Trust Boundary Violation - while triggering veracode

Enumeration params = req.getParameterNames();

                String sPrefix = "prefix_";

                while (params.hasMoreElements())

                {

                    String paramName = (String) params.nextElement();

                    if (paramName.startsWith(sPrefix))

                    {

                        String value = (Tool.getValue(req.getParameter(paramName)));

                        try {

                        session.setAttribute(ESAPI.validator().getValidInput("SafeCheckString",paramName,"SafeCheckString",1024,true), ESAPI.validator().getValidInput("SafeCheckString",value,"SafeCheckString",1024,true));//flaw

                        }

I'm getting trust boundary violation in the code (session.setAttribute(....) while triggering veracode.

How can i solve this.

Currently we have few trust boundary violation (CWE ID 501) flaws in our application. The recommended solution to fix this was to validate the input against a regex. Thus, we used ESAPI.validator.getValidInput() API. but the flaws are still not getting mitigated.
