Description Andrej Nemec 2017-02-02 09:39:29 EST

The following flaw was found in Jenkins:

Secrets such as passwords are typically stored on disk and sent to users as part of some pages in encrypted form. These were encrypted using AES-128 ECB without IV, which exposes Jenkins and the stored secrets to unnecessary risks. Jenkins now encrypts secrets using AES-128 CBC with random IV.
