Background
The enserver package 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 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 enserver arises from its resolution of relative file paths. By manipulating the file path in a specific way, an attacker can traverse directories and access files outside of the intended directory root. For example, an attacker can send a GET request with a crafted file path to retrieve sensitive files, such as /etc/passwd. This vulnerability poses a high risk as it can lead to the exposure of confidential information.
How To Fix
No fixed version is published for this vulnerability.
