## Affected

- Cisco Cisco Firepower Extensible Operating System (FXOS): version range not reported

## Description

Multiple vulnerabilities in the CLI of Cisco FXOS Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to execute commands on the underlying operating system (OS) with root privileges. These vulnerabilities are due to insufficient input validation. An attacker could exploit these vulnerabilities by including crafted arguments to specific CLI commands. A successful exploit could allow the attacker to execute commands on the underlying OS with root privileges.
