Synopsis

The remote Windows host is affected multiple vulnerabilities.

Description

The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :

- Multiple remote code execution vulnerabilities exist due to improper validation of vSMB packets. An attacker on a guest operating system can exploit these vulnerabilities, via a specially crafted application, to execute arbitrary code on the host. (CVE-2017-0021, CVE-2017-0095)

- Multiple denial of service vulnerabilities exist due to improper validation of input from a privileged user on a guest operating system. An attacker with a privileged account on a guest operating system can exploit these vulnerabilities, via a specially crafted application, to crash the host machine. (CVE-2017-0051, CVE-2017-0074, CVE-2017-0076, CVE-2017-0097, CVE-2017-0098, CVE-2017-0099)

Note that customers who have not enabled the Hyper-V role are not affected.

Solution

Microsoft has released a set of patches for Windows 2008, 7, 2008 R2, 2012, 8.1, 2012 R2, 10 and 2016.

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 smb_nt_ms17-008.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a smb_nt_ms17-008.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - smb_nt_ms17-008.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 smb_nt_ms17-008.nasl -t <IP/HOST>

Go back to menu.
