Background
The tiny-http package is an npm package used for local development and production purposes. It provides functionality for handling HTTP requests and responses. However, it is vulnerable to a directory traversal vulnerability that allows malicious actors to access files outside of the intended directory root.
Vulnerability Detail
The vulnerability in tiny-http arises from the package's resolution of relative file paths. By exploiting this vulnerability, an attacker can craft a request that includes a path traversal sequence, such as '../', to access files outside of the intended directory. This can lead to the disclosure of sensitive files on the vulnerable system. An example request demonstrating this vulnerability is:
GET /../../../etc/passwd HTTP/1.1
host: foo
This vulnerability has a high severity rating and is classified under CWE-22.
How To Fix
No fixed version is published for this vulnerability.
Unfortunately, there is no patch available for this vulnerability in tiny-http. It is recommended to only use this package for local development purposes. If the functionality provided by tiny-http is required for production, it is advised to switch to a different package that does not have this vulnerability.
