Dogtag-pki: pki-core: redhat-pki: pki: acme admin enable/disable endpoint authentication bypass via trailing slash PUBLISHED

Description (CNA)

A flaw was found in Dogtag PKI's ACME responder where the web.xml security constraints use exact URL pattern matching for admin-only enable/disable endpoints. By appending a trailing slash to the URL, an unauthenticated attacker can bypass the Tomcat authentication constraint while RESTEasy still routes the request to the handler, allowing unauthorized toggling of the ACME service state including persistent denial of service.
