CVE-2019-1003034 – jenkins-job-dsl-plugin: Script security sandbox bypass in Job DSL Plugin (SECURITY-1342)

https://notcve.org/view.php?id=CVE-2019-1003034

A sandbox bypass vulnerability exists in Jenkins Job DSL Plugin 1.71 and earlier in job-dsl-core/src/main/groovy/javaposse/jobdsl/dsl/AbstractDslScriptLoader.groovy, job-dsl-plugin/build.gradle, job-dsl-plugin/src/main/groovy/javaposse/jobdsl/plugin/JobDslWhitelist.groovy, job-dsl-plugin/src/main/groovy/javaposse/jobdsl/plugin/SandboxDslScriptLoader.groovy that allows attackers with control over Job DSL definitions to execute arbitrary code on the Jenkins master JVM. Existe una vulnerabilidad de omisión de sandbox en el plugin Jenkins Job DSL, en versiones 1.71 y anteriores, en job-dsl-core/src/main/groovy/javaposse/jobdsl/dsl/AbstractDslScriptLoader.groovy, job-dsl-plugin/build.gradle, job-dsl-plugin/src/main/groovy/javaposse/jobdsl/plugin/JobDslWhitelist.groovy y job-dsl-plugin/src/main/groovy/javaposse/jobdsl/plugin/SandboxDslScriptLoader.groovy que permite a los atacantes con control sobre las definiciones DSL "Job" ejecutar código arbitrario en el maestro JVM de Jenkins. A flaw was found in the Jenkins Job DSL plugin. Parsing, compilation, and script instantiations provided by a crafted Groovy script could escape the sandbox allowing users to execute arbitrary code on the Jenkins master. The highest risk from this vulnerability is to data confidentiality and integrity as well as system availability. • http://www.securityfocus.com/bid/107476 https://access.redhat.com/errata/RHSA-2019:0739 https://jenkins.io/security/advisory/2019-03-06/#SECURITY-1342 https://access.redhat.com/security/cve/CVE-2019-1003034 https://bugzilla.redhat.com/show_bug.cgi?id=1690663 • CWE-20: Improper Input Validation •
