Background
The simplehttpserver package is an npm package that provides a simple HTTP server for serving static files. It allows users to quickly set up a local server to serve files from a specified directory. However, versions prior to 0.2.1 are vulnerable to a Path Traversal vulnerability. This vulnerability arises due to insufficient input sanitization, which allows attackers to access server files by using relative paths.
Vulnerability Detail
The Path Traversal vulnerability in simplehttpserver allows attackers to bypass the intended file access restrictions and access sensitive files on the server. By manipulating the file path in the HTTP request, an attacker can traverse directories and access files outside of the intended directory. This can lead to unauthorized disclosure of sensitive information or even remote code execution if the accessed files contain executable code.
How To Fix
No fixed version is published for this vulnerability.
