MS13-073: Vulnerabilities in Microsoft Excel Could Allow Remote Code Execution (2858300))

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

It is possible to execute arbitrary code on the remote host through
Microsoft Excel.

Description :

The remote Windows host is running a version of Microsoft Excel that
is affected by the following vulnerabilities :

- Two memory corruption vulnerabilities exist due to the
way the application handles objects in memory when
parsing Office files. (CVE-2013-1315 / CVE-2013-3158)

- An information disclosure vulnerability exists due to
the way the application parses XML files containing
external entities. (CVE-2013-3159)

If an attacker can trick a user on the affected host into opening a
specially crafted Excel file, it may be possible to leverage these
issues to read arbitrary files on the target system or execute
arbitrary code, subject to the user's privileges.
