Description

A vulnerability in the command-line interface of Cisco Integrated Management Controller (IMC) could allow an authenticated, local attacker with read-only credentials to inject arbitrary commands that could allow them to obtain root privileges. The vulnerability is due to insufficient validation of user-supplied input on the command-line interface.
