The HP Virtual Rooms ActiveX control contains methods that can be used to download and execute arbitrary code from an arbitrary server.
HP Virtual Rooms is software for online collaboration. HP Virtual Rooms requires Internet Explorer, as one of the components is an ActiveX control called HPVirtualRooms32, which is provided by the file HPVirtualRooms32.dll
. The HPVirtualRooms32 ActiveX control contains dangerous methods, but does not place any restrictions on which web sites can use the control. These methods can be used to download and execute arbitrary code from an arbitrary server.
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.
Apply an update
This issue is addressed with the HP Virtual Rooms client 7.01. This update sets the kill bit for the vulnerable version of the ActiveX control, while providing an updated version with a different CLSID. Please see the HP Virtual Rooms 7.01 release notice for more details. This control is also disabled in Internet Explorer with the update for Microsoft Security Advisory (969898). Please also consider the following workarounds:
Disable the HPVirtualRooms32 ActiveX control in Internet Explorer
The vulnerable ActiveX control can be disabled in Internet Explorer by setting the kill bit for the following CLSID:
{00000032-9593-4264-8B29-930B3E4EDCCD}
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\{00000032-9593-4264-8B29-930B3E4EDCCD}]
"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.
