Description:

A vulnerability in the Microsoft Help and Support Center HCP URI handler included with Internet Explorer on Windows XP could allow a remote attacker to delete files on another user's computer. A remote attacker could create a specially-crafted HCP:// URL to the uplddrvinfo.htm Help and Support Center page, which contains an ActiveX control that can be used to delete files. If the attacker could convince a victim to click this URL, the attacker could then delete files on the victim's computer.
