The web application penetration testing process is carried out to identify and report the existing vulnerabilities in a web application. It can be performed by analyzing and reporting the existing issues in the application, including input validation, code execution, SQL injection, and CSRF.
The best QA company has one of the most effective ways to test and secure web applications through a serious process. This involves conducting multiple tests on different types of vulnerabilities.
Web Application penetration testing is a vital element of any digital project to ensure that the quality of the work is maintained.
Gathering of Information
Through this phase, you collect information about your targets by using publicly available sources. These include websites, databases, and apps connected to the ports and services you are testing. After collecting all of this data, you will have a comprehensive list of your targets, including the names of all of our employees and their physical locations.
Important Things to Note
Use the tool known as GNU Wget; this tool aims to recover and interpret the robot.txt files.
The software should be checked for the latest version. Various technical components can be affected by this issue, such as the database details.
Other techniques include zone transfers and reverse DNS queries. You can also use web-based searches to resolve and find DNS queries.
The goal of this process is to identify the entry point of an application. This can be accomplished through using of various tools such as WebscarabTemper Data, OWSAP ZAP, and Burp Proxy.
Use tools such as Nessus and NMAP to perform a variety of tasks, including searching and scanning for vulnerabilities in the directories.
Using a conventional Fingerprint Tool, such as Amap, Nmap, or TCP/ICMP, you can perform various tasks related to the authentication of an application. These include checking for extensions and directories that are recognized by the application's browser.
Authorization Testing
For instance, test if cookies and parameters are set correctly in web spider tools. Also, check if unauthorized access to reserved resources is allowed.
The goal of this process is to test the role and privilege manipulation in order to access the resources of a web application . Analyzing the input validation functions in the web app will allow you to perform path traverses.
Authentication Testing
If the application logs out after a certain period of time, it is possible that the session will be reused. Also, it is possible that the application will automatically remove the user from the idle state.
Social engineering techniques can be used to try and reset a password by cracking the code of a login page. If the "Remember my password" mechanism is implemented, this method will allow you to easily remember your password.
If the hardware devices are connected to an external communication channel, they can communicate independently with the authentication infrastructure. Also, test if the security questions and answers presented are correct.
A successful SQL injection can cause a customer's trust to be lost. Also, it can lead to the theft of sensitive data such as credit card details. To prevent this, a web application firewall should be placed on a secure network.
Validation Data Testing
JavaScript code analysis is performed by performing various tests to identify errors in the source code. These include blind SQL injection testing and Union Query testing. You can also use tools such as sqldumper, power injector, and sqlninja to perform these tests.
Use tools such as Back frame, ZAP, and XSS Assistant to analyze and test for stored XSS. Also, perform testing for sensitive information using a variety of methods.
Administer the Backend Mail server using an injection technique. Test the XPath and SMTP injection techniques to access the confidential information stored in the server. Also, perform code injection testing to identify errors in the input validation.
Test various aspects of the application control flow and stack memory information using buffer overflow. For instance, splitting cookies and smuggling web traffic.
Management Configuration Testing
Check the documentation for your application and server. Also, make sure that the infrastructure and admin interfaces are working properly. Make sure that the old versions of the documentation are still present, and they should include the source codes, passwords, and installation paths of your software.
Check the options for implementing HTTP methods using Netcat and Telnet. Also, test the credentials of the users for those who are authorized to use these methods. To review the source code and the log files, perform a configuration management test.
Çözüm
Artificial intelligence (AI) is expected to play a vital role in improving the efficiency and accuracy of penetration testing by allowing pen testers to perform more effective assessments. However, it is still essential to note that they still need to rely on their knowledge and experience to make informed decisions.
