Hi,

If it doesn't have a client application cert, indeed it's a
vulnerability. If someone arppoison (well any MiM techniques that
could redirect the traffic to pass through you) could portredirect and
handle the ssl connection. And sniff it son it's not enough just ssl.
Could be done with stunnel, maybe? ;)

I've tested officescan (last version)....weak registry permitions.
ie:
HKLM\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\Misc.\ ->
NoPwdProtect = 1
(will enable to unload without pass, as your product doen't apply
permission on these reg keys)

I remember old versions weak pccsrv sharing permitions (default permission,
everyone fullcontrol I mean, comes to mind...infecting autopcc ?).
Does it still the same?

Cheers,
