Fixed In Version: tomcat-native 1.2.17
Doc Type: If docs needed, set a value
Doc Text:
When using pre-produced responses from an OCSP responder, Tomcat Native did not correctly validate the status of certificates. This allowed for revoked client certificates to be incorrectly identified. It was therefore possible for users to authenticate with revoked certificates when using mutual TLS.

Description Sam Fowler 2018-05-23 06:16:44 UTC 
Apache Tomcat Native has a flaw that does not properly check OCSP pre-produced responses, which are lists (multiple entries) of certificate statuses. Subsequently, revoked client certificates may not be properly identified, allowing for users to authenticate with revoked certicates to connections that require mutual TLS.
