Key facts

Description

Lorensbergs Connect2 3.13.7647.20190 is affected by an XSS vulnerability. Exploitation requires administrator privileges and is performed through the Wizard editor of the application. The attack requires an administrator to go into the Wizard editor and enter an XSS payload within the Page title, Page Instructions, Text before, Text after, or Text on side box. Once this has been done, the administrator must click save and finally wait until any user of the application performs a booking for rental items in the booking area of the application, where the XSS triggers.

There is no effective way for the product to defend users in the face of a malicious administrator
