Webex Meeting Manager ActiveX Control Vulnerability

August 11th, 2008 . by DarkFiber Consulting

DarkFiber Consulting is aware of public reports of a vulnerability that affects Webex Meeting Manager. This vulnerability is due to improper handling of arguments passed to the “NewObject()” method within the WebexUCFObject ActiveX control (atucfobj.dll). By convincing a user to visit a specially crafted web page, a remote attacker may be able to execute arbitrary code.

Public reports indicate that Webex has addressed this issue in Meeting Manager version 20.2008.2606.4919. DarkFiber Consulting encourages users to upgrade to this version or set the kill bit for CLSID 32E26FD9-F435-4A20-A561-35D4B987CFDC. Information about how to set a kill bit can be found in Microsoft Support Article 240797.
