TITLE:
Trend Micro OfficeScan 8.0 Policy Server Denial of Service

SECUNIA ADVISORY ID:
SA29151

VERIFY ADVISORY:
http://secunia.com/advisories/29151/

CRITICAL:
Less critical

IMPACT:
DoS

WHERE:
>From local network

SOFTWARE:
Trend Micro OfficeScan Corporate Edition 8.x
http://secunia.com/product/14630/

DESCRIPTION:
Luigi Auriemma has discovered a vulnerability in Trend Micro
OfficeScan, which can be exploited by malicious people to cause a DoS
(Denial of Service).

The vulnerability is caused due to an error in PolicyServer.exe and
can be exploited to cause the service to terminate via a HTTP request
to the cgiABLogon.exe CGI module with a specially crafted, overly long
"pwd" parameter. The service then restarts after a few seconds.

Successful exploitation requires that the Trend Micro Policy Server
for Cisco NAC is installed.

Other errors e.g. NULL-pointer dereference errors in certain CGI
modules when handling HTTP requests containing certain characters or
with invalid "Content-Length" headers have also been reported.

The vulnerability is confirmed in version 8.0 with Patch 2 build
1189. Other versions may also be affected.

SOLUTION:
Restrict network access to the web service.
