Official description

A flaw was found in dogtag-pki and pki-core. The token authentication scheme can be bypassed with a LDAP injection. By passing the query string parameter sessionID=*, an attacker can authenticate with an existing session saved in the LDAP directory server, which may lead to escalation of privilege.
