A sandbox bypass vulnerability exists in Jenkins Script Security Plugin 1.50 and earlier in src/main/java/org/jenkinsci/plugins/scriptsecurity/sandbox/groovy/SecureGroovyScript.java that allows attackers with Overall/Read permission to provide a Groovy script to an HTTP endpoint that can result in arbitrary code execution on the Jenkins master JVM.

  • Monitor HTTP endpoints in Jenkins that accept user-submitted Groovy scripts for the presence of AST transforming annotations such as @Grab in submitted source code, which is the exploitation vector for sandbox bypass during the script compilation phase.
  • Alert on requests to the Jenkins HTTP endpoint used to validate user-submitted Groovy scripts (script validation endpoint) originating from users with only Overall/Read permission, particularly when the submitted payload contains AST transformation annotations.
  • This CVE is an incomplete fix for CVE-2019-1003000 (SECURITY-1266); detections for @Grab and similar AST-transforming annotations in Groovy script submissions should cover both CVEs.
  • ·The vulnerability affects Jenkins Script Security Plugin version 1.50 and earlier only; instances running a patched version (post-1.50) that applies a safe Groovy compiler configuration prohibiting unsafe AST transforming annotations are not affected.
  • ·Red Hat OpenShift Container Platform versions 3.2 through 3.10 are listed as 'Will not fix', meaning patched container images may not be available for those versions; detection and mitigation remain the primary controls.
