Version Summary:Cisco Unified Computing System Director contains a vulnerability that could allow an unauthenticated, remote attacker to take complete control of the affected device. Updates are available.
 
 
Description
A vulnerability in Cisco Unified Computing System (UCS) Director could allow an unauthenticated, remote attacker to take complete control of the affected device.

The vulnerability is due to a default root user account created during installation. An attacker could exploit this vulnerability by accessing the server command-line interface (CLI) remotely using the default account credentials. An exploit could allow the attacker to log in with the default credentials, which provide full administrative rights to the system.

Cisco has confirmed the vulnerability in a security advisory and has released software updates.
 
Warning Indicators
Cisco UCS Director versions prior to 4.0.0.3 are affected.
 
IntelliShield Analysis
To exploit this vulnerability, an attacker may need access to trusted, internal networks and the location of targeted device, which may require footprinting the network. An attacker who locates the targeted device could attempt to log in the device with the default credentials from the CLI, which could be access via SSH.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
