CVE-2023-26238

Defense disabling via crafted named-pipe commands

Published Oct 5, 2023 · Updated Sep 19, 2024

Protection bypass in WatchGuard EPDR and Panda AD360 8.00.22.0009 and earlier allows local users to disable defensive capabilities. The protection agent accepts crafted interprocess-communication commands over a named pipe without enforcing anti-tamper controls. Local access is required, and exploitation can enable or disable endpoint defenses rather than execute code or expose data.
