Title
Netgate pfSense CE 2.7.1 through 2.9.0 Reflected XSS via firewall_rules.php
Summary
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.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
