Unsafe Default Whitelist Entries Allowing Access to Private Data and Circumventing Script Security

CVE-2017-1000095 · MEDIUM Severity

AV:N/AC:L/AU:S/C:P/I:N/A:N

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).
