Background
dcserver is an npm package used for local development. It provides functionality for resolving relative 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 dcserver arises from its improper resolution of relative file paths. By exploiting this vulnerability, an attacker can craft requests that traverse directories and access files outside of the intended directory root. For example, an attacker can send a GET request to access the /etc/passwd file on the system. This can result in the disclosure of sensitive information.
How To Fix
No fixed version is published for this vulnerability.
