WebGUI webserver will not protect a client from the BEAST attack

jimp

It isn't really even Apple in general, all my other Apple tests were OK (iOS and OS X) so it could be specific to that laptop, that version of OS X, or something else.

Until we get some more feedback from others, anything is speculation.

Can you hit that same firewall with any other browser on another OS?
Can you run a firmware upgrade on it again (using ssh or the console) to see if anything is different?

I just put my 10.6.8 iMac on it. Same thing using Firefox.

Grabbed a random laptop. Vista. IE says it can't connect and Firefox gives me the same ssl_error_bad_mac_read.

Looks like it's something on this pfSense install.

I am going to save my config (in case anyone needs to see it later), wipe the config, reconfigure and see what happens.

If it still exhibits the same behavior I'll re-flash the CF from the latest snapshot and try it again.

Erasing the config and starting over did not fix it.

So I took the Soekris home and reimaged the CF with gzcat pfSense-2.1-RC0-4g-i386-nanobsd-20130717-1018.img.gz | dd of=/dev/disk4 bs=64k

On my first connection to http://192.168.1.1/ I am redirected to 443, prompted to confirm the self-signed certificate, and get ssl_error_bad_mac_read.

Maybe this is nanobsd specific? HIFN specific?

All I know is it isn't working for me on this hardware since the BEAST fix was merged.

For grins I removed the HIFN card and tried it again. Worked fine.

Replaced the HIFN card, failed again.

I think it's something to do with HIFN somehow.

Aha, that could be it. Wouldn't be the first time a crypto card caused something like that to happen.

The Hifn card may not like the cipher being chosen by default.

I guess I'll have to put in a checkbox somewhere and restore the old behavior by default with a note about some crypto accelerators not supporting it.

I have a Hifn card here somewhere but it's not currently in my ALIX. I can swap it in and test.

jimp

Yep, I put the Hifn in and the GUI won't load. Easy to reproduce it that way.

jimp

OK it's now off by default and a checkbox option:
https://github.com/pfsense/pfsense/commit/30adceda1fffe160d18bdcbcaccb0da5de000fdf

I have the code disable the option in the GUI if it detects a Hifn card and also if the option is somehow set (restoring a config?) and it detects a Hifn card it will refuse to honor the option.

Should result in a working GUI no matter how someone tries to break it. :-)

All works for me now. Thanks.

Interesting, I found this thread after hitting the problem 7-16, I fixed it by logging in through ssh and manually entering the update url for the 14th. I was checking back today to see if the problem was solved. And yes I do have a Hifn 7955 in an Alix.6e1 that it was installed on, I didn't test pulling the card out to see if it fixed it, as I didn't expect that to be an issue.

@dhatz:

After changing lighttpd config file to include:

ssl.cipher-list = "ECDHE-RSA-AES256-SHA384:AES256-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH:!AESGCM"
ssl.honor-cipher-order = "enable"

Hello

A question: Why do you actually disallow AESGCM instead of putting it at the very front of the cipher order?
