    Published: 26 Sept 2019Last Modified: 24 Sept 2025

    Summary:

    Details: diag_command.php in pfSense 2.4.4-p3 allows CSRF via the txtCommand or txtRecallBuffer field, as demonstrated by executing OS commands. This occurs because csrf_callback() produces a "CSRF token expired" error and a Try Again button when a CSRF token is missing.
