MW6 Technologies ActiveX controls contain multiple vulnerabilities

Overview

MW6 Technologies’ MaxiCode, Aztec, and DataMatrix ActiveX controls contain multiple vulnerabilities.

Description

MW6 Technologies’ MaxiCode, Aztec, and DataMatrix ActiveX controls are used for processing barcodes. The ActiveX controls contain multiple vulnerabilities that may lead to remote code execution.

---

Impact

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

---

Solution

We are currently unaware of a practical solution to this problem. Please consider the following workarounds.

---

Disable the ActiveX control in Internet Explorer

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

* {2355C601-37D1-42B4-BEB1-03C773298DC8}
* {F359732D-D020-40ED-83FF-F381EFE36B54}
* {DE7DA0B5-7D7B-4CEA-8739-65CF600D511E}

More information about how to set the kill bit is available in Microsoft Support Document 240797.

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.
