Test to identify any vulnerabilities on web applications and to assess the impact of vulnerabilities by exploiting multiple attempts. The ideal time for a web application penetration test is before the site is live and exposed to potential threat but fully developed.

Webapp Pentesting Businesses rely on web applications to succeed, and cybercriminals see them as attractive targets. Web application penetration testing programs proactively look for vulnerabilities in applications, such as those that might lead to the theft of sensitive information. The purpose of web application penetration testing is to detect vulnerabilities in web applications using penetration testing techniques. It is similar to a penetration test in that it aims to break into the web application using penetration attacks. Penetration tests are used to determine if a web application is vulnerable, secure or has a security flaw or threat. The tests use any known malicious penetration attack on the application. Through the use of SQL injection tests, penetration testers exhibit/fabricate attacks and environments from an attacker's perspective. An important outcome of a web application penetration test is the identification of security weaknesses throughout the entire application and all its components (source code, database, back-end network). As well as identifying vulnerabilities and threats, it can be used for prioritizing possible mitigation measures. The scope of a penetration test for a web app is more targeted than that of vulnerability scans. The pentesting of a web app involves having an experienced tester use various tools to mimic a cyber attacker's deliberate acts or unintentional actions that could compromise the app. In order to gain access to an application's internal workings, they look for the most vulnerable entry points. Penetration testing commonly uses the following tools: · W3af · Burp Suite · SQLMap · Metasploit
· Hydra · John Ripper · Skipfish · Ratproxy · Wfuzz · Watcher An OWASP Top 10 and beyond Web Application Penetration Test covers the following classes of vulnerabilities: · Injection · Broken Authentication · Sensitive Data Exposure · XML External Entities (XXE) · Broken Access Control · Security Misconfiguration · Cross-Site Scripting (XSS) · Insecure Deserialization · Using Components with Known Vulnerabilities · Insufficient Logging & Monitoring The following vulnerabilities represent some of the top OWASP security risks to web applications.
· SQL Injection — An application's backend can be compromised by hackers altering SQL statements. These SQL injection attacks cause the application to execute commands that lead to the disclosure of information unauthorized to the user. · Cross-Site Scripting (XSS) — These malicious scripts are executed by applications executing scripts in the browser. They are used by hackers to deface websites, hijack cookie sessions, or redirect unsuspecting users to sites with sensitive information. · Broken Authentication — Cookies are usually invalidated by websites when users log out of a site or close their browser. Hackers can steal sensitive information if those cookies remain valid after expiration, and the session is left open. · Security Misconfiguration — Web developers who fail to configure a web application's security properly and its related components leave the web app vulnerable to hackers who can use APIs and input fields to access targeted areas. · Insecure Deserialization — The source code of a website can be manipulated by attackers who pass in harmful information when data under the control of a user is deserialized by a website. · XML External Entities Injection (XXE) — Attackers manipulate how web applications process XML data. They can then view files on the server and access the back-end systems that the web application relies on. · Broken Access Controls — When employees are restricted from accessing resources or performing duties outside their designated roles, an organization is at risk for an attack from within.
· Vulnerable Components — In some cases, developers use obsolete, vulnerable, or unsupported components in their websites, which give hackers an opportunity to steal sensitive information or take over companies' systems. Each of these penetration tests has advantages and disadvantages, but they all aim to accomplish the same goal. Web penetration tests can be classified as black box, white box, or grey box tests. Penetration testing can be done using different types of web penetration tests based on the needs of the client and the security professional. White box tests are comprehensive, and can be used to conduct penetration testing on the entire system of the client. Black box tests, on the other hand, take the form of an attack by an external adversary, and provide insight into how an organization's vulnerabilities and weaknesses are analyzed and exploited. Black Box Penetration testers conducting black box web penetration tests do not have any prior knowledge of the target. As part of a penetration test, the tester gathers and authenticates information about the target, assesses systems and applications, finds vulnerabilities, and attempts to exploit them. White Box Penetration testers run white box tests when they already have background knowledge about the system, organization, and vulnerability they are testing. It's much more common for penetration testers to conduct white box tests than black box tests, which target specific vulnerabilities to determine the risks they pose. Due to the fact that the tester already has details about the test subject, white box tests are not required to conduct extensive reconnaissance. Grey Box
Gray box testing combines elements of both white-box and black-box testing. In a grey box test, the penetration tester will typically know something about the target, but not to the level of detail that might be found in a white box test. As a starting point for testing, the client may provide information that a potential attacker would find useful. Despite the convenience and value that web applications offer, this convenience and value comes at a price. The data in web applications is available to anybody who is willing to do a bit of researchIncreasingly popular and evolving technologies are making web applications prone to vulnerabilities, both in design and configuration, which hackers may exploit. When it comes to penetration testing, web applications should be given priority, especially if they handle sensitive information.
