Who is Vulnerable?
Vulnerability Description Microsoft Outlook Web Access (OWA) is a component of Microsoft Exchange Server. OWA allows authorized users to send and receive email, manage a calendar, and perform other functions using a web browser. OWA utilizes HTML, CSS and scripting techniques to present the user interface through the web browser. OWA is primarily implemented using Active Server Page (ASP), served using the web server component of Microsoft Internet Information Server (IIS). The dynamically generated web pages also contain client-side script code to implement mail message administration functionality. A cross-site scripting vulnerability exists in the Outlook Web Access component of Exchange Server 5.5. The flaw is caused by an insufficient sanitization of user's email messages. A malicious user can leverage this flaw to inject and execute script code in the security context of the current user email account. A successful attack exploiting this vulnerability can inject malicious script code into the OWA session. An attacker can read or delete email, access the user's contact list and other operations on the user's mail account. The attacker can fully control the compromised mail account. The malicious script could also take actions on the user's computer in the security context of the OWA web site.
