Background
The serverzyy package is an npm package used for server-side development. It provides various functionalities for building server applications. However, it is vulnerable to a directory traversal vulnerability that 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 serverzyy arises from the way it resolves relative file paths. By manipulating the file path in a specific manner, an attacker can traverse directories and access files outside of the intended directory root. This can result in the exposure of sensitive information, such as private files or configuration files. An example request that demonstrates this vulnerability is:
GET /../../../etc/passwd HTTP/1.1
host: foo
This vulnerability has a high severity rating and is classified under CWE-22.
