What is CVE-2017-1000505?
CVE-2017-1000505 is a medium-severity path traversal vulnerability in n/a, published on 25 Jan 2018. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-200
