Stored XSS via unencoded interface group members

Published Oct 22, 2024 · Updated Oct 22, 2024

Stored XSS in Netgate pfSense 2.5.2 allows remote authenticated users to execute scripts in an administrator's browser. Interface group members submitted through interfaces_groups_edit.php are stored without validation and rendered by interfaces_groups.php without HTML encoding. The attacker needs interface-group edit privileges, and exploitation occurs when an administrator views the group list, enabling actions within that browser session.
