https://bugzilla.suse.com/show_bug.cgi?id=1217804 Bug ID: 1217804 Summary: VUL-0: CVE-2023-47106: traefik: incorrect processing of fragment in the URL leads to authorization bypass Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.6 Hardware: Other URL: https://smash.suse.de/issue/386931/ OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Security Assignee: alexandre.vicenzi@suse.com Reporter: smash_bz@suse.de QA Contact: security-team@suse.de CC: carlos.lopez@suse.com Target Milestone: --- Found By: Security Response Team Blocker: --- Traefik is an open source HTTP reverse proxy and load balancer. When a request is sent to Traefik with a URL fragment, Traefik automatically URL encodes and forwards the fragment to the backend server. This violates RFC 7230 because in the origin-form the URL should only contain the absolute path and the query. When this is combined with another frontend proxy like Nginx, it can be used to bypass frontend proxy URI-based access control restrictions. This vulnerability has been addressed in versions 2.10.6 and 3.0.0-beta5. Users are advised to upgrade. There are no known workarounds for this vulnerability.
