Description
A vulnerability in the CLI of Cisco UCS Manager Software could allow an authenticated, local attacker with administrative privileges to read or create a file or overwrite any file on the file system of the underlying operating system of an affected device, including system files. This vulnerability is due to insufficient input validation of command arguments supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected command. A successful exploit could allow the attacker to read or create a file or overwrite any file on the file system of the underlying operating system of the affected device, including system files. To exploit this vulnerability, the attacker must have valid administrative credentials on the affected device.
