Execution Flow

Explore

  1. Spider: Using an automated tool, an attacker follows all public links on a web site. They record all the links they find.

    2. Techniques
    Use a spidering tool to follow and record all links.
    Use a proxy tool to record all links visited during a manual traversal of the web application.

Experiment

  1. Attempt well-known or guessable resource locations: Using an automated tool, an attacker requests a variety of well-known URLs that correspond to administrative, debugging, or other useful internal actions. They record all the positive responses from the server.

    2. Techniques
    Use a spidering tool to follow and record attempts on well-known URLs.
    Use a proxy tool to record all links visited during a manual traversal of attempts on well-known URLs.

Exploit

  1. Use unauthorized resources: By visiting the unprotected resource, the attacker makes use of unauthorized functionality.

    2. Techniques
    Access unprotected functions and execute them.

  2. View unauthorized data: The attacker discovers and views unprotected sensitive data.

    3. Techniques
    Direct request of protected pages that directly access database back-ends. (e.g., list.jsp, accounts.jsp, status.jsp, etc.)
