Background
The simple-npm-registry package is an npm package used for local development. It provides functionality for managing a simple npm registry. However, it is vulnerable to a directory traversal attack, which allows an attacker to access files outside of the intended directory root. This can lead to the disclosure of private files on the vulnerable system.
Vulnerability Detail
The vulnerability in simple-npm-registry arises from its resolution of relative file paths. By exploiting this vulnerability, a malicious actor can craft a request that includes a path traversal sequence, such as '../', to access files outside of the intended directory root. For example, an attacker could send a GET request to access the '/etc/passwd' file on the system. This can result in the exposure of sensitive information, such as user credentials or other private files.
