Description Martin Prpič 2015-11-16 08:58:43 UTC 
The following flaw was found in Jenkins:

JNLP slave connections did not verify that the correct secret was supplied, which allowed malicious users to connect their own machines as slaves to Jenkins knowing only the name of the slave. This enables attackers to take over Jenkins (unless the slave-to-master security subsystem is enabled) or gain access to private data like keys and source code.

This issue allowos for several different attacks, compromising integrity, stability and confidentiality.
