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.

AI Analysis

Impact

The vulnerability is a reflected cross‑site scripting flaw in the CustomerAdministration portal of VertiGIS WebOrderSystem. JavaScript supplied in the searchValue URL parameter is executed in the victim's browser when a privileged user opens the link. This allows an attacker to run arbitrary client‑side code in the context of an authenticated administrator, potentially enabling actions such as resetting or locking other users' passwords.

Affected Systems

Affected product is VertiGIS WebOrderSystem (KundenManager) version 7.0.8.6, the latest version tested. The vendor has not disclosed additional affected releases, so all versions from 7.0.8.6 onward should be inspected.

Risk and Exploitability

The vulnerability receives a CVSS score of 5.1, indicating moderate severity. It is not listed in the CISA KEV catalog. The attack requires an attacker to know the URL structure and a privileged user to click the crafted link; social engineering is a likely launch vector. Because the vendor has not released a patch, the risk persists until vendor mitigation is obtained or a workaround is applied.
