The Challenge
Web Applications are very common today, however so are their vulnerabilities. There are many reasons these applications are so insecure. First, many have inadequate Authentication and Authorization which can lead to unauthorized access to sensitive data or functionality. They often have Insecure Dependencies that rely on third-party plugins and open-source code. Additionally, sometimes they lack Encryption so data can be intercepted and stolen. They can also have File Upload Vulnerabilities, allowing users to upload files without proper validation and controls which can lead to malware injection. And of course, there's always the Zero Day, so assessing security routinely is wise.
