 escalation vulnerability due to an insufficient role-based access control. An authenticated, remote attacker can 
 exploit this, by sending a specially crafted request, to gain administrative access with write privileges on the 
 system.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.
