pfSense through 2.3.4 through 2.4.4-p3 allows Remote Code Injection via a methodCall XML document with a pfsense.execphp call containing shell metacharacters in a parameter value.

In pfSense 2.4.4-p2 and 2.4.4-p3, if it is possible to trick an authenticated administrator into clicking on a button on a phishing page, an attacker can leverage XSS to upload arbitrary executable code, via diagcommand.php and rrdfetchjson.php (timePeriod parameter), to a server. Then, the remote attacker can run any command with root privileges on that server.

An authenticated Cross-Site Scripting (XSS) vulnerability was found in widgets/widgets/wakeonlanwidget.php, a component of the pfSense software WebGUI, on version 2.4.4-p2 and earlier. The widget did not encode the descr (description) parameter of wake-on-LAN entries in its output, leading to a possible stored XSS.

A Stored Cross-Site Scripting (XSS) vulnerability was found in statusfilterreload.php, a page in the pfSense software WebGUI, on Netgate pfSense version 2.4.4-p2 and earlier. The page did not encode output from the filter reload process, and a stored XSS was possible via the descr (description) parameter on NAT rules.
