Detail
Vulnerability Note VU#461321HP Virtual Rooms ActiveX control fails to restrict access to dangerous methodsOverviewThe HP Virtual Rooms ActiveX control contains methods that can be used to download and execute arbitrary code from an arbitrary server.I. DescriptionHP 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.II. ImpactBy 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.III. SolutionApply an updateThis 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:
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerActiveX Compatibility{00000032-9593-4264-8B29-930B3E4EDCCD}] "Compatibility Flags"=dword:00000400 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. Systems Affected
