ThingsBoard vulnerabilities

ThingsBoard v4.3.0.1 is vulnerable to an authentication bypass during the OAuth authorization code exchange. The application improperly trusts user-supplied identity data within the user parameter of the /login/oauth2/code/ endpoint.

An SSRF vulnerability in the Image Upload Gallery feature of ThingsBoard versions prior to 4.2.1 allows an attacker to upload a malicious SVG file referencing a remote URL. Server processing may trigger unintended outbound requests.

ThingsBoard contains a prototype pollution vulnerability which may lead to arbitrary code execution within a sandboxed context by a user who can log in to the affected product with the tenant administrator privilege (TENANT_ADMIN).

In ThingsBoard up to version 4.3.1.1, a vulnerability in the getGatewayDockerComposeFile function of /api/v1/provision (YAML Handler component) allows code injection. Remote attack is possible but difficult.

ThingsBoard versions prior to v4.2.1 allow an authenticated user to upload malicious SVG images via the Image Gallery, leading to stored XSS. The exploit can be triggered when any user accesses the public API endpoint or embeds the image in an iframe during widget creation. The vulnerability resides in ImageController, which fails to restrict JavaScript execution.

An issue in ThingsBoard 3.4.1 allows low-privileged attackers (CUSTOMER_USER) to escalate privileges to administrator level (TENANT_ADMIN or SYS_ADMIN). The attack requires knowledge of the corresponding API parameter (authority: value).
