Jenkins Security Advisory 2016-11-16

    Added by Daniel Beck, last edited by Daniel Beck on Nov 16, 2016

This advisory announces the fix for a previously disclosed zero-day 
vulnerability in Jenkins.


Remote code execution vulnerability in remoting module

SECURITY-360 / CVE-2016-9299

An unauthenticated remote code execution vulnerability allowed attackers to 
transfer a serialized Java object to the Jenkins CLI, making Jenkins connect 
to an attacker-controlled LDAP server, which in turn can send a serialized 
payload leading to code execution, bypassing existing protection mechanisms.


    SECURITY-360 is considered critical as it allows unprivileged attackers to
execute arbitrary code.

Affected versions

    All Jenkins main line releases up to and including 2.31

    All Jenkins LTS releases up to and including 2.19.2


    Jenkins main line users should update to 2.32

    Jenkins LTS users should update to 2.19.3

These versions include fixes to all the vulnerabilities described above. All 
prior versions are affected by these vulnerabilities.


As part of this fix, a number of other so-called "gadgets" were reviewed and 
are now also being prohibited. We tracked this activity as SECURITY-317.
