CVE-2022-22162

Low-privileged escalation via CLI error message

Published Jan 19, 2022 · Updated Sep 16, 2024

Information exposure in Junos OS CLI allows locally authenticated low-privilege users to elevate to the highest-privilege J-Web user via crafted errors. The CLI generates error messages that expose sensitive information used to assume the privileges of another user currently logged in through J-Web. Exploitation requires local authenticated access, a configured J-Web service, and user interaction; Juniper reports potential full device compromise.
