The Jenkins CLI subsystem in Jenkins before 1.638 and LTS before 1.625.2 allows remote attackers to execute arbitrary code via a crafted serialized Java object, related to a problematic webapps/ROOT/WEB-INF/lib/commons-collections-*.jar file and the "Groovy variant in 'ysoserial'".

Red Hat OpenShift Enterprise release 3.1.1 is now available with updates to packages that fix several security issues, bugs and introduce feature enhancements.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

OpenShift Enterprise by Red Hat is the company's cloud computing Platform-as-a-Service (PaaS) solution designed for on-premise or private cloud deployments.

The following security issues are addressed with this release :

An authorization flaw was discovered in Kubernetes; the API server did not properly check user permissions when handling certain requests. An authenticated remote attacker could use this flaw to gain additional access to resources such as RAM and disk space. (CVE-2016-1905)

An authorization flaw was discovered in Kubernetes; the API server did not properly check user permissions when handling certain build- configuration strategies. A remote attacker could create build configurations with strategies that violate policy. Although the attacker could not launch the build themselves (launch fails when the policy is violated), if the build configuration files were later launched by other privileged services (such as automated triggers), user privileges could be bypassed allowing attacker escalation.
(CVE-2016-1906)

An update for Jenkins Continuous Integration Server that addresses a large number of security issues including XSS, CSRF, information disclosure and code execution have been addressed as well.

All OpenShift Enterprise 3 users are advised to upgrade to these updated packages.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:0489 advisory.

    OpenShift Enterprise by Red Hat is the company's cloud computing     Platform-as-a-Service (PaaS) solution designed for on-premise or     private cloud deployments.

    The following security issue is addressed with this release:

    It was found that ActiveMQ did not safely handle user supplied data     when deserializing objects. A remote attacker could use this flaw to     execute arbitrary code with the permissions of the ActiveMQ     application. (CVE-2015-5254)

    An update for Jenkins Continuous Integration Server that addresses a     large number of security issues including XSS, CSRF, information     disclosure and code execution have been addressed as well.
    (CVE-2015-5317, CVE-2015-5318, CVE-2015-5319, CVE-2015-5320,     CVE-2015-5321, CVE-2015-5322, CVE-2015-5323, CVE-2015-5324,     CVE-2015-5325, CVE-2015-5326, CVE-2015-7537, CVE-2015-7538,     CVE-2015-7539, CVE-2015-8103)

    Space precludes documenting all of the bug fixes in this advisory. See     the OpenShift Enterprise Technical Notes, which will be updated     shortly for release 2.2.9, for details about these changes:

    https://access.redhat.com/documentation/en-US/OpenShift_Enterprise/2/html-     single/Technical_Notes/index.html

    All OpenShift Enterprise 2 users are advised to upgrade to these     updated packages.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote web server hosts a version of Jenkins or Jenkins Enterprise that is prior to 1.638 or 1.625.2. It is, therefore, affected by a flaw in the Apache Commons Collections (ACC) library that allows the deserialization of unauthenticated Java objects. An unauthenticated, remote attacker can exploit this to execute arbitrary code on the target host.
