Security Update for Microsoft SharePoint Server (June 2017)

High Nessus Plugin ID 100787

Synopsis

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

Description

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

- Multiple remote code execution vulnerabilities exist in Microsoft Office due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these, by convincing a user to open a specially crafted document, to execute arbitrary code in the context of the current user. (CVE-2017-8509, CVE-2017-8511, CVE-2017-8512)

- A remote code execution vulnerability exists in Microsoft PowerPoint due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted file, to execute arbitrary code in the context of the current user. (CVE-2017-8513)

- A reflective cross-site scripting (XSS) vulnerability exists in Microsoft SharePoint Server due improper validation of user-supplied input in web requests. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-8514)

- An elevation of privilege vulnerability exists when Microsoft SharePoint Server does not properly sanitize a specially crafted web request to an affected SharePoint server. An authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected SharePoint server. (CVE-2017-8551)

Solution

Microsoft has released a set of patches for SharePoint Server 2007;
SharePoint Server 2010; SharePoint Enterprise Server 2013 and 2016;
SharePoint Foundation 2013; Word Automation Services on Microsoft SharePoint Server 2010; and Microsoft Office Project Server 2013.
