A fast tool to scan client-side prototype pollution vulnerability written in Rust.
Prototype pollution is a JavaScript vulnerability that enables an attacker to add arbitrary properties to global object prototypes, which may then be inherited by user-defined objects. (By PortSwigger)
Installation
Binary
Simply, download a pre-built binary from releases page and run!
Source
Using cargo
:
▶ cargo install ppfuzz
Manual building executable from source code:
▶ git clone https://github.com/dwisiswant0/ppfuzz
▶ cd ppfuzz && cargo build --release
# binary file located at target/release/ppfuzz
Dependencies
ppfuzz uses chromiumoxide, which requires 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.
Demonstration
As you can see in the demo above, ppfuzz attempts to check for prototype-pollution vulnerabilities by adding an object & pointer queries, if it’s indeed vulnerable: it’ll fingerprinting the script gadgets used and then display additional payload info that could potentially escalate its impact to XSS, bypass or cookie injection.
Usage
It’s fairly simple to use ppfuzz!
▶ ppfuzz -l FILE [OPTIONS]
Basic
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
Options
Here are all the options it supports:
▶ ppfuzz -h
Flag | Description | Default value |
---|---|---|
-l, –list | List of target URLs | |
-c, –concurrency | Set the concurrency level | 5 |
-t, –timeout | Max. time allowed for connection (s) | 30 |
-h, –help | Prints help information | |
-V, –version | Prints version information |
