Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, IOS is affected by a vulnerability in the implementation of the inter-VM channel due to insufficient validation of signaling packets that are destined to the Virtual Device Server (VDS). An unauthenticated, adjacent attacker can exploit this, by sending malicious packets to an affected device, in order to execute arbitrary shell commands on the VDS of an affected device.

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