8.8 highEPSS 55%

High (8.8) in netgate pfsense. EPSS 55% chance of exploitation in the next 30 days.

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.
