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? ;)

We thank you for pointing out this to us and we are grateful that our
products are "checked" for security issues! We can sometime like in this
case just assume that all think of security issues but the truth is that
IT personal have more than security to think about. So things like this
are constantly missed!

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,
   shadown

Dear Bugtraq,

Here is Trend Micro's reply to this claim

This kind of sniffing and "hijacking" of login could be done to almost
all ordinary installed http products with login procedure.
Since we offer a way to install it with HTTPS(SSL) and making login and
communicating with the server secure, we have a internal discussion
about if we should call this a "Vulnerability" or not.
We have made the R&D promise that next version will be with the question
in the installation program for installing SSL support.
On the other hand this product should be installed by IT professionals.
And it should be obvious to them that IIS in http mode is not security
enough.

Subject: Trend Micro Control Manager - Enterprise Edition 3.0 Web
application Replay attack
Date: Thu, 13 Jan 2005 19:45:53 +0100
X-Mailer: Microsoft Outlook, Build 10.0.6626

The web application are vulnerable to a replay attack, meaning that the

username and password are encrypted but there are not used any form of
timestamp to make this mechanism more advanced and secure.

If it is possible to sniff the traffic when a user login to the
administrative interface, it is possible to replay this sequence and
get a valid login session, with the rights of the user.

Vendors response to this was, it is a feature not a vulnerability and
all the others also have this problem.
