CVE-2017-1000095 Information

Description

The default whitelist included the following unsafe entries: DefaultGroovyMethods.putAt(Object String Object); DefaultGroovyMethods.getAt(Object String). These allowed circumventing many of the access restrictions implemented in the script sandbox by using e.g. currentBuild[‘rawBuild’] rather than currentBuild.rawBuild. Additionally the following entries allowed accessing private data that would not be accessible otherwise due to script security: groovy.json.JsonOutput.toJson(Closure); groovy.json.JsonOutput.toJson(Object).
