Title: WhizBang Matrix Screen Saver Password Bypass Vulnerability
Severity: MODERATE
Description:
The Matrix screen saver application (available from a number of sites including www.screentime.com, www.whatisthematrix.warnerbros.com, etc.) may be configured to disallow unauthorized users to access system resources without a password. This is possible using the Password Protected checkbox in the Display Properties of Windows.
A flaw exists in the Matrix screen saver. If the Password Protected checkbox has been enabled, it is possible to bypass it by clicking cancel and pressing numerous arbitrary keys.
It is not confirmed that the Matrix screen saver is using Windows authentication, it is believed that the authentication mechanism being used is the one included with the Matrix screen saver application.
If the screen saver is running under the context of the logged-on system user, the attacker will only have access to resources to which the logged-on system user has access.
Successful exploitation of this vulnerability could lead to the disclosure of sensitive information, possibly assisting in further compromise of the system.
This issue has been confirmed to be vulnerable on Windows 95, 98 and Me.
