Synopsis

The remote host is missing a macOS or Mac OS X security update that fixes multiple vulnerabilities.

Description

The remote host is running Mac OS X 10.12.6 and is missing a security update. It is therefore, affected by multiple vulnerabilities including:

- A malicious application may be able to execute arbitrary code with kernel privileges. (CVE-2019-8555)

- A malicious application may be able to determine kernel memory layout. (CVE-2019-6207, CVE-2019-8510)

- A malicious application may be able to read restricted memory. (CVE-2019-8520)

- 802.1X - DiskArbitration - Feedback Assistant - IOKit - IOKit SCSI - Kernel - PackageKit - Perl - Security - Time Machine - Wi-Fi

Solution

Install Security Update 2019-002 or later for 10.12.x.

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 and Mac OS X Multiple Vulnerabilities (Security Update 2019-002) plugin ID 123129.
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_SecUpd_10_12_6_2019-002.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a macos_SecUpd_10_12_6_2019-002.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - macos_SecUpd_10_12_6_2019-002.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_SecUpd_10_12_6_2019-002.nasl -t <IP/HOST>

Go back to menu.
