Startup Guide is a publishing and media company that produces guidebooks and online content to help entrepreneurs navigate and connect with different startup scenes across the world. As the world of work changes, its mission is to guide, empower and inspire people to start their own business anywhere. Founded by Sissel Hansen in 2014, Startup Guide today has books in over 20 cities in Europe, the Middle East, the USA, and Asia including London, Tel Aviv, NYC and Singapore. Coming up this year are books in Asia and Africa, such as Cape Town and Tokyo! In autumn 2018, the company launched a media website, startupguide.com, which was born out of the desire to explore different types of content and reach a wider audience by taking advantage of the digital medium. At the core of Startup Guide’s three physical stores in Berlin, Copenhagen, Lisbon is the belief that there’s nothing like real-life experiences and seeing and feeling actual products. The stores double up as offices for the company’s 20-person team.

Description

ThingsBoard in versions prior to v4.2.1 allows an authenticated user to upload malicious SVG images via the "Image Gallery", leading to a Stored Cross-Site Scripting (XSS) vulnerability. The exploit can be triggered when any user accesses the public API endpoint of the malicious SVG images, or if the malicious images are embedded in an `iframe` element, during a widget creation, deployed to any page of the platform (e.g., dashboards), and accessed during normal operations. The vulnerability resides in the `ImageController`, which fails to restrict the execution of JavaScript code when an image is loaded by the user's browser. This vulnerability can lead to the execution of malicious code in the context of other users' sessions, potentially compromising their accounts and allowing unauthorized actions.
