The vulnerability is due to a user account that has a default and static password. This account is created at installation and cannot be changed or deleted without impacting the functionality of the system. An attacker could exploit this vulnerability by connecting to the affected system using this default account. The account can be used to authenticate remotely to the device via Telnet (or SSH on a specific release) and locally on the serial console. Cisco has released software updates that address this vulnerability. Workarounds that address this vulnerability are available.
