What it is
A vulnerability in the web-based management interface of Cisco UCS Central Software could allow an authenticated, remote attacker to achieve remote code execution or conduct information disclosure attacks on an affected device. This vulnerability is due to insufficient validation of user-supplied input in an HTTP request. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected endpoint on an affected device. A successful exploit could allow the attacker to execute arbitrary commands, write arbitrary files to the filesystem, and obtain sensitive information. To exploit this vulnerability, the attacker must have valid user credentials on the affected device. Cisco has released software updates that address this vulnerability There are no workarounds that address this vulnerability.
