Background
liuyaserver is an npm package used for local development. It provides functionality for resolving file paths. However, it is vulnerable to a directory traversal attack, which allows malicious actors 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 liuyaserver arises from its improper resolution 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 retrieve the '/etc/passwd' file by including multiple '../' sequences in the request path. This can result in the disclosure of sensitive information stored in files on the system.
How To Fix
No fixed version is published for this vulnerability.
