Doc Text:	A flaw was found in the Jenkins Script Security plugin. Sandbox protection could be circumvented through crafted subexpressions used as arguments to method pointer expressions. This allows attackers the ability to specify sandboxed scripts to execute arbitrary code in the context of the Jenkins master JVM. The highest threats from this vulnerability are to data confidentiality and integrity as well as system availability.	Story Points:	---

Description Sam Fowler 2019-08-01 03:25:22 UTC

Sandbox protection in Jenkins Script Security Plugin could be circumvented through crafted subexpressions used as arguments to method pointer expressions. This allowed attackers able to specify sandboxed scripts to execute arbitrary code in the context of the Jenkins master JVM.

Method pointer subexpressions are now subject to sandbox protection.
