CookieCatcher – Tool to assist in the exploitation of XSS

CookieCatcher is an open source application which was created to assist in the exploitation of XSS (Cross Site Scripting) vulnerabilities within web applications to steal user session IDs (aka Session Hijacking). The use of this application is purely educational and should not be used without proper permission from the target application.

Download the source from github git clone or use the ZIP file and extract it on your server.

Setup the directory as a virtualhost in Apache (I won’t go over these details, however, you may ask me via email or you can use google.)

Create a database for the application and load the SETUP.sql file.

Setup a cron job as shown in the SETUP.cron file.

A live demo of the application can be viewed at Small domain names are recommended to cut down on the character space needed for the payloads.
