This signature detects attempts to use unsafe ActiveX controls in Yahoo Messenger CYFT. An attacker can create a malicious Web site containing Web pages with dangerous ActiveX controls, which if accessed by a victim, allows the attacker to gain control of the victim's client browser.
Yahoo! Messenger CYFT ActiveX control is prone to an arbitrary-file-upload vulnerability because it fails to adequately sanitize user-supplied input. Successfully exploiting this issue allows an attacker to upload malicious files to an arbitrary location on a victim's computer; the files will have the permissions of the application using the ActiveX control (typically Internet Explorer). Yahoo! Messenger 8.1.0.421 is vulnerable; other versions may also be affected.
