Who is Vulnerable?
Vulnerability Description Outlook Web Access (OWA) is a webmail service of Microsoft Exchange Server 5.0 and later. The web interface of OWA resembles the interface in Microsoft Outlook. An elevation of privilege vulnerability was reported in Microsoft Outlook Web Access. The vulnerability is due to an error in Outlook Web Access, which under certain circumstances allows an authenticated OWA session to be hijacked by an attacker. A remote attacker may exploit this issue by convincing a user to visit a malicious Web page that the attacker crafted specifically for the targeted Exchange domain, during an active OWA session. Successful exploitation of this issue could allow the attacker to perform actions on behalf of the authenticated user in the security context of the active OWA session, such as reading e-mail messages, adding new inbox rules, or changing OWA user preferences.
