Subject: Re: Forticlient VPN client credential
interception vulnerability
Reminded me of a bug I found in an EAL4 certified military encryption product.
The source code actually says "FIXME - need to add parameter validation."
So instead of spending a few minutes adding input sanitisation, the
developers just added a reminder that none exists and shipped the
product as-is. One of those face slap moments.
