A vulnerability in the fabric interconnect of the Cisco Unified Computing System could allow an authenticated, local attacker to execute commands on the underlying operating system.
The vulnerability is due to improper filtering of user-supplied parameters. An attacker could exploit this vulnerability by providing parameters to some file-related commands. An exploit could allow the attacker to execute arbitrary commands on the underlying operating system or obtain a command shell 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 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.
