Description
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.

Executive Summary

CVE-2025-34282 is a server-side request forgery (SSRF) vulnerability in ThingsBoard versions prior to 4.2.1, specifically in the dashboard's Image Upload Gallery feature. An attacker can upload a malicious SVG file that contains references to remote URLs. When the server processes this SVG file and parses its external references, it may unintentionally make outbound requests to those remote URLs. This can be exploited to access internal services or resources that are normally inaccessible. [1]

Impact Analysis

This vulnerability can allow an attacker to make the server initiate unintended outbound requests to remote URLs referenced in a malicious SVG file. This can lead to unauthorized access to internal services or resources behind the server's network, potentially exposing sensitive information or enabling further attacks within the internal network. The impact affects confidentiality, integrity, and availability at low to limited levels. [1]

Detection Guidance

This vulnerability can be detected by monitoring for uploads of SVG files containing external URL references in the ThingsBoard dashboard's Image Upload Gallery feature. Network monitoring tools can be used to detect unexpected outbound requests initiated by the server to remote URLs referenced in SVG files. Specific commands are not provided in the resources, but inspecting uploaded SVG files for external references and monitoring outbound HTTP requests from the server to unusual destinations can help detect exploitation attempts. [1]

Mitigation Strategies

Immediate mitigation steps include upgrading ThingsBoard to version 4.2.1 or later, where the vulnerability is fixed by adding a Content-Security-Policy (CSP) header to the /public image API endpoint to prevent execution of malicious scripts in SVG files. Additionally, restricting or validating SVG uploads to disallow external references can help mitigate the risk. Applying the official patch or update is the recommended action. [2, 3]
