Vulnerability Note VU#784369

Trend Micro OfficeScan Web-Deployment SetupINICtrl ActiveX control buffer overflows

Original Release date: 20 Feb 2007 | Last revised: 20 Feb 2007

Overview

The Trend Micro OfficeScan Web-Deployment SetupINICtrl ActiveX control contains multiple buffer overflows, which could allow a remote attacker to execute arbitrary code on a vulnerable system.

Description

Trend Micro OfficeScan comes with a web-based administration console that makes use of ActiveX controls. The OfficeScan Web-Deployment SetupINICtrl ActiveX control, which is provided by the file OfficeScanSetupINI.dll, is vulnerable to buffer overflows in multiple methods. It is reported that Client Server Messaging Security for SMB also contains the vulnerable control.

Impact

By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user. The attacker could also cause Internet Explorer (or the program using the WebBrowser control) to crash.

Solution

Apply an update

This issue addressed in Trend Micro support document 1034288. This document provides the following fixed versions:

  • OfficeScan 7.0 - Build 1344
  • OfficeScan 7.3 - Build 1241
  • Client / Server / Messaging Security 3.0 - Build 1197

Disable the OfficeScan SetupINI ActiveX control in Internet Explorer

The vulnerable ActiveX control can be disabled in Internet Explorer by setting the kill bit for the following CLSID:

    {08D75BB0-D2B5-11D1-88FC-0080C859833B}
More information about how to set the kill bit is available in Microsoft Support Document 240797. Alternatively, the following text can be saved as a .REG file and imported to set the kill bit for this control:
    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{08D75BB0-D2B5-11D1-88FC-0080C859833B}]
    "Compatibility Flags"=dword:00000400
Disable ActiveX

Disabling ActiveX controls in the Internet Zone (or any zone used by an attacker) appears to prevent exploitation of this and other ActiveX vulnerabilities. Instructions for disabling ActiveX in the Internet Zone can be found in the "Securing Your Web Browser" document.
