"According to its self-reported version, Cisco NX-OS Software is affected by a vulnerability.

  - A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to execute
    arbitrary commands as root on the underlying operating system of an affected device. This vulnerability is
    due to insufficient validation of arguments that are passed to specific configuration CLI commands. An
    attacker could exploit this vulnerability by including crafted input as the argument of an affected
    configuration CLI command. A successful exploit could allow the attacker to execute arbitrary commands on
    the underlying operating system with the privileges of root. Note: To successfully exploit this
    vulnerability on a Cisco NX-OS device, an attacker must have Administrator credentials. (CVE-2024-20399)
