CVE-2010-20059Public exploitNetwork attack vector

Unauthenticated root command execution via cmd parameter

Published Aug 20, 2025 · Updated May 15, 2026

OS command injection in iXsystems FreeNAS before 0.7.2 rev 5543 allows remote attackers to execute commands as root via the web interface. Unauthenticated access to exec_raw.php passes the cmd parameter directly to the underlying shell without sanitization. A crafted HTTP request is sufficient; successful exploitation grants administrative command execution and can read, alter, or delete appliance data.
