We are working on obtaining PCI compliance for our e-commerce website with securitymetrics.com One last item that keeps coming up is as follows:
Synopsis : This web server leaks a private IP address through its HTTP headers. Description : This may expose internal IP addresses that are usually hidden or masked behind a Network Address Translation (NAT) Firewall or proxy server. There is a known issue with IIS 4.0 doing this in its default configuration. This may also affect other web servers, especially on a misconfigured redirection. See also : http://support.microsoft.com/support/kb/ articles/Q218/1/80.ASP
I have implemented the changes in the MetaBase by using the adsutil.vbs script that are documented in the KB articles and have also verified these changes by using the IIS6 metabase explorer, however we continue to fail on this item.
We are reverse hosting this site through a Fortinet firewall.
Any suggestions on something that I may be missing?
