CVE-2019-3864Network attack vector

Account access via reusable leaked CSRF token

Published Jan 21, 2020 · Updated Aug 4, 2024

Cross-site request forgery in Red Hat Quay 2.x before 3.0.0 allows remote attackers to access the service as a user via a leaked token. The web GUI places its _csrf_token in POST parameters, exposes it in some query strings, and reuses it across logout and subsequent login sessions. Exploitation requires obtaining a user's leaked token and inducing user interaction; successful use inherits that account's access.
