Synopsis

The remote Windows host contains a programming platform that is affected by multiple vulnerabilities.

Description

The version of Oracle (formerly Sun) Java SE or Java for Business installed on the remote host is prior to 10 Update 1, 8 Update 171, 7 Update 181, or 6 Update 191. It is, therefore, affected by multiple vulnerabilities related to the following components :

- AWT - Concurrency - Hotspot - Install - JAXP - JMX - Libraries - RMI - Security - Serialization

Solution

Upgrade to Oracle JDK / JRE 10 Update 1, 8 Update 171 / 7 Update 181 / 6 Update 191 or later. If necessary, remove any affected versions.

Note that an Extended Support contract with Oracle is needed to obtain JDK / JRE 6 Update 95 or later.

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 oracle_java_cpu_apr_2018.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a oracle_java_cpu_apr_2018.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - oracle_java_cpu_apr_2018.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 oracle_java_cpu_apr_2018.nasl -t <IP/HOST>

Go back to menu.
