New! Plugin Severity Now Using CVSS v3

The remote host is affected by a cross-site scripting vulnerability.


The remote Windows host is affected by a cross-site scripting (XSS) vulnerability in Skype for Business and Lync clients due to improper sanitization of message content before returning it to the user. A remote attacker can exploit this, using specially crafted JavaScript, to execute arbitrary script and HTML in the user's context, resulting in the possible disclosure of sensitive information or other actions.


Microsoft has released a set of patches for Lync 2010, Lync 2010 Attendee, Lync 2013, Lync Basic 2013, Skype for Business 2016, Skype for Business Basic 2016, and Lync Room System.
