What is URL Fuzzer?
The server's configuration makes certain that only authorized content is accessible from the outside. However, sometimes the webserver administrators or app developers have no idea what is on the server and available to the public. There are a lot of web apps that don't have adequate security measures in place to control what is or isn't available on their websites.
This inadvertently exposes critical data to the public. Fuzz testing, often known as fuzzing, is a discovery exercise that enables you to find resources that were not supposed to be publicly accessible (for example, /db.zip, /backups, /index.php.old, /archive.tgz, /source_code.zip).
Our online URL fuzzer tool will add more than 1000 the most used keywords for files and directories to the end of the URL and make a request to find an accessible URL.
To summarize, running the URL fuzzer with our tool can help you discover critical files or find hidden directories that contain sensitive information.
How to scan your web app for sensitive files or directories?
Sensitive data, such as environment variables, configuration files, passwords, database files, SSH key pairs, or even your Git repositories may be inadvertently exposed to the public. Use our tool to find them and take action on the server-side to secure and deny access to these files or directories.
How does our tool work?
To discover important files and directories, the URL fuzzer uses a custom-built wordlist. The wordlist contains more than 1,000 common names of known files and directories to run the fuzz test. An HTTP request to the target will be made with every word in the wordlist.
HTTP response codes and the page sizes are also added with accessible URLs in the report.
You can also use other open-source tools if you want:
- https://github.com/maurosoria/dirsearch
- https://github.com/nccgroup/dirble
- https://github.com/OJ/gobuster
If you find any sensitive files, you should take appropriate action to make your URLs secure.
So, to sum up, you should scan your app for sensitive URLs using a wordlist to make sure there are no publicly accessible files and directories that contain critical data. To do that, you can either use our online URL fuzzer tool or other open sources tools. If you find any such files, you should take appropriate action to secure and deny access to them.
- Apply rate limiting for consecutive requests.
- Automatically block the IP address making the request.
