MS15-110: Security Updates for Microsoft Office to Address Remote Code Execution (3089440)

This script is Copyright (C) 2015-2017 Tenable Network Security, Inc.


Synopsis :

The remote Windows host is affected by multiple vulnerabilities.

Description :

The remote Windows host has a version of Microsoft Office, Excel,
Excel Viewer, SharePoint Server, Microsoft Office Compatibility Pack,
or Microsoft Office Web Apps installed that is affected by multiple
vulnerabilities :

- Multiple remote code execution vulnerabilities exist due
to improper handling of objects in memory. A remote
attacker can exploit these vulnerabilities by convincing
a user to open a specially crafted file, resulting in
execution of arbitrary code in the context of the current
user. (CVE-2015-2555, CVE-2015-2557, CVE-2015-2558)

- An information disclosure vulnerability exists in the
SharePoint InfoPath Forms Services due to improper
parsing of document type definitions (DTD) in XML files.
A remote attacker can exploit this, via a crafted XML
file, to browse the contents of arbitrary files on a
SharePoint server. (CVE-2015-2556)

- An cross-site scripting vulnerability exists in Office
Web Apps Server due to improper sanitization of crafted
requests before returning it to the user. A remote
attacker can exploit this to run arbitrary script code
in the user's browser session. (CVE-2015-6037)

- A security feature bypass vulnerability exists in
SharePoint due to improper enforcement of permission
levels for applications or users. This allows Office
Marketplace to inject JavaScript code that will persist
in a SharePoint page. A remote attacker can exploit this
to conduct a cross-site scripting attack, resulting in
execution of arbitrary code in the user's browser
session. (CVE-2015-6039)
