Add 2-3 secured implementations for Reflected XSS

[preetkaran20]

Is your feature request related to a problem? Please describe.
As main target for Vulnerable App is scanners so we need to find out false positives by Scanners such that they can improve on there scan rules. So in order to find out the false positives, we need to add more secured implementations.

Describe the solution you'd like
Add 2-3 more functions in https://github.com/SasanLabs/VulnerableApp/tree/master/src/main/java/org/sasanlabs/service/vulnerability/xss/reflected which are secure.

Hi @preetkaran20,

I'm a cybersecurity student, and for my project, I need to work on vulnerabilities in a cybersecurity project. I want to focus on reflected XSS and implement 2–3 secure ways to prevent it, and help scanners as you said.

Hi @preetkaran20,

Thank you for assigning me the issue. Before submitting a pull request, I have worked on the implementation, which you can review in my forked repository: https://github.com/LyesRocker/VulnerableApp/blob/master/src/main/java/org/sasanlabs/service/vulnerability/xss/reflected/XSSInImgTagAttribute.java

Let me know your thoughts on it. If everything looks good, I'll proceed with issue #408.

Thanks,
Lyes
