CVE-2026-89025
Hirschmann HiOS Switch Platform devices contain a denial-of-service vulnerability in the integrated web server due to missing validation of HTTP(S) content. A remote unauthenticated attacker can send a specially crafted HTTP(S) request to a specific endpoint that is processed incorrectly, causing the device to perform an unintended reboot and resulting in a temporary denial-of-service condition. This vulnerability has been addressed in versions 07.1.12, 08.7.10, 09.0.13, 09.3.03, 10.3.08, and 10.5.00.
