Arbitrary File Read Vulnerability in Jenkins Script Security Plugin

CVE-2017-1000505 · MEDIUM Severity

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

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.
