Background
Dasafio 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 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 dasafio arises from its improper handling of file paths. By manipulating the file path in a specific way, an attacker can traverse directories and access files outside of the intended scope. For example, an attacker can send a GET request with a crafted file path to retrieve sensitive files like '/etc/passwd'. This vulnerability poses a moderate risk as it can result in the exposure of confidential information.
