Synopsis

The remote host is missing a macOS update that fixes multiple security vulnerabilities.

Description

The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.4. It is, therefore, affected by multiple vulnerabilities, including:

- Mounting a maliciously crafted NFS network share may lead to arbitrary code execution with system privileges. (CVE-2019-8508)

- An application may be able to execute arbitrary code with kernel privileges. (CVE-2019-8529)

- A malicious application may be able to execute arbitrary code with system privileges (CVE-2019-8549)

Solution

Upgrade to macOS version 10.14.4 or later.

How to Run

Here is how to run the macOS 10.14.x < 10.14.4 Multiple Vulnerabilities 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 macOS 10.14.x < 10.14.4 Multiple Vulnerabilities plugin ID 123128.
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 macos_10_14_4.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a macos_10_14_4.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - macos_10_14_4.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 macos_10_14_4.nasl -t <IP/HOST>

Go back to menu.
