The Acer AcerCtrls.APlunch ActiveX control contains methods that can allow a remote, unauthenticated attacker to run arbitrary commands on a vulnerable system.
The Acer AcerCtrls.APlunch ActiveX control is provided by acerctrl.ocx. It contains a method called Run(), which takes two parameters: Drive and FileName. Although the control is not inherently marked as safe for scripting via the IObjectSafety interface, it may be distributed with the appropriate Implemented Categories registry key to make it safe for scripting. This means that a web page in Internet Explorer can call the Run() method of the control.
Note that this vulnerability is similar to but not the same issue as VU#221700. This control has different parameters and uses a different CLSID that is not included in the killbits provided with Microsoft Security Bulletin MS07-027.
By convincing a victim to view an HTML document (web page, HTML email, or email attachment), an attacker could run arbitrary commands with the privileges of the user running IE.
We are currently unaware of a practical solution to this problem. Please consider the following workarounds:
