In Jenkins Script Security Plugin version 1.36 and earlier, users with the ability to configure sandboxed Groovy scripts are able to use a type coercion feature in Groovy to create new `File` objects from strings. This allowed reading arbitrary files on the Jenkins master file system. Such a type coercion is now subject to sandbox protection and considered to be a call to the `new File(String)` constructor for the purpose of in-process script approval. En las versiones 1.36 y anteriores del plugin Script Security de Jenkins, los usuarios que pueden configurar scripts Groovy en sandbox pueden utilizar una característica de coerción de tipos en Groovy para crear nuevos objetos "File" a partir de las cadenas. Esto permitía leer archivos arbitrarios en el sistema de archivos maestro de Jenkins. • https://jenkins.io/security/advisory/2017-12-11 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

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). La lista blanca por defecto incluye las siguientes entradas no seguras: DefaultGroovyMethods.putAt(Object, String, Object); DefaultGroovyMethods.getAt(Object, String). Esto permite omitir muchas de las restricciones de acceso implementadas en el sandbox del script utilizando, por ejemplo, currentBuild['rawBuild'] en vez de currentBuild.rawBuild. • https://jenkins.io/security/advisory/2017-07-10 • CWE-732: Incorrect Permission Assignment for Critical Resource •
