Sasikumar;
What tool are you using for your PCI scan? That doesn't sound like something from our team so I don't think I can provide you with much help without a lot more information. What are the details of the issue from the scanner's report? What does the report
say you should do to address the vulnerability? Have you contacted the vendor of the scanner with your question?
Regards,
Kurt
