Dogtag-pki: pki-core: redhat-pki: pki: acme admin enable/disable endpoint authentication bypass via trailing slash
Summary
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. Affected products named by the advisory: Red Hat Certificate System 10; Red Hat Certificate System 11; Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 7; and 2 more. Affected products named by the advisory: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9.
What this means
In plain English
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. Affected products named by the advisory: Red Hat Certificate System 10; Red Hat Certificate System 11; Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 7; and 2 more. The official description indicates that exploitation does not require prior authentication. An authentication bypass can allow protected functionality to be reached without completing the intended identity checks.
