Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing a security update. It is, therefore, affected by multiple cross-site scripting vulnerabilities in Skype for Business Server and Lync Server :

- A cross-site scripting vulnerability exists in Skype for Business Server and Lync Server due to a failure by the jQuery engine to properly sanitize specially crafted content. An unauthenticated, remote attacker can exploit this vulnerability by convincing a user to open a malicious URL, resulting in the execution of arbitrary script code in the user's browser to gain information from web sessions. (CVE-2015-2531)

- A cross-site scripting vulnerability exists in Lync Server due to improper sanitization of specially crafted content. An unauthenticated, remote attacker can exploit this vulnerability by convincing a user to open a malicious URL, resulting in the execution of arbitrary script code in the user's browser to gain information from web sessions. (CVE-2015-2532)

- A cross-site scripting vulnerability exists in Skype for Business Server and Lync Server due to improper sanitization of specially crafted content.

(CVE-2015-2536)
