The vulnerability is due to an insufficient authentication mechanism used to establish a VNC session. An attacker could exploit this vulnerability by intercepting an administrator VNC session request prior to login. A successful exploit could allow the attacker to watch the administrator console session or interact with it, allowing admin access to the affected device. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
