Additional Information

The vulnerability exists in Akamai Download Manager ActiveX control when parsing a parameter which is passed to it. A remote attacker could craft a malicious Web page to exploit the control, which would result in a file being downloaded to an arbitrary location on a user's system once visiting the site. An attacker who successfully exploits this vulnerability can then run arbitrary code on the user's system. For example, a malicious file could be downloaded to a users "startup" folder which would then execute on system boot-up. The arbitrary location must be a valid path, or the file will not download. When a valid path is used, the file will be downloaded in a "drive-by" nature without any user interaction required.
