CVE-2022-34758

Watchdog disablement via improperly validated input

Published Jul 13, 2022 · Updated Sep 17, 2024

Improper input validation in Schneider Electric Easergy P5 before V01.401.102 allows local users to disable the device watchdog. Schneider Electric identifies improper input validation as the cause but has not disclosed the affected input, interface, or exact validation error. Privileged user credentials and local access are required; successful exploitation leaves the relay without its watchdog function.
