CVE-2022-22243Network attack vector

Authenticated data exposure via XPath command injection

Published Oct 18, 2022 · Updated May 9, 2025

XPath injection in Juniper Networks Junos OS J-Web allows remote authenticated users to expose data by injecting XPath commands. J-Web improperly incorporates attacker-controlled input into its XPath stream, permitting an added XPath command to alter query evaluation. Access requires authentication to the network-reachable management interface; Juniper reports only partial confidentiality loss, with further impact dependent on chaining with unspecified vulnerabilities.
