This tool will help you identify whether a store is leaking information through it’s cache. It was originally developed in the MagX project a while ago and now distributed for learning and security purposes.
There are not many stores suffering this issue, mostly older or poorly maintained stores. Nonetheless it’s the most accurate i know, therefore worth sharing.
Usage
There is one command, called check. It accepts several parameters but also runs interactive.
./cacheleak.phar check [url]
