Background
peiserver 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 peiserver arises from its resolution of relative file paths. By exploiting this vulnerability, an attacker can craft a request that includes '../' 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. This can result in the disclosure of sensitive information.
How To Fix
No fixed version is published for this vulnerability.
