One of the main issues people face in web application based organizations is the channel of communication between the security team and developers. This often involves lengthy steps for reproduction of vulnerabilities. Often times these are tedious to follow let alone repeat multiple times for the pentesters. So, I was behind a solution to this problem. Mozilla ZEST is something that I have known for a while. ZEST allows to replay requests and some assert statements. The serious limitation of this approach is in modern day web applications which need complex user interactions on the interface.

Solution

To encounter the above limitation I assumed the logical way is to use a browser extension to record/replay user interactions like clicks and input fills. The stringent rules on web extensions in chrome don't allow you to read/tamper requests. Hence, the hybrid solution is to use a proxy and write an extension that makes use of that proxy to tamper & record required requests.

Pocuito

Pocuito is a two part solution.

  • Extension that you install on your browser.
  • Proxy server which can be deployed for multiple users inside your org network.

NOTE: The proxy maintains session based on the remote_ip it sees the request from, hence use it from local network

Download

You can download the extension & proxy on Github Releases.

Usage

I highly suggest going through the README which will stay updated all the time.
