Description Martin Prpič 2015-12-15 15:42:07 UTC 
While the Jenkins update site data is digitally signed, and the signature verified by Jenkins, Jenkins did not verify the provided SHA-1 checksums for the plugin files referenced in the update site data. This enabled MITM attacks on the plugin manager, resulting in installation of attacker-provided plugins.

This could allow attackers able to manipulate the network path between Jenkins and the update site to install and run arbitrary code on Jenkins.
