Background
The wffserve package is an npm package used for local development. It provides functionality for serving files over HTTP. 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 wffserve arises from the package resolving relative file paths without proper validation. By exploiting this vulnerability, a malicious actor can craft a request that includes directory traversal sequences to access files outside of the intended directory root. For example, an attacker can send a GET request with a crafted path like GET /../../../etc/passwd to retrieve the /etc/passwd file. This can result in the exposure of sensitive information.
How To Fix
No fixed version is published for this vulnerability.
