## Overview

A stored Cross-Site Scripting (XSS) vulnerability in the profile management functionality of T-Systems’ TAO 2.0 suite. An authenticated user could inject malicious HTML or JavaScript content into the fields containing their personal data. The content entered is stored and displayed without being properly sanitised when another user, including administrative staff, views the affected profile. Successful exploitation could allow JavaScript code to be executed in the victim’s browser, access to information available within the session, or the performance of actions using the victim’s permissions.

## Remediation
