The "ASMobile" web interface, which is part of the VertiGIS software package "GIS Portal", allows authenticated users to define a business reference. JavaScript code can be inserted into this field. On its own this only affects the user who entered it (self-XSS). However, the business reference is included in the order details when the user places an order through the web interface. The order is later listed in the OrderAdministration portal (AuftragsManager) of VertiGIS WebOrderSystem, where the stored code is executed as soon as a highly privileged user opens the order. Version 7.0.8.6 of WebOrderSystem, the latest available at the time of testing, is affected. The vendor did not provide information about further affected versions.

The CustomerAdministration portal (KundenManager) of VertiGIS WebOrderSystem allows privileged users to search for employees across all defined companies (user groups). The search term can be passed in the "searchValue" URL parameter, so the search is performed when a logged-in user opens such a URL. JavaScript code placed in this parameter is executed in the victim's browser. An unauthenticated attacker who knows the URL structure can craft a link that contains script code. The code runs if a privileged user who is currently logged into the portal opens the link. Because administrative users can change the passwords of other users, including administrators, without entering the old password, an attacker may be able to take over accounts or lock out other 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.
