Background
larvitbase-www is an npm package that provides an API endpoint for web applications. It is used to handle HTTP requests and serve static files. The package is vulnerable to an Unintended Require vulnerability, which allows attackers to execute any .js file in the same folder as the server is running.
Vulnerability Detail
The vulnerability in larvitbase-www arises from the package exposing an API endpoint and passing an unsanitized GET parameter to a require() call. This allows attackers to inject malicious code and execute arbitrary JavaScript files on the server. The impact of this vulnerability can be severe, as it grants unauthorized access and control over the server, potentially leading to data breaches, unauthorized modifications, or even complete system compromise.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As there is no fix available, a possible workaround is to implement input validation and sanitization for the GET parameter passed to the require() call. This can help mitigate the risk of code injection. Here's an example of how to sanitize the parameter using the 'sanitize-filename' package:
const sanitizeFilename = require('sanitize-filename');
const sanitizedParam = sanitizeFilename(req.query.param);
require(sanitizedParam);
Conclusion
larvitbase-www is vulnerable to an Unintended Require vulnerability that allows attackers to execute arbitrary JavaScript files on the server. Currently, there is no fix available, so it is recommended to consider using an alternative package. Implementing input validation and sanitization can help mitigate the risk.
