The remote host is running Microsoft Outlook Web Access (OWA) 2003.
Due to a lack of sanitization of the user input, the remote version of this software is vulnerable to URL injection that can be exploited to redirect a user to a different, unauthorized web server after authenticating to OWA. This unauthorized site could be used to capture sensitive information by appearing to be part of the web application.
