wafw00f

wafw00f is a specialized tool designed for identifying Application Firewall (WAF) products associated with specified URLs. Within automated security workflows, it serves to enhance reconnaissance capabilities by providing insights into web application protections employed by target systems.

Ideal Use Cases & Fit​

wafw00f is optimal for scenarios where rapid identification of WAF solutions is critical, such as during web application assessments or penetration testing. It excels when fed with a list of URLs, determining the WAF in use and contributing to a comprehensive security analysis. This tool is not appropriate for environments where nuanced behavioral testing of WAFs is required, as it primarily detects indicated firewalls rather than bypassing or interacting with them in detail.

Value in Workflows​

Integrating wafw00f into security workflows streamlines the reconnaissance phase, allowing security professionals to quickly assess defenses in place. Positioned early in the workflow, it facilitates informed decision-making about subsequent testing efforts and can help prioritize targets based on WAF strength.

Input Data​

The tool requires a newline-separated list of URLs as input. This input, designated as the target function, is essential for operation. An example input file might look like:

https://example.com
https://example2.com

Configuration​

  • format: Specifies the output format, which can be set to csv, json, or text. This is a required parameter with a default value of json.
  • proxy: Indicates the use of an HTTP proxy for requests. This parameter is required and defaults to PROXY_FULL_HTTP.
  • find-all: A boolean parameter that, when set to true, enables the tool to seek out all WAFs without halting on the first discovery. This is optional and defaults to false.
  • no-redirect: Prevents following redirects from 3xx responses if enabled. This parameter is optional and defaults to false.
  • timeout: Defines the timeout duration for requests in seconds. This is an optional parameter that defaults to 30.
  • headers: Allows for the inclusion of custom headers via a designated text file. This is optional.
  • no-colors: Disables ANSI color output in the response. This parameter is required and defaults to true.
  • test: Specifies a singular WAF to test against. This is optional.
