CVE-2026-4952
MediumCVSS 5.1Summary
The ASMobile web interface in the VertiGIS GIS Portal package allows authenticated users to define a business reference into which JavaScript code can be inserted. On its own this is self-XSS, but the business reference is included in order details and later displayed in the OrderAdministration portal (AuftragsManager) of VertiGIS WebOrderSystem, where the code executes when a highly privileged user opens the order.
Risk Assessment
A privileged user opening the order may become the victim of an XSS attack, potentially leading to session hijacking or unauthorized actions in their context. This may compromise the security of the ordering system.
Recommendation
Update WebOrderSystem to a patched version when available and implement input validation/sanitization for the business reference field. Consider restricting users' ability to enter JavaScript code.
Other vulnerabilities in VertiGIS WebOrderSystem
See all- CVE-2026-4951Medium
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, and JavaScript code in this parameter executes in the victim's browser.
- CVE-2026-4950Medium
The CustomerAdministration portal (KundenManager) of VertiGIS WebOrderSystem allows privileged users to manage employees of defined companies (user groups). User properties such as 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.
Original NVD description (English source)
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.
