Description Andrej Nemec 2018-10-25 09:14:48 UTC 
Users with Job/Configure permission could specify a relative path escaping the base directory in the file name portion of a file parameter definition. This path would be used to archive the uploaded file on the Jenkins master, resulting in an arbitrary file write vulnerability.

Jenkins security policy[0]:

"Any security advisory related updates to Jenkins core or the plugins we include in the OpenShift Jenkins master image will only occur in the v3.11 and v4.x branches of this repository.

We do support running the v3.11 version of the master image against older v3.x (as far back as v3.4) OpenShift clusters if you want to pick up Jenkins security advisory updates."
