Thousands of web application vulnerabilities have been reported so far and cyber security analysts are continuously working to protect web applications from security attacks. The Open Web Application Security Project (OWASP) helps security professionals find and combat against web application vulnerabilities and attacks. They designed the web security vulnerabilities assessment tool (ZAP), guidelines for testing the webserver against vulnerabilities and also classifies web application attacks. Some of the critical and common web application vulnerabilities are: Injection vulnerabilities, Authentication weaknesses, Cross Site Scripting, Sensitive Data Exposure, Unvalidated redirects and directory traversal attacks. A detailed description of some of these vulnerabilities are discussed on the following pages.
