CVE-2023-39446Network attack vector

Authenticated action execution via crafted URLs

Published Sep 18, 2023 · Updated Sep 24, 2024

Cross-site request forgery in Socomec MODULYS GP Web Firmware 01.12.10 allows remote authenticated users to execute device actions. The user-management web interface exposes header information used to construct action URLs, but Socomec has not disclosed the missing request-validation check. Exploitation requires low-privileged access and a legitimate logged-in user to follow the crafted URL, after which actions run with that user's authority.
