HSC enables users to learn about Windows features, download and install software updates, get assistance from Microsoft and so forth. A remote attacker could exploit this issue by convincing a user to open a maliciously crafted HTML file with Internet Explorer, which may allow the attacker to execute arbitrary code on the affected system. The vulnerability is due to an error in the Windows Help and Support Center that fails to properly validate URLs when using the HCP Protocol.
