Netgate pfSense CE 2.7.1 through 2.9.0 contains a reflected cross-site scripting vulnerability in firewall_rules.php that allows remote attackers to inject script via the unencoded if parameter. When the non-default Require Firewall Interface option is enabled, attackers can lure users with firewall rules privileges into opening a crafted GET link to execute script in the WebGUI with their privileges.
