1.03

## Description

Hirschmann Industrial HiVision version 08.1.03 prior to 08.1.04 and 08.2.00 contains a vulnerability in the execution of user-configured external applications that allows a local attacker to execute arbitrary binaries. Due to insufficient path sanitization, an attacker can place a malicious binary in the execution path of a configured external application, causing it to be executed instead of the intended application. This can result in execution with elevated privileges depending on the context of the external application.
