Background
The caolilinode package 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, which allows a malicious actor 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 caolilinode arises from its improper handling of relative file paths. By exploiting this vulnerability, an attacker can craft a request that includes multiple '../' sequences to 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 by including multiple '../' sequences in the request path. This can result in the disclosure of sensitive information.
How To Fix
No fixed version is published for this vulnerability.
