|Fixed In Version:||PKI 10.6.1||Doc Type:||If docs needed, set a value|
Dogtag PKI, through version 10.6.1, has a vulnerability in AAclAuthz.java that, under certain configurations, 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. This may result in an escalation of privileges or have other unintended consequences.

Description Sam Fowler 2018-03-15 01:28:47 UTC
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.
