CVE-2022-22511Network attack vector

Authenticated script execution via reflected configuration input

Published Mar 9, 2022 · Updated Sep 17, 2024

Reflected XSS in WAGO controllers and panels running FW16 through FW21 allows remote authenticated users to execute scripts in a visitor's browser. Various WBM configuration pages reflect attacker-supplied input into generated web content without neutralizing browser-executable markup. Exploitation requires a valid device login and a later WBM visit from a PC, exposing that browser context to malicious code and confidential-information access.
