Synopsis

An application installed on the remote Mac OS X host is affected by multiple remote code execution vulnerabilities.

Description

The remote Mac OS X host is running a version of Microsoft Office that is affected by several vulnerabilities.

If an attacker can trick a user on the affected host into opening a specially crafted Office file, these issues could be leveraged to execute arbitrary code subject to the user's privileges.

Solution

Microsoft has released a set of patches for Office for Mac 2011, Office 2008 for Mac, Office 2004 for Mac, and Open XML File Format Converter for Mac.

How to Run

Here is how to run the MS11-021 / MS11-022 / MS11-023: Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (2489279 / 2489283 / 2489293) (Mac OS X) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select MacOS X Local Security Checks plugin family.
On the right side table select MS11-021 / MS11-022 / MS11-023: Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (2489279 / 2489283 / 2489293) (Mac OS X) plugin ID 53374.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl macosx_ms_office_apr2011.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a macosx_ms_office_apr2011.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - macosx_ms_office_apr2011.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state macosx_ms_office_apr2011.nasl -t <IP/HOST>

Go back to menu.
