Re: [Kerio 4.x] port 44334 is OPEN: BIG SECURITY HOLE
Kerio uses that port for -all- admins, local admin being accomplished via a loopback... and it isn't an unsound way to do it, just as long as the developer knows what he's doing and properly secures the administrative ports... problem arises where they're left open, and visible, they become a firewall fingerprint... and if they're left open, and unpassworded, they're an advertisement to get owned.
As far as defending against "half-open" scans, Kerio handled the nMap scans I threw at it over my LAN fairly well, some time back, when I tested it... I may have to try doing it again, with 2.1.5 ... I think it might be interesting to do it with 4.x, sometime, but I would rather wait until something resembling a stable build comes out... and as far as I can see, so far, it ain't here, yet.

Ahh.. they made the worthless ids the component blocking the packet... Funny, how they want you to use a horribly coded ids, but your advanced rules are not able to block the packet. That is if it wasn't blocked by some other source.

Recommendation:
I can confirm that this affects 2.15 as well.
That's right 2.15!
I'm starting a new tread for this one.
