Background
serverxxx is an npm package used for local development. It provides functionality for resolving file paths. However, it is vulnerable to a directory traversal attack, where a malicious actor can 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 serverxxx arises from its resolution of relative file paths. By manipulating the file path in a specific way, an attacker can traverse directories and access files outside of the intended root. For example, an attacker can send a GET request with a crafted file path to retrieve sensitive files, such as /etc/passwd. This vulnerability poses a high risk as it can result in the unauthorized disclosure of private information.
