Microsoft Outlook Web Access with RSA SecurID Authentication Bypass Vulnerability

RSA SecurID is a two factor Authentication system, designed to allow remote authentication to a variety of resources through the usage of an authenticator in conjunction with a user password. Microsoft Outlook Web Access (OWA) is a component of Microsoft Exchange Server, used to provide a web interface for email.

Reportedly, a user able to access the OWA system after proper SecurID authentication may then attempt to access OWA as a different user without providing additional SecurID authentication. A valid user and password is still required for both OWA authentication attempts.

Although an error message is displayed, multiple attempts will reportedly result in access to the OWA system.
