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.
AnalysisAI
Unauthenticated disabling of the ACME service in Dogtag PKI allows persistent denial of service via URL manipulation. By appending a trailing slash to admin-only enable/disable endpoints, an attacker can bypass the Tomcat authentication constraint while RESTEasy routes the request, enabling unauthorized toggling. No public exploit or active exploitation has been reported.
