Analysis on Injection Vulnerabilities of Web Application

The number of Internet users has incredible grown. Web applications are normally utilized in various sectors like Ecommerce, Banking, and Military. It is collection of thousands of lines of program, which habitually contain some bugs. Part of them have impact on security and can lead to complete control of the application by an attacker. While in client-server communication, the attacker inputs the vulnerable content into the application, these unnoticed vulnerabilities cause financial losses to organizations. Thus, mitigating such an attack is vital to evade mischievous penalties. An enormous research work on application security has been continuously going on but every defense has its own advantages and disadvantages. The aim of this paper is to study and consolidate the understanding of injection vulnerabilities and its mitigation technique. Different approaches proposed by researchers are analyzed here and discussed about the observed pitfalls present in the existing solutions.
