+-----------------------------------------------------------

Summary
=======

A vulnerability in Cisco NX-OS Software running on Cisco Nexus 3000
Series Switches and Cisco Nexus 3500 Platform Switches could allow
an unauthenticated, remote attacker to log in to the device with the
privileges of the root user with bash shell access.

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.
