Description

Multiple Cross-Site Scripting (XSS) vulnerabilities were found in the Captive Portal area of the pfSense software WebGUI on version 2.3.2_1 and earlier. List of parameters vulnerable to reflected XSS: * status_captiveportal.php: "order", "zone" * status_captiveportal_expire.php: "zone" * status_captiveportal_test.php: "zone" * status_captiveportal_voucher_rolls.php: "zone" * status_captiveportal_vouchers.php: "zone" Due to the lack of proper encoding on the affected variables and pages succeptible to XSS, arbitrary JavaScript can be executed in the user's browser. The user's session cookie or other information from the session may be compromised.
