An unauthenticated, remote attacker could exploit this by sending a crafted HTTP request to the web-based management to execute arbitrary code as the root user on an affected device.

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
