Ppmap – A Scanner/Exploitation Tool Written In GO, Which Leverages Prototype Pollution To XSS By Exploiting Known Gadgets

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 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 ~/ppmap
    • Build 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
