This tool will check a user defined website for potentially exploitable/ vulnerable URL's by comparing them against the URL extensions in the database, for instance if your target is http://google.com and in the database you have /wp-login.php it would then check if: http://google.com/wp-login.php is available on that site by checking the response. It's a form of of scanning to help you exploit and find weaknesses within the web server. The first time you run the tool it will create a database "restuls.txt" for you, and add a few URL parameters to get you started. But you can add to or change the database as much as you wish and therefore, it's as powerful as you'd like it to be. It gives you real time feedback and the option to save all the successful results. You'll also be happy to know it's open source, and I've also included a win32 compiled version (requires .NET 3.5+). Video tutorial here http://youtu.be/yvc4q7YWpdo

OWASP URL Checker

Screen shot:

Urlscanscreen.jpeg


Introduction

An open source editable tool to scan websites for URL's which may lead to information divulging, exploits and common attack patterns.

Description

This tool will check a user defined website for potentially exploitable/ vulnerable URL's by comparing them against the URL extensions in the database, for instance if your target is http://google.com and in the database you have /wp-login.php it would then check if: http://google.com/wp-login.php is available on that site by checking the response. It's a form of of scanning to help you exploit and find weaknesses within the web server. The first time you run the tool it will create a database "restuls.txt" for you, and add a few URL parameters to get you started. But you can add to or change the database as much as you wish and therefore, it's as powerful as you'd like it to be. It gives you real time feedback and the option to save all the successful results. You'll also be happy to know it's open source, and I've also included a win32 compiled version (requires .NET 3.5+). Video tutorial here http://youtu.be/yvc4q7YWpdo
