Synopsis

A job scheduling and management system hosted on the remote web server is affected by multiple vulnerabilities.

Description

Jenkins running on the remote web server has one or more plugins affected by following vulnerabilities:

- A sandbox bypass vulnerability exists in Script Security Plugin 1.49 and earlier in src/main/java/org/jenkinsci/plugins/scriptsecurity/sandbox/groovy/GroovySandbox.java that allows attackers with the ability to provide sandboxed scripts to execute arbitrary code on the Jenkins master JVM. (CVE-2019-1003000)

- A sandbox bypass vulnerability exists in Pipeline: Groovy Plugin 2.61 and earlier in src/main/java/org/jenkinsci/plugins/workflow/cps/CpsFlowDefinition.java, src/main/java/org/jenkinsci/plugins/workflow/cps/CpsGroovyShellFactory.java that allows attackers with Overall/Read permission to provide a pipeline script to an HTTP endpoint that can result in arbitrary code execution on the Jenkins master JVM. (CVE-2019-1003001)

- A sandbox bypass vulnerability exists in Pipeline: Declarative Plugin 1.3.3 and earlier in pipeline-model-definition/src/main/groovy/org/jenkinsci/plugins/pipeline/modeldefinition/parser/Converter.groovy that allows attackers with Overall/Read permission to provide a pipeline script to an HTTP endpoint that can result in arbitrary code execution on the Jenkins master JVM. (CVE-2019-1003002)

Solution

Refer to vendor advisory for details.

How to Run

Here is how to run the Jenkins Security Advisory 2019-01-08 Multiple Vulnerabilities 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 Jenkins Security Advisory 2019-01-08 Multiple Vulnerabilities plugin ID 129169.
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 jenkins_security_advisory_2019-01-08.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a jenkins_security_advisory_2019-01-08.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - jenkins_security_advisory_2019-01-08.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 jenkins_security_advisory_2019-01-08.nasl -t <IP/HOST>

Go back to menu.
