What is CVE-2026-20063?

A command injection vulnerability exists in the Command Line Interface (CLI) of Cisco Secure FTD Software that can be exploited by an authenticated attacker with local access. This flaw is a result of insufficient input validation for user-supplied command arguments. By providing specially crafted input for specific CLI commands, the attacker may gain the ability to execute arbitrary commands on the underlying operating system with root privileges. This presents a significant security risk, highlighting the need for strict access controls and regular security updates to mitigate potential threats.
