Vulnerability Information

Severity: Critical
Vulnerability Published: 2019-03-07
Patch Published: 2019-03-07
CVE [?]: CVE-2019-0192
CPE [?]: cpe:/a:apache:solr

Synopsis

The remote web server contains a Java application that is affected by a remote code execution vulnerability.

Description

The version of Apache Solr running on the remote web server is affected by a remote code execution vulnerability in the Config API due to unsafe deserialization of Java objects. An unauthenticated, remote attacker can exploit this, via an HTTP POST request that points the JMX server to a malicious RMI server. An attacker could then send a crafted serialized Java object to the server, to execute arbitrary code.

Solution

Upgrade to Apache Solr version 7.0 or later, refer to the vendor advisory for relevant patch and configuration settings.

How to Run

Here is how to run the Apache Solr 5.x <= 5.5.5 or 6.x <= 6.6.5 Deserialization Vulnerability 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 CGI abuses plugin family.
On the right side table select Apache Solr 5.x <= 5.5.5 or 6.x <= 6.6.5 Deserialization Vulnerability plugin ID 123417.
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 solr_7_0_0.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a solr_7_0_0.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - solr_7_0_0.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 solr_7_0_0.nasl -t <IP/HOST>
