OWASP Penetration Testing

Technical Deep Dive—OWASP Penetration Testing

For security experts, the Open Web Application Security Project (OWASP) offers a multitude of materials including thorough penetration testing guidelines. The technical elements of OWASP penetration testing will be covered in this paper along with particular tools, approaches, and best practices for spotting and exploiting online application vulnerabilities.

OWASP Top 10: Penetration Testing

Regularly updated list of most important web application security vulnerabilities is the OWASP Top 10. It offers a strong basis for penetration testing even if it is not all-clusive. Let’s investigate every one of these weaknesses’ testing strategies:

  1. Injection.

Untrusted data given to an interpreter as part of a command or query causes injection flaws—including SQL injection.

  1. Unbroken Verification

Failures in session management and authentication may let attackers compromise passwords, keys, or session tokens.

Method of tests: Change session cookies or control request parameters to try to evade authentication.

tool: Intruder from Burp Suite

Attack a login form using Intruder using a dictionary:

Track a login request in Burp Suite.

Deliver to Intruder.

Specify payload locations for fields including login and password.

Load usernames and passwords from load words.

Begin the onslaught.

  1. Exposure to Sensitive Data

Many online apps fall short in adequately safeguarding private or financial information.

Technique of testing: Search network traffic for unencrypted sensitive data transfer.

  1. XXE XML External Entities

XML processors with poor configuration analyze external entity references within XML documents.

Method of testing: try to read sensitive files using XXE payloads.

  1. Missing Access Control

Often the limitations on what authorized users are permitted to do are not well enforced.

Testing method: Try to access resources or operate in many user capacities.

OWASP ZAP’s Active Scan tool

Set ZAP to compare access levels and use many session tokens:

Configure several ZAP users with varying rights.

Every user context should do an active scan.

Compare the findings to spot access control problems.

  1. Security Configuration Neglect

Usually coming from unsafe default settings or inadequate setups, security misconfiguration is the most typically seen problem.

Look for pointless open ports, services, and default credentials in your testing approach.

  1. Cross-site Scripting (XSS)

XSS issues arise in applications including untrusted data on a new web page without appropriate validation or escape.

Try injecting and running JavaScript in many input fields.

  1. Insecure deseralization

Attacks in remote code execution may result from insecure deseralization.

Testing method: Try to use application logic by means of serialized objects manipulation.

  1. Employing Known Vulnerability Components

Often running with full rights, components like libraries, frameworks, and other software modules may cause major data loss or server takeover if taken advantage of.

Testing method: Find and verify variations of every element used in the application.

  1. Bad Monitoring and Logging

Missing or inadequate integration with incident response combined with insufficient logging and monitoring lets attackers continue attacking systems, remain persistent, and turn to additional systems.

Try many attacks and see whether they are correctly documented and informed upon.

ELK Stack (Elasticsearch, Logstash, Kibana) can help you to consolidate logs and provide alerts for unusual activity.

Advanced OWASP Penetration Testing Methods

Beyond the Top 10, OWASP offers direction on more complex penetration testing approaches:

SSRF, or server-side request forgery

SSRF vulnerabilities arise when a web application retrieves a remote resource without verifying the user-provided URL.

Try to get the server to request internal resources.

GraphQL API Testing

GraphQL APIs are used in many contemporary online apps and need for certain testing methods.

Try to map out the API schema by use of introspection questions.

JWT Token Examination

Commonly used for authentication, JSON Web Tokens (JWTs) might be susceptible if not correctly handled.

Changing JWT claims and signatures is the testing approach.

OWASP Penetration Testing Automaton

Although hands-on testing is important, automation greatly improves penetration testing’s coverage and efficiency.

Continuous Integration/Continuous Deployment (CI/CD) Integration

Including security testing within the CI/CD flow guarantees early discovery of flaws in the development process.

Customized Scripting

Custom scripting allows one to link many tools or automate certain testing situations.

In conclusion, penetration testing for OWASP is a challenging and developing subject needing a thorough knowledge of online technology and security ideas. Using the OWASP Top 10, sophisticated testing methods, and automation technologies can let security experts do extensive and successful penetration tests.

Still, tools and methods are just one factor in the equation. A good OWASP penetration test calls also for ingenuity, tenacity, and a strong knowledge of the architecture and business logic of the target application.

Penetration testing strategies must change as web technologies develop as well. Any professional engaged in web application security testing must keep current with OWASP’s most recent materials, join the security community, and always be improving their abilities.
