Synopsis

An application installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The Microsoft SharePoint Server or Project Server installed on the remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :

- A remote code execution vulnerability exists in Microsoft Office due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website or open a specially crafted document, to execute arbitrary code in the context of the current user. (CVE-2017-0243)

- A remote code execution vulnerability exists in Microsoft Office due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website or open a specially crafted document, to execute arbitrary code in the context of the current user. (CVE-2017-8501)

- A cross-site scripting (XSS) vulnerability exists in Microsoft SharePoint Server due improper validation of user-supplied input in web requests. An authenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-8569)

Solution

Microsoft has released a set of patches for SharePoint Server 2013 and 2016; Excel Services on SharePoint Server 2010; and Microsoft Project Server 2010.
