Original Release date: 02 Nov 2000 | Last revised: 02 Nov 2000

This control was shipped on HP Pavilion computers running Windows 98, as part of a diagnostic application named "SystemWizard" produced by SystemSoft. This control can be used to read and write registry keys without authentication. Because the control is marked safe-for-scripting, this vulnerability can be exploited via a web page if the user has the vulnerable control installed.

This control is implemented in the file reg.dll and has a ClassID of {9C3558B8-4175-11D0-926E-00AA00B91D12}. The control can also be referenced as IISSample.RegistryAccess.
