Description

In userman 13.0.76.43 through 15.0.20 in Sangoma FreePBX, XSS exists in the user management screen of the Administrator web site, i.e., the/admin/config.php?display=userman URI.

When another user (such as an admin) visits the main User Management screen, the XSS payload will render and execute in the context of the victim user's account.
