CVE-2026-4951Reflected Cross-Site Scripting in CustomerAdministration Portal (KundenManager)in VertiGIS WebOrderSystem
Medium 5.1
In plain English
A medium-severity cross-site scripting in WebOrderSystem (KundenManager) from VertiGIS Ltd.. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 30% of all known vulnerabilities).
Official description
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.
