We are a portal provider for non-profits online giving.  As such we come under PCI rules and periodically are scanned for security vulnerabilities.   The scans are showing "IP address is revealed in the content-location field in the TCP header" and the suggested fix is to use Microsoft KB 834141.  However that breaks dnn.

How do we fix this?

thanks,
scott

Hello,

I wasn't aware of this issue, and I definately don't think it's very common as the patch is a few years old and this is only the second time I've seen a report of problems. I did a bit of searching and it seems that a number of machines running SSL or with outlook web access had problems with this patch (or wide code that uses request.issecureconnection ). You could try searching for that term in the code and setting breakpoints on it and seeing if that is your issue.

During the time searching the only note I found of someone resolving the issue without backing the patch out was the following (bottom of the page posts)http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_23461181.html

Thanks for the pointer but that resolves back to the same suggestion to set the hostname in IIS.  The problem is that breaks the dnn aliasing.  The big time issue we're faced with here is that  If we can't pass the security scans then we have to find a different solution than dnn.  I'd rather stay with dnn but I need a pointer on where to patch this.  Since it's in the host headers going back I'm really at a loss.
