OWASP Attack Surface Detector Project
During web application penetration testing, it is important to enumerate your application's attack surface. While Dynamic Application Security Testing (DAST) tools (such as Burp Suite and ZAP) are good at spidering to identify application attack surfaces, they will often fail to identify unlinked endpoints and optional parameters. These endpoints and parameters not found often go untested, which can leave your application open to an attacker.
What is the Attack Surface Detector?
Attack Surface Detector ZAP and Burp Plugins
This tool is the Attack Surface Detector, a plugin for OWASP ZAP and PortSwigger Burp Suite. This tool figures out the endpoints of a web application, the parameters these endpoints accept, and the data type of those parameters. This includes the unlinked endpoints a spider won't find in client-side code, or optional parameters totally unused in client-side code. The plugin then imports this data into ZAP or Burp so you view the results, or work with the detected endpoints and parameters from the target site map.
Attack Surface Detector Command Line Interface
The attack-surface-detector-cli program is a command-line tool that takes in a folder location and outputs the set of endpoints detected within that codebase. It uses the ASTAM Correlator's threadfix-ham module to generate these endpoints. The endpoints are output to the console by default, and can save a JSON version of those endpoints through the -output-file and -json flags. This JSON output can then be imported by the OWASP ZAP and Burp plugins allowing the user to use the built in functionality of these proxy tools.
How it Works
The Attack Surface Detector Implements the HAM engine to perform static code analyses to identify web app endpoints by parsing routes and identifying parameters (with supported languages and frameworks). This data is made available in Burp Suite and OWASP ZAP
The Attack Surface Detector plugin is free to use. It is licensed under the link Mozilla Public License 2.0.
Contributions to the Attack Surface Detector project are encouraged and welcome. Additions of new features and enhancements can be provided through GitHub. We encourage users to assess the technology through individual evaluations, pilots and/or case studies.
