Executive Summary

This vulnerability in ThingsBoard versions prior to v4.2.1 allows an authenticated user to upload malicious SVG images via the Image Gallery. These SVG images contain JavaScript code that executes when other users access the images through the public API endpoint or when the images are embedded in iframes on dashboards or widgets. The issue arises because the ImageController does not properly restrict JavaScript execution in loaded images, leading to Stored Cross-Site Scripting (XSS). This can result in malicious code running in other users' browser sessions.

Impact Analysis

The vulnerability can lead to the execution of malicious code in the context of other users' sessions, potentially compromising their accounts. This may allow attackers to perform unauthorized actions on behalf of other users, leading to data theft, session hijacking, or other malicious activities within the ThingsBoard platform.
