Description of the vulnerability

The OpenSAML Java product uses the MetadataPKIX trust engine.

However, MetadataPKIX accepts an X.509 credential when there is no Trusted Name available for an entityID. This case occurs when an entity has a RoleDescriptor KeyDescriptor containing no KeyName element. Editor's announce indicates the list of vulnerable configurations.

An attacker with a certificate provided by one of the Trust Anchors indicated in shibmd:KeyAuthority can therefore impersonate the identity of an entity, in order to escalate his privileges on an application using OpenSAML Java.
