The remote Microsoft Exchange Server is missing a security update. It is, therefore, affected by multiple vulnerabilities :
Multiple cross-site scripting (XSS) vulnerabilities exist in Microsoft Exchange Outlook Web Access (OWA) due to improper validation of user-supplied input in web requests. An unauthenticated, remote attacker can exploit these, via a specially crafted link, to execute arbitrary script code in a user’s browser session.
(CVE-2017-8559, CVE-2017-8560)
A cross-site redirection vulnerability exists due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to follow a link, to cause the user to load a malicious website, which then can be used to conduct further attacks. (CVE-2017-8621)
