Plution - Prototype Pollution Scanner Using Headless Chrome

Topic created · 1 Posts · 1 Views

  • Plution is a convenient way to scan at scale for pages that are vulnerable to client side prototype pollution via a URL payload. In the default configuration, it will use a hardcoded payload that can detect 11 of the cases documented here:
    What this is not
    This is not a one stop shop. Prototype pollution is a complicated beast. This tool does nothing you couldn't do manually. This is not a polished bug-free super tool. It is functional but poorly coded and to be considered alpha at best.
    How it works
    Plution appends a payload to supplied URLs, naviguates to each URL with headless chrome and runs javascript on the page to verify if a prototype was successfully polluted.
    how it is used

    • Basic scan, output only to screen:
      cat URLs.txt | plution
    • Scan with a supplied payload rather than hardcoded one:
      cat URLs.txt|plution -p '__proto__.zzzc=example'
      Note on custom payloads: The variable you are hoping to inject must be called or render to "zzzc". This is because 'window.zzzc' will be run on each page to verify pollution.
    • Output:
      Passing '-o' followed by a location will output only URLs of pages that were successfully polluted.
    • Concurrency:
    • Pass the '-c' option to specify how many concurrent jobs are run (default is 5)
      questions and answers
    • How do I install it?
      go get -u
    • why specifically limit it to checking if window.zzzc is defined?
      zzzc is a short pattern that is unlikely to already be in a prototype. If you want more freedom in regards to the javascript use instead
