Cisco Unified Computing System Fabric Interconnect Denial of Service Vulnerability

A vulnerability in the fabric interconnect (FI) of the Cisco Unified
Computing System could allow an authenticated, local attacker to create a denial of service (DoS) condition.

The vulnerability is due to improper
filtering of user-supplied parameters. An attacker could exploit this
vulnerability by providing certain parameters to the debug hardware
command. An exploit could allow the attacker to cause the FI to crash.

Cisco has confirmed the vulnerability in a security notice and released software updates.

To exploit this vulnerability, an attacker must be able to authenticate and have local access to a targeted device. These access requirements decrease the likelihood of a successful exploit.

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