CVE-2020-19203
An authenticated Cross-Site Scripting (XSS) vulnerability was found in widgets/widgets/wake_on_lan_widget.php, a component of the pfSense software WebGUI, on version 2.4.4-p2 and earlier.
Does this matter?
Lower severity and a low EPSS score (1.05%). Track it; it rarely justifies an emergency change on its own.
Description
An authenticated Cross-Site Scripting (XSS) vulnerability was found in widgets/widgets/wake_on_lan_widget.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.
