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/Chrome installed:

sudo sh -c 'echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list'
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
sudo apt-get update
sudo apt-get install google-chrome-stable

Make sure to have chromedp installed:

go get -u github.com/chromedp/chromedp

Installation

• Automatically
  • Download the already compiled binary here
  • Give it the permission to execute chmod +x ppmap
• Manually (compile it yourself)
  • Clone the project:

git clone https://github.com/kleiton0x00/ppmap.git

• Change directory to ppmap folder:

cd ~/ppmapBuild the binary
go build ppmap.go

Usage

Using the program is very simple, you can either:

• scan a directory/file (or even just the website):

echo 'https://target.com/index.html' | ./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:

https://msrkp.github.io/pp/2.html
https://ctf.nikitastupin.com/pp/known.html

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 exploit & ready to perform XSS
