CVE-2022-36663Public exploitNetwork attack vector

Unauthenticated internal network probing via request_uri fetching

Published Sep 6, 2022 · Updated Aug 3, 2024

Blind SSRF in Gluu OxAuth before 4.4.1 allows remote attackers to make server-side requests via a crafted request_uri parameter. JwtAuthorizationRequest passes the supplied URI to queryRequest for retrieval without first requiring client registration or rejecting blocked destinations. The authorization endpoint requires no prior privileges or user interaction, and the blind response channel exposes outbound reachability and internal port state rather than response bodies.
