In the world of cybersecurity, knowledge is power. The more we understand about the vulnerabilities inherent in our systems, the better we can protect against malicious attacks. This blog post aims to arm you with a comprehensive checklist for web application exploitation, offering insights into the tools and techniques that can be used to exploit each vulnerability.

1. Injection Flaws:

Injection flaws, especially SQL and command injections, are extremely common web application vulnerabilities. They arise when an application sends untrusted data to an interpreter.

SQL Injection:
  • Tools: SQLmap, Burp Suite
  • Techniques: The goal is to manipulate data inputs to exploit poorly secured values that can be interpreted as SQL commands.
Command Injection:
  • Tools: Burp Suite, custom scripts
  • Techniques: These flaws occur when inputs are used in the creation of OS commands without proper sanitation.
XSS (Cross-Site Scripting):
  • Tools: Burp Suite, OWASP ZAP, XSSer
  • Techniques: Exploiting inputs to inject malicious scripts, often targeting another user.

2. Authentication and Session Management Flaws:

These vulnerabilities exploit weak password policies, predictable session tokens, and insecure account recovery methods.

  • Tools: Burp Suite, custom scripts
  • Techniques: Identifying and exploiting these vulnerabilities involves targeting weak points in the authentication and session management processes.

3. Insecure Direct Object References (IDOR):

These vulnerabilities occur when a developer exposes a reference to an internal implementation object.

  • Tools: Burp Suite, OWASP ZAP
  • Techniques: Manipulating these references to gain unauthorized access.

4. Security Misconfigurations:

Often arising from default configurations, unnecessary services, unprotected files, and directories, security misconfigurations are a rich source of vulnerabilities.

  • Tools: Nmap, Nikto, Nessus
  • Techniques: To exploit these vulnerabilities, one needs to identify and leverage these weak points in the system's security configuration.

5. Sensitive Data Exposure:

Sensitive data exposure happens when an application does not adequately protect sensitive information.

  • Tools: Wireshark, Burp Suite
  • Techniques: Intercepting traffic to extract data and exploiting weak encryption are common ways to exploit these vulnerabilities.

6. Missing Function Level Access Control:

These vulnerabilities arise when applications do not properly restrict what authenticated users are allowed to do.

  • Tools: Burp Suite, OWASP ZAP
  • Techniques: To exploit these vulnerabilities, an attacker manipulates requests to access unauthorized functions.

7. Cross-Site Request Forgery (CSRF):

A CSRF attack forces an end user to execute unwanted actions on a web application in which they're authenticated.

  • Tools: Burp Suite, OWASP ZAP
  • Techniques: The goal of a CSRF attack is to exploit the trust a web application has in its authenticated users.

8. Unvalidated Redirects and Forwards:

These vulnerabilities occur when attackers can redirect users to malicious websites or trick users into performing actions they do not intend.

  • Tools: Burp Suite, OWASP ZAP
  • Techniques: To exploit these vulnerabilities, an attacker would manipulate the redirection process to their benefit.

9. Server-side Request Forgery (SSRF):

SSRF attacks exploit the ability of a vulnerable server to make requests to other back-end resources.

  • Tools: Burp Suite, custom scripts
  • Techniques: To execute these attacks, the attacker exploits the vulnerable server's ability to create requests to intra/extranet applications.

10. XML External Entity (XXE) Injection:

XXE attacks exploit poorly configured XML parsers.

  • Tools: Burp Suite, custom scripts
  • Techniques: XXE attacks aim to disclose internal files, execute remote requests, carry out DoS attacks, and more by exploiting XML parser vulnerabilities.

In summary, understanding these vulnerabilities and knowing how to exploit them is crucial for both penetration testers and developers. Armed with this knowledge, one can ensure that applications are secure and robust, thus protecting valuable data and services from attackers.
