The IBM Access Support ActiveX control contains a stack buffer overflow, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
The IBM Access Support ActiveX control has the ability to collect system information, such as make, model, serial number, OS version, etc. This control is available on the IBM / Lenovo web site, and also may come pre-installed on IBM and Lenovo computer systems. The IBM Access Support ActiveX control, which is provided by IbmEgath.dll, contains a stack buffer overflow in the GetXMLValue() method. We have confirmed that version 3.20.284.0 is vulnerable. Other versions may also contain the flaw.
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.
We are currently unaware of a practical solution to this problem. Please consider the following workarounds:
Disable the IBM Access Support ActiveX control in Internet Explorer
