XML-based SOAP Web Services are a widely used technology, which allows the users to execute remote operations and transport arbitrary data. It is currently adapted in Service Oriented Architectures, cloud interfaces, management of federated identities, eGovernment, or millitary services. The wide adoption of this technology has resulted in an emergence of numerous - mostly complex - extension specifications. Naturally, this has been followed by a rise in large number of Web Services attacks. By implementing common web applications, the developers evaluate the security of their systems by applying different penetration testing tools. However, in comparison to the well-known attacks as SQL injection or Cross Site Scripting, there exist no penetration testing tools for Web Services specific attacks. With WS-Attacker we intend to close this gap and provide developers and penetration testers automatic methods for detecting Web Services specific attacks. The tool currently supports the following attacks:

  • SOAPAction Spoofing
  • WS-Addressing Spoofing
  • Various XML Denial of Service variants
  • XML Signature Wrapping
