Synopsis

The remote Oracle WebLogic server is affected by a remote code execution vulnerability.

Description

The remote Oracle WebLogic server is affected by a remote code execution vulnerability in the WLS Security component due to unsafe deserialize calls of unauthenticated Java objects to the Apache Commons Collections (ACC) library. An unauthenticated, remote attacker can exploit this to execute arbitrary Java code in the context of the WebLogic server.

Solution

Upgrade to the relevant fixed version referenced in the vendor advisory.

How to Run

Here is how to run the Oracle WebLogic Java Object Deserialization RCE 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 Web Servers plugin family.
On the right side table select Oracle WebLogic Java Object Deserialization RCE plugin ID 87011.
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 weblogic_2015_4852.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a weblogic_2015_4852.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - weblogic_2015_4852.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 weblogic_2015_4852.nasl -t <IP/HOST>

Go back to menu.
