pfSense: pfSense-SA-19_07.webgui: Privilege Escalation in the WebGUI
Description
The privileges for access to the dashboard (page-dashboard-all) and for direct access to dashboard widgets (page-dashboard-widgets) contained a match clause for widget files with a leading wildcard. This allowed the URL to be manipulated in a way which could have been used to gain elevated privileges. Authenticated users with these privileges could access pages for which they had not been granted access by appending a string to the URL ending in ".widget.php", for example: https://x.x.x.x/diag_backup.php?a.widget.php Authenticated users could have used this behavior to gain elevated privileges and perform actions allowed by any page in the WebGUI.
