HTTP Parameter Pollution (HPP) is a web application vulnerability exploited by injecting encoded query string delimiters in already existing parameters. The vulnerability occurs if user input is not correctly encoded for output by a web application. [1] This vulnerability allows the injection of parameters into web application-created URLs.
w3af (Web Application Attack and Audit Framework) is an open-source web application security scanner. The project provides a vulnerability scanner and exploitation tool for Web applications. [ 2 ] It provides information about security vulnerabilities for use in penetration testing engagements.
While this vulnerability is similar to cross-site scripting, template injection can be leveraged to execute code on the web server rather than in a visitor's browser. It abuses a common workflow of web applications, which often use user inputs and templates to render a web page. The example below shows the concept.
The rise of web applications entailed testing them: Verizon Data Breach reports in 2016 that 40% of all data breaches use web application vulnerabilities. [14] As well as external security validations, there is a rise in focus on internal threats.
The Open Worldwide Application Security Project (formerly Open Web Application Security Project [7]) (OWASP) is an online community that produces freely available articles, methodologies, documentation, tools, and technologies in the fields of IoT, system software and web application security.
Common Weakness Enumeration (CWE) logo. The Common Weakness Enumeration (CWE) is a category system for hardware and software weaknesses and vulnerabilities.It is sustained by a community project with the goals of understanding flaws in software and hardware and creating automated tools that can be used to identify, fix, and prevent those flaws.

Discussions of SQL injection, such as a 1998 article in Phrack Magazine, began in the late 1990s. [5] SQL injection was considered one of the top 10 web application vulnerabilities of 2007 and 2010 by the Open Web Application Security Project. [6] In 2013, SQL injection was rated the number one attack on the OWASP top ten. [7]
A web application firewall (WAF) is a specific form of application firewall that filters, monitors, and blocks HTTP traffic to and from a web service.By inspecting HTTP traffic, it can prevent attacks exploiting a web application's known vulnerabilities, such as SQL injection, cross-site scripting (XSS), file inclusion, and improper system configuration.
