| Detailed Description |
The Hotfix(Q832759) for 'Privilege Escalation Vulnerability in Exchange Server 2003' has not been applied.
Microsoft Exchange Server 2003 using the Outlook Web Access (OWA) could allow a remote authenticated OWA user to gain unauthorized access to mailboxes of other users on a vulnerable host. The problem occurs when a user installs Windows SharePoint Services 2.0 on a computer running both Exchange Server 2003 and Microsoft Windows Server 2003. This installation causes Kerberos authentication to be disabled in Internet Information Services (IIS) and can result in incorrect handling of OWA requests to an Exchange Server.
* Note: This check requires an account with Guest or upper privileges which can access the registry of the remote host to scan. Absence of these condition will result in the check not being performed and a False Negative for all vulnerable hosts.

| Recommendation |
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS04-002 at http://www.microsoft.com/technet/security/bulletin/ms04-002.asp
As a workaround, configure Windows SharePoint services to use Kerberos authentication in IIS, listed in http://www.microsoft.com/exchange/support/e2k3owa.asp |
