Amir, et al, We would not classify this issue as a security vulnerability. The COM object in question is *NOT* loadable in Internet Explorer in a default configuration. CLSID: {9A077D0D-B4A6-4EC0-B6CF-98526DF589E4} ProgId: vbDevKit.CVariantFileSystem Path to binary: C:\WINDOWS\vbDevKit.dll Doesn't implement IObjectSafety Registry settings: Registry: is not safe for initialization Registry: is not safe for scripting Killbit is NOT set In order to load this control, the particular security setting that would need to be modified is "Initialize and script ActiveX controls not marked as safe for scripting". Changing this particular setting to "Enable", or even "Prompt", significantly impacts the browser's overall security posture. In short, if your machine allows this control to be loaded, then your browser will load controls regardless of safety designations such as "Safe for Scripting", "Safe for Initialization", and "IObjectSaftey". This includes the ability to load controls such as WScript, which can execute arbitrary commands out of the box. iDefense Labs
