Introduction

Web App Security Testing

Web applications play a vital role in the success of a business and are an attractive target for cybercriminals. Web Application Penetration / Security Testing (WAPT / WAST) is the process of proactively identifying applications vulnerabilities, such as those that could lead to the loss of sensitive user data, company data and financial information. This includes misconfigured SaaS web applications and server-side security controls.

Certbar undertakes Web Application Security Testing (WAST) with manual approach with our unique and well researched methodology including but not limited to OWASP Top 10, OSSTMM guidelines, SANS Top 25, etc. helping our client’s vital IT asset. We are highly focused on business logic vulnerabilities that are missed by automated scanners. Our team conducts internal discussions in a timely manner to discuss weird testing techniques which results in finding more vulnerabilities.

APPROACH

Our Approach to Dynamic Analysis

In this era of technology where the dynamic application analysis is used on a wide scale we ensure our clients stay ahead of the emerging threats. We adapt and integrate more in our methodology from the current security standards such as ASVS by OWASP, SANS top 25, MITRE | ATT & CK, NVD, OWASP top 10, NIST, and OSSTMM.

Penetration testing for web applications not only requires knowledge of the latest web application security testing tools but also a deep understanding of how to use them most effectively. To assess web app security, ethical hackers leverage a range of specialist tools. These range from specialist pen testing platforms (such as burp suite, Metasploit Pro and Kali Linux), to networking tools (such as Wireshark), and custom-developed tools and exploits written using Python, Java and PowerShell.

Process

Prerequisite & Defining Goals
  • Understand the purpose of the penetration test and goals.
  • Define the scope of the test, including specific applications and components to be tested.
  • Obtain necessary permissions and legal agreements to conduct the test.
Services Enumeration
  • Identify services and technologies used by the web application.
  • Use tools like Nmap, Nikto, and Dirb to discover open ports, services, and potential vulnerabilities.
Walkthrough Defining Application Wise Scope
  • Collaborate with stakeholders to finalize the scope for each application.
  • Detail the functionality, authentication mechanisms, and input/output data for each application.
Enhanced Information Gathering
  • Utilize tools like OSINT framework, WHOIS, Shodan, and Google Dorks to gather detailed information about the target.
  • Identify relevant domains, subdomains, IP ranges, and associated technologies.
Vulnerability Assessment
  • Apply the OWASP Top 10 and SANS Top 25 lists to identify common vulnerabilities.
  • Utilize manual and automated tools (e.g., Burp Suite, OWASP Zap) to scan for security flaws.
  • Categorize vulnerabilities based on severity (CVE, CWE) and potential impact.
Penetration Testing
  • Utilize the Penetration Testing Execution Standard (PTES) or Open Source Security Testing Methodology Manual (OSSTMM) as guidelines.
  • Employ manual testing techniques to identify vulnerabilities that automated tools might miss.
  • Conduct various attacks such as SQL injection, cross-site scripting (XSS), and others based on the application's functionality.
Post Exploitation
  • Finding Business Logic
  • Manipulating
  • Identifying maximum impact of vulnerabilities
  • If vulnerabilities are successfully exploited, delve deeper to understand potential consequences.
  • Explore the extent of compromise and gather evidence of successful exploitation.
Reporting
  • Report outlining the test methodology, findings, and associated risks.
  • Categorize vulnerabilities based on their severity using the Common Vulnerability Scoring System (CVSS) version 4.0.
  • Provide recommendations for remediation, including references to industry standards for best practices.

Technical Vulnerability Test Cases

Technical vulnerabilities can be easily found by fuzzing and our generic fuzzing list contains 400+ payloads to help our team identify those vulnerabilities. Our fuzzing list only works as an identifier. Post exploitation of that vulnerability is carried out manually. We keep on adding new and generic identifiers to our fuzzing list every quarter.

Business Logic Vulnerability Test Cases

CWE-840: Business Logic Errors: Weaknesses in this category identify some of the underlying problems that commonly allow attackers to manipulate the business logic of an application. Errors in business logic can be devastating to an entire application. They can be difficult to find automatically, since they typically involve legitimate use of the application’s functionality. However, many business logic errors can exhibit patterns that are similar to well-understood implementation and design weaknesses.
