Doc Text:
A flaw was found in the Jenkins Script Security plugin through version 1.50. The fix for CVE-2019-1003000 was found to be incomplete. Script Security sandbox protection could be circumvented during the script compilation phase by applying AST transforming annotations such as @Grab to source code elements. This affected an HTTP endpoint used to validate a user-submitted Groovy script that was not covered in the 2019-01-08 fix for SECURITY-1266 and allowed users with Overall/Read permission to bypass the sandbox protection and execute arbitrary code on the Jenkins master. The affected HTTP endpoint now applies a safe Groovy compiler configuration prohibiting unsafe AST transforming annotations. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Description Sam Fowler 2019-01-29 07:24:25 UTC 
Jenkins Script Security plugin through version 1.50 is vulnerable to an incomplete fix to CVE-2019-1003000.

Script Security sandbox protection could be circumvented during the script compilation phase by applying AST transforming annotations such as @Grab to source code elements.

This affected an HTTP endpoint used to validate a user-submitted Groovy script that was not covered in the 2019-01-08 fix for SECURITY-1266 and allowed users with Overall/Read permission to bypass the sandbox protection and execute arbitrary code on the Jenkins master.

The affected HTTP endpoint now applies a safe Groovy compiler configuration prohibiting unsafe AST transforming annotations.
