Cisco Unified Computing System up to 1.4 Access Restriction input validation

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Cisco Unified Computing System up to 1.4 (Virtualization Software). It has been classified as critical. Affected is an unknown code block of the component Access Restriction. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on integrity, and availability. CVE summarizes:

The Integrated Management Controller (IMC) in Cisco Unified Computing System (UCS) 1.4(7h) and earlier on C-Series servers allows remote attackers to bypass intended access restrictions by sending crafted DHCP response packets on the local network, aka Bug ID CSCuf52876.
