wafw00f - Web Application Firewall Fingerprinting Toolkit

2.4.2 verified Fri May 01 auth: no python

wafw00f (v2.4.2) identifies and fingerprints Web Application Firewall (WAF) products protecting a website. It sends a set of HTTP requests and analyzes responses to detect over 200 WAFs. The library is actively maintained with regular releases, typically several per year.

pip install wafw00f

Common errors

error ModuleNotFoundError: No module named 'wafw00f' ↓

cause The library is not installed or installed in a different environment.

fix

Run 'pip install wafw00f' in your active environment.

error AttributeError: module 'wafw00f' has no attribute 'WafW00F' ↓

cause Attempting to use a wrong import or referring to the class incorrectly.

fix

Use 'from wafw00f import WafW00F' and then instantiate with 'WafW00F(url)'.

error TimeoutError: The read operation timed out ↓

cause Target server is slow and the default timeout may not be respected in older versions.

fix

Upgrade to wafw00f >=2.4.1 and/or pass a timeout parameter: WafW00F(url, timeout=10).

Warnings

deprecated The use of setup.py is deprecated; installation via pip works without it. ↓

fix Use pip install wafw00f instead of any manual setup.py invocations.

gotcha The main function is named identwaf (not identify_waf). The W in WafW00F is uppercase. ↓

fix Use waf.identwaf() correctly.

gotcha The WafW00F constructor can hang indefinitely on slow-streaming servers if timeout is not set explicitly. ↓

fix Upgrade to >=2.4.1 where timeout enforcement is fixed.

breaking Python 2 support removed; Python >=3.10 required. ↓

fix Use Python 3.10 or newer.
