TITLE:
Trend Micro OfficeScan CGI Module and Policy Server Buffer Overflows

SECUNIA ADVISORY ID:
SA29124

VERIFY ADVISORY:
http://secunia.com/advisories/29124/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From local network

SOFTWARE:
Trend Micro OfficeScan Corporate Edition 7.x
http://secunia.com/product/5007/

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

1) A boundary error in cgiChkMasterPwd.exe can be exploited to cause
a stack-based buffer overflow via an HTTP request with a specially
crafted, overly long "TMLogonEncrypted" parameter.

Successful exploitation allows execution of arbitrary code.

2) A boundary error in PolicyServer.exe can be exploited to cause a
stack-based buffer overflow via an HTTP request to the cgiABLogon.exe
CGI module with a specially crafted, overly long "pwd" parameter.

Successful exploitation allows execution of arbitrary code but
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 vulnerabilities are confirmed in version 7.3 with Patch 3 build
1314. Other versions may also be affected.

SOLUTION:
Restrict network access to the services.
