CVE-2022-22244Network attack vector

Unauthenticated information disclosure via raw XPath forwarding

Published Oct 18, 2022 · Updated May 9, 2025

XPath injection in J-Web in Juniper Networks Junos OS allows remote attackers to expose confidential data through a crafted POST request. The interface.php endpoint reads the raw request body, blocks only one command substring, and forwards the remainder to the send_raw() XPath channel. No authentication or user interaction is required; the published impact is limited to partial confidentiality loss and depends on chaining with other unspecified flaws.
