"According to its self-reported version, Cisco Identity Services Engine is affected by a XML external element (XXE)
vulnerability. A remote attacker, authenticated with Super Admin or Proxy Admin credentials can exploit this
vulnerability by uploading a crafted XML file that contains references to external entities. A successful exploit can
allow the attacker to retrieve files from the local system resulting in a disclosure of confidential information. The
attacker can also cause the web application to perform arbitrary HTTP requests and conduct a server-side request
forgery attack through the affected device or impact the responsiveness of the web-based management interface.

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