## Summary

The VertiGIS WebOrderSystem, specifically its OrderAdministration portal (AuftragsManager) and the related ASMobile web interface within the GIS Portal package, is affected. An attacker with a normal user account can plant malicious scripts in a business reference field that later run in the browser of a highly privileged administrator who opens the order, potentially letting the attacker act with that administrator's access.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- VertiGIS Ltd. WebOrderSystem (AuftragsManager): through 7.0.8.6

## Description

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.
