Dogtag PKI through version 10.5.1 has a vulnerability in AAclAuthz.java that, under certain configuration, causes the application of ACL allow and deny rules to be reversed. If a server is configured to process allow rules before deny rules (authz.evaluateOrder=allow,deny), then allow rules will deny access and deny rules will grant access.
