CVE-2023-5961Network attack vector

User-driven device operations via forged web requests

Published Dec 23, 2023 · Updated Nov 27, 2024

CSRF in Moxa ioLogik E1200 Series firmware 3.3 and earlier allows remote attackers to perform operations via forged requests. The embedded web server accepts an attacker-induced client request as authentic, but Moxa has not disclosed the affected handler or missing validation step. Exploitation requires client interaction while the device is reachable, and the operation runs with the victimized user's authority.
