ppmap

A simple scanner/exploitation tool written in GO which automatically exploits known and existing gadgets (checks for specific variables in the global context) to perform XSS via Prototype Pollution. NOTE: The program only exploits known gadgets, but does not cover code analysis or any advanced Prototype Pollution exploitation, which may include custom gadgets.

Requirements

Make sure to have Chromium installed (Chrome will also do the job):
sudo apt-get install chromium-browser

Make sure to have chromedp installed:
go get -u github.com/chromedp/chromedp

Installation

• The recommended way to install the software is to compile it yourself by executing:
  go get -u github.com/kleiton0x00/ppmap.git
  Check if it is successfuly compiled by typing in the terminal: ppmap

• If you face error during manually compiling (for some reasons), you can download the precompiled one:

  • Download the already compiled binary here
  • Give it the permission to execute chmod +x ppmap

Usage

Using the program is very simple, you can either:

• scan a directory/file (or even just the website itself):
  echo 'https://target.com' | ppmap

• or endpoint:
  echo 'http://target.com/something/?page=home' | ppmap

For mass scanning:
cat url.txt | ppmap where url.txt contains all url(s) in column.

Demo

Feel free to test the tool on the following websites as a part of demonstration and to also check if the software is working correctly:
https://msrkp.github.io/pp/2.html
https://ctf.nikitastupin.com/pp/known.html
https://grey-acoustics.surge.sh

Workflow

• Identify if the website is vulnerable to Prototype Pollution by heuristic scan
• Fingerprint the known gadgets (checks for specific variables in the global context)
• Display the final XSS payload which can be exploited
