Description

A command-injection vulnerability exists in firewall_aliases_edit.php. This allows authenticated WebGUI users with privileges for firewall_aliases_edit.php to execute commands in the context of the root user. A user granted limited access to the pfSense web configurator GUI including access to firewall_aliases_edit.php via the "WebCfg - Firewall: Alias: Edit page" permission, could leverage this vulnerability to gain increased privileges, read other files, execute commands, or perform other alterations. This is not relevant for admin-level users as there are other deliberate means by which an administrator could run commands.
