CVE-2025-20238

Root command execution via insufficient command validation

Published Aug 14, 2025 · Updated Feb 26, 2026

Command injection in Cisco Secure Firewall ASA and FTD Software allows local users to execute operating-system commands as root. The command-processing path fails to validate crafted input supplied to specific commands before passing it to the underlying operating system. Valid administrative credentials and local access are required, and successful exploitation grants root-level command execution without reported availability impact.
