CWE-78

Summary

A vulnerability in CLI command processing in the Cisco Firepower 4100
Series Next-Generation Firewall and Cisco Firepower 9300 Security Appliance
could allow an authenticated, local attacker to inject arbitrary shell
commands that are executed by the device.

The vulnerability is due to insufficient input validation of
user-controlled input parameters entered at the CLI. An attacker could
exploit this vulnerability by authenticating to the device and submitting
crafted input parameters to certain commands. A successful exploit could
