Node ecstatic Internal Path Exposure Vulnerability Scanner Detail

Node ecstatic is a static file serving library for Node.js, widely used by developers to serve files over HTTP in a simple and efficient way. It is particularly popular in development environments for quick setup and in production for serving assets of Node.js applications. The library supports a range of features, including customizable file listing, automatic content type detection, and cache control. It's a key component in many web development stacks, especially when building lightweight web servers or integrating static file serving into Node.js applications. Its ease of use and efficiency make it a go-to choice for developers needing a straightforward solution for static file serving.

The vulnerability in Node ecstatic relates to internal path exposure. Due to insufficient sanitization of user input, attackers can craft specific requests that lead to the exposure of internal file paths. This vulnerability is a result of how ecstatic handles overly long URLs and errors out, inadvertently revealing internal information that should not be accessible. Such exposure could provide attackers with insights into the server's directory structure, potentially aiding in further attacks.

The internal path exposure vulnerability is triggered when ecstatic processes a request with an excessively long URL, causing an error response that includes internal file path information. Specifically, the error message 'ENAMETOOLONG', associated with the 'stat' system call, is returned in the response body along with the internal path. This occurs because the library attempts to stat the requested resource, failing with a status code of 500 when the path is too long. The inclusion of system error messages in HTTP responses without proper sanitization leads to this vulnerability, revealing internal configuration details to an attacker.

Exploitation of this vulnerability can lead to information disclosure, where an attacker gains insights into the server's internal directory structure. This knowledge can be used to craft more targeted attacks, potentially leading to unauthorized access or the discovery of unprotected files and directories. In the worst-case scenario, it could aid attackers in identifying vulnerable endpoints or files, escalating their attack surface within the target system.
