"According to its self-reported version, Cisco FXOS Software is affected by vulnerabilities 
in the CLI that could allow an authenticated, local attacker to execute arbitrary commands on the
underlying operating system of an affected device. This vulnerability is due to insufficient
validation of arguments passed to certain CLI commands. An attacker could exploit this vulnerability
by including malicious input as the argument of an affected command. A successful exploit could allow
the attacker to execute arbitrary commands on the underlying operating system with elevated privileges.
An attacker would need administrator credentials to exploit this vulnerability.
