Apache Tomcat Native Connector is vulnerable to certificate validation bypass. A remote unauthenticated attacker can create a client certificate with a specially crafted AIA-Extension field that, when parsed by Tomcat Native, will trigger a parser error and cause the OCSP check to be skipped allowing the malicious user to bypass security controls on the target system.
