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.

| type | remote |
Metasploit
| description | This module exploits a vulnerability in Jenkins dynamic routing to bypass the Overall/Read ACL and leverage Groovy metaprogramming to download and execute a malicious JAR file. When the "Java Dropper" target is selected, the original entry point based on classLoader.parseClass is used, which requires the use of Groovy metaprogramming to achieve RCE. When the "Unix In-Memory" target is selected, a newer, higher-level, and more universal entry point based on GroovyShell.parse is used. This permits the use of in-memory arbitrary command execution. The ACL bypass gadget is specific to Jenkins <= 2.137 and will not work on later versions of Jenkins. Tested against Jenkins 2.137 and Pipeline: Groovy Plugin 2.61. |

| 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.
