AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Rendertron 1.0.0 allows remote attackers to read arbitrary files via a 'file://' URL, leading to Local File Inclusion.

Vulnerability

Rendertron 1.0.0, a headless Chrome rendering solution, does not properly validate the protocol of requested URLs. The official description notes that alternative protocols such as file:// are allowed, introducing a Local File Inclusion (LFI) vulnerability [1][3]. Affected versions include 1.0.0 and possibly earlier releases; the project has been deprecated and is no longer maintained [1].

Exploitation

A remote attacker with network access to the Rendertron HTTP server can send a request with a file:// URL (e.g., file:///etc/passwd). The server will render and serialise the local file content, returning it in the response. No authentication or special privileges are required beyond reachability of the service [1][3].

Impact

Successful exploitation allows an unauthenticated remote attacker to read arbitrary files on the server's filesystem, leading to information disclosure of sensitive data such as configuration files, credentials, or source code. The attacker gains the file contents as they would appear rendered by Headless Chrome, limited to text-based or parsable files [1][3].

Mitigation

Rendertron is deprecated and no longer actively maintained; no official patch has been released for this specific vulnerability [1]. Users should migrate away from Rendertron and adopt alternative rendering approaches, as the project itself recommends. A pull request (#88) was created to address the issue by adding input validation, but it was not merged into a release [4]. If continued use is unavoidable, restrict network access to the Rendertron instance and avoid exposing it to untrusted clients.
