Vulnerability Note VU#22919

Original Release Date: 2000-11-02 | Last Revised: 2000-11-02



The SystemWizard "Registry Object" ActiveX Control may allow attackers to modify the registry on systems where the control is installed. 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.
