## Overview

The CustomerAdministration portal (KundenManager) of VertiGIS WebOrderSystem allows privileged users to manage the employees of defined companies (user groups). User properties, for example the "secondName" parameter, can be filled with JavaScript code while editing a user. The code is stored and executed in the browser of any other privileged user who opens the edited user entry or the user overview of the corresponding user group. An authenticated attacker with access to the portal can use this to run script code in the session of other portal users. Version 7.0.8.6, the latest available at the time of testing, is affected. The vendor did not provide information about further affected versions.
