Hi,
I am currently developing a Java web application using the Struts 7.0.3
framework, JDK 23, and Tomcat 11.0.5, with a Dynamic Web Module version
6.1. Although the application is intended for an intranet environment, VA
(Vulnerability Assessment) clearance is still required.
To address security concerns, I have implemented a CspInterceptor class.
However, after scanning the application with OWASP ZAP, several
vulnerabilities were reported.
Could you please advise on how to resolve these issues? For your reference,
I have attached the WAR file of the test project along with a few relevant
pages.
Thanks and regards,
Shivam
