Loading vulnerability…
ThingsBoard versions < 4.2.1 contain a server-side request forgery (SSRF) vulnerability in the dashboard's Image Upload Gallery feature. An attacker can upload a malicious SVG file that references a remote URL. If the server processes the SVG file in a way that parses external references, it may initiate unintended outbound requests. This can be used to access internal services or resources.

This repository is a small standalone Python proof-of-concept exploit for CVE-2025-34282, an authenticated SSRF issue in ThingsBoard IoT Platform before 4.2.1. The repo contains three files: a README describing the vulnerability and attack chain, a malicious SVG sample (ssrf_localhost_5555.svg), and the main exploit script (thingsboard_4.2.0_ssrf_CVE-2025-34282_exploit.py). The exploit script uses the requests library and is the sole code file. Its workflow is straightforward: first, upload a user-supplied image file to the ThingsBoard image API (/api/image) using a bearer token in the X-Authorization header; second, parse the JSON response to extract the returned publicLink; third, create a widget through /api/widgetType whose HTML template embeds that publicLink in an <object> tag. The intended effect is that ThingsBoard processes the uploaded SVG server-side and fetches the remote resource referenced in the SVG's xlink:href, thereby causing SSRF. The sample SVG targets http://127.0.0.1:5555 to demonstrate access to localhost-only services from the server. Capabilities: authenticated upload of a crafted SVG, automated extraction of the uploaded file's public link, automated widget creation to trigger rendering, and SSRF against attacker-chosen internal URLs embedded in the SVG. The exploit does not provide code execution or a shell payload; it is focused on inducing outbound HTTP requests from the vulnerable server. The script is operational but basic: target URLs are hardcoded to localhost:8080, and the attacker must already have a valid Tenant Admin token. The repository is not part of a larger exploit framework.
