Description

A vulnerability in the Cisco Integrated Management Controller (IMC) of Cisco Unified Computing System (UCS) C-Series Servers could allow an unauthenticated, adjacent attacker to access specific controls on the Cisco IMC on an affected device.

The vulnerability is due to insufficient input validation for DHCP response packets. An attacker could exploit this vulnerability by sending crafted DHCP packets to the device.

Cisco has confirmed the vulnerability in a security notice; however, software updates are not available.

To exploit this vulnerability, an attacker must be on the same broadcast or collision domain as the targeted device to send crafted DHCP packets to the device. This access requirement decreases the likelihood of a successful exploit.
