Bad_url_scan NPM

Bad url scan

A simple bad URL scanner for JavaScript

This firewall has over 50 bad URLs that are commonly used in attacks.

Installation

npm install bad_url_scan

Usage

const scan = require("bad_url_scan");

scan("https://example.com/admin"); // Returns true

scan("https://example.com/blogs/my_trip.html"); // Returns false

Example usage

Here is an example of a web server that uses this package to scan URLs:

app.get('/', (req, res) => {
    const url = req.query.url;
    const bad = scan(url); // Returns true if the URL is bad
    if (bad) {
        res.send("Forbidden");
    } else {
        res.send("Hello World")
    }
});

If you want to allow a URL that is classed as bad, you can make a ignore list to ignore certain URLs:

scan("https://example.com/results/database", ["results/database"]); // Returns false

scan("https://example.com/admin", ["results/database"]); // Returns true
