Re: Vista x32 IE7 SSL Security Problem

Thankyou Robear.

I have previously reset the IE settings as per the KB article and
unfortunately that didn't fix it. I did it again anyway and I don't have 256
aes SSL and the other problems. I gave the no add on ie process a whirl and
still no 256 aes in SSL.

I ended up caving in to Microsoft and paying the support fee via my partners
credit card with the understanding that when hopefully its proven to be a
bug I can get my money back. When I eventually got onto the tech who was
helping me it ended up being unresolved and he indicated he would need to
investigate further and get back to me. In safe mode I get no 256 aes but
interestingly the event viewer syslog error and warning problem events don't
occur - then however if you disable all startup programs and all non MS
services on reboot the events do re-occur.

This has been going on for awhile and I recently wiped my partition after I
suspected my computer had been compromised. The reinstall of Vista x32
ultimate didn't help obviously.

FWIW I'm running the OneCare live beta, but as I mentioned previously I've
also ran Kasperskys online scanner (which is widely regarded to have the
highest detection rate in the industry) and a whole bunch of AntiSpyware
programs which all found nothing.

I've been enjoying Roger Grimes book on Vista security and its pleasing that
Vista is so much better than previous desktop OS's MS has released. Frankly
I don't like the usability of Firefox's gran paradiso and I think IE7 offers
better phishing protection, nicer usability and the protected mode security.
Its a bit ironic though that as soon as I tried gran paradiso it immediately
did 256 aes SSL and I have no alarming preference changes mysteriously
enabling insecure things like sslv2.

There's no real alternative - BSD / Linux is a nightmare for general use and
MacOS is tied to hardware that doesnt suit me. MS has gotten its act
together pretty well since Dos/Win95 and I hope this security problem is
just a small bump in the years I'll be using this operating system.

Well, Im sticking at this. I have not heard back from MS support, but I
think now I have enough evidence to get my money back on the support fee
they charged me.

What I did was wipe my partition again, and re-install Vista x32. I'm
usually careful, this time I was super careful about what device drivers and
applications I installed. I also made a point to patch the security hotfixes
from windowsupdate before doing anything.

So with the system up I start IE7, again no 256 bit AES. I've been trying to
get someone in the USA with a USA IP on Vista and IE7 to check what ssl
cypher strength they get from (want to clarify a cypher export thing I was
thinking of):

https://www.fortify.net/sslcheck.html

No one has so far cos I think people who dont know better think its some
sort of trap. Would someone try this and tell me the result please.

Then, I closed all my apps and re-opened IE7, confirming that only TLS was
enabled in advanced options and that SSLv2 and SSLv3 were not. Double
checked the setting again. Then I closed IE, no other apps running, only
system services and processes. Woke up in the morning knowing for sure no
user interaction had occured, and I find that SSLv2 and SSLv3 have now
mysteriously been enabled.

With default IE7 settings I got this:
You have connected to this web server using the AES128-SHA encryption cipher
with a key length of 128 bits

Thanks Jane but it would appear your in Australia like me (based on your
email addy)

The reason I'm hoping for someone in the USA with a USA IP on Vista IE7 is
to rule out any cipher export restrictions that might be limiting the cipher
strength. So would someone that fits that situation please report what they
get.

This just gets worse. After some days of not hearing from MS support I
decide to contact them.

They email me this nonsense about IE7 and SSL from the IE7 blog. Swalling my
frustrations I try to explain that does not contribute anything to the
resolution and is actually pointing out that the support tech doesnt
understand the issues at hand. I actually read that blog entry as part of
the research I did before caving into MS demands for paying a support fee
cos all it does is confirm that what is happening should not be
happening.....So glad I got quality support for my money!

Then I get a response back from the MS support tech asking for sceenshots.
I'm agitated at this time cos I already supplied them many screenshots days
ago that clearly showed what they are now asking for. Go Microsoft support!
I havent had any response about what tangible progress has been made and
where my incident was escalated too.

I will be pushing them for a refund on my support fee cos clearly its a bug.
I've twice now wiped my partition and re-installed. They agreed up front
they would refund the fee when I show its a bug.

I go out of my way to talk up Vista and I'm really a fan of what MS is doing
these days but this experience doesnt taste good!

From the USA...

Vista Ultimate with IE7
You have connected to this web server using the AES128-SHA encryption cipher
with a key length of 128 bits.

XP-Pro with IE6
You have connected to this web server using the RC4-MD5 encryption cipher
with a key length of 128 bits.

Regards,
-Seth

Total legend Seth, thankyou very much. So it looks like IE7 on Vista is
bugged when it comes to 256 biit aes cipher lengths.

Not pretending to know anything about the intricacies behind encryption, my
XP/IE6 machine also showed 128. A different method (RC4 instead of AES) but
still 128.

Re: Vista x32 IE7 SSL Security Problem

I apologize for the troubles you've been having. The reason you see AES
128-bit rather than AES 256-bit is because of the default order that the
operating system presents for cipher suites. Vista offers AES 128-bit first
in order to minimize performance impacts, so the server selects that. AES
128-bit is more than sufficient for protecting information.

However, if you'd like to change the default offering order, here's how to
do it:

1. Open your group policy editor by entering "gpedit.msc" at a command
prompt.
2. Choose "Computer Configuration | Administrative Templates | Network | SSL
Configuration Settings."
3. There's only one item here: "SSL Cipher Suite Order." Open it.
4. Select "Enabled."
5. Now here's where you need to tread carefully. The first item in the list
is:
TLS_RSA_WITH_AES_128_CBC_SHA
And the second item is:
TLS_RSA_WITH_AES_256_CBC_SHA
Cursor your way through the list. Change that first "128" to "256." Then
cursor forward a bit more and change the "256" to "128."
6. "OK" your way out, close the group policy editor, and reboot.

I'm looking into getting a KB article to document this, and also will see
about making sure the support folks know about it too.
