CVE-2022-31790Public exploitNetwork attack vector

Authentication-settings disclosure via unsanitized XPath query

Published Sep 6, 2022 · Updated Aug 3, 2024

XPath injection in WatchGuard Fireware OS 12.0 through 12.8 allows remote attackers to read authentication server settings. The wgcgi VPN login handler inserts the unauthenticated fw_domain value into an XPath query over the XML configuration without validation or sanitization. An exposed HTTPS login endpoint is sufficient; the resulting timing oracle reveals configuration data, including stored authentication-server credentials when present.
