Simply, download a pre-built binary from releases page and run!

Using cargo:

▶ cargo install ppfuzz

Manual building executable from source code:

▶ git clone https://github.com/dwisiswant0/ppfuzz
▶ cd ppfuzz && cargo build --release

ppfuzz uses chromiumoxide, which requires the Chrome or Chromium browser to be installed. If the CHROME environment variable is set, then it'll use it as the default executable. Otherwise, the filenames google-chrome-stable, chromium, chromium-browser, chrome and chrome-browser are searched for in standard places. If that fails, /Applications/Google Chrome.app/... (on MacOS) or the registry (on Windows) is consulted.

It's fairly simple to use ppfuzz!

▶ ppfuzz -l FILE [OPTIONS]

Use -l/--list to provide input list:

▶ ppfuzz -l FILE

You can also provide the list using I/O redirection:

▶ ppfuzz < FILE

— or chain it from another command output:

▶ cat FILE | ppfuzz

Only show vulnerable targets/suppress an errors:

▶ ppfuzz -l FILE 2>/dev/null

Here are all the options it supports:

▶ ppfuzz -h

• Nuclei templates
• PPScan
• Prototype Pollution and useful Script Gadgets
• JavaScript prototype pollution attack in NodeJS
• Prototype pollution – and bypassing client-side HTML sanitizers

When I started out ppfuzz, I had very little or no knowledge on Rust and I believe there may be a lot of drawbacks/security vulnerabilities. So all contributions are welcome, of course — any bug reports & suggestions are appreciated, some environment have not been tested yet.

Besides being my learning medium, this tool was created because it was inspired by a tip shared by @R0X4R on how to automate prototype pollution checking using page-fetch.

Cross-compile GitHub workflow inspired by crodjer's sysit.

Since this tool includes some contributions, I'll publically thank the following users for their helps and resources:

• @mattsse - for his awesome chromiumoxide & mentoring me which helped a lot to quickly adapt Rust!
• Fourty2#4842 (Discord) - for helpful workaround.
• All contributors.
