A vulnerability in the Cisco Management Controller of the Cisco Unified Computing System could allow an authenticated, local attacker to execute commands on the underlying operation system with elevated privileges. The vulnerability is due to improper parameter input validation. An attacker could exploit this vulnerability by providing invalid parameters to the MCTools application from the CLI of a Fabric Interconnect device. A successful exploit could allow the attacker to inject arbitrary commands to the underlying operating system with elevated privileges. 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 the targeted device. These access requirements limits 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.
The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
