Technical details
This is a reflected XSS vulnerability in the KundenManager component triggered via the "searchValue" URL parameter. The vulnerability requires the victim to be an authenticated privileged user who visits an attacker-crafted URL; no user interaction beyond clicking the link is needed. An unauthenticated attacker can inject arbitrary JavaScript that executes in the victim's authenticated session, potentially enabling account takeover or privilege escalation attacks, especially since the application allows password resets without verification of the old password.
Affected products
- VertiGIS WebOrderSystem <=7.0.8.6
