Description

WebEx Downloader plug-in contains a flaw that may allow a remote attacker to execute arbitrary commands.

This may allow an attacker to include a DLL file from a remote host that contains arbitrary commands which will be executed by the vulnerable object under the security context of the user viewing the web page.
