First, make a note: after Adobe updates, restart your machine immediately to remove the Adobe Download Manger – it can be a vector for malcode.

Now, back to our story.

Aviv Raff has discovered a vulnerability with Adobe’s web site in combination with its Download Manager, an ActiveX script that is used to download updates for Reader and Flash. After a Reader or Flash update the download manager remains running on a user’s machine until it is rebooted. Malicious operators could exploit it to download their code of choice.

Raff demonstrated the flaw by using the download manager to download a copy of Windows calculator.

He has notified Adobe of the problem but not publically disclosed the finer details vulnerability.
