------------------------------------------------------------------------


SUMMARY


<http://www.trendmicro.com/en/products/file-server/sp-linux/evaluate/overview.htm> Trend ServerProtect is an Anti-virus application designed to run on file servers to catch viruses before they make it to network users.

Exploitation of this vulnerability allows a remote attacker to edit and
disable Anti-Virus features on the server machine.

DETAILS

Vulnerable Systems:
* Trend ServerProtect version 1.3 for Linux.
* This vulnerability is not present in the Windows based versions of
Server protect.

TrendMicro's ServerProtect product uses a web interface which runs on port
TCP 14942 to configure the product. This interface is protected with a
user configurable password. Upon successful login, a cookie is set with
the name 'splx_2376_info' and a valid session id as its value.

vulnerability in its authorization checking routines. Attackers can gain
full access to the web application by requesting any internal page while
supplying their own 'splx_2376_info' cookie with an arbitrary value.

iDefense recommends limiting network access to the ServerProtect web
interface to trusted clients.
