XML external entity (XXE) vulnerability in CloudBees Jenkins before 1.600 and LTS before 1.596.1 allows remote attackers to read arbitrary XML files via a crafted XML document.

The remote Red Hat Enterprise Linux CoreOS 2 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:1844 advisory.

  - jenkins: Combination filter Groovy script unsecured (SECURITY-125) (CVE-2015-1806)

  - jenkins: directory traversal from artifacts via symlink (SECURITY-162) (CVE-2015-1807)

  - jenkins: update center metadata retrieval DoS attack (SECURITY-163) (CVE-2015-1808)

  - jenkins: external entity injection via XPath (SECURITY-165) (CVE-2015-1809)

  - jenkins: HudsonPrivateSecurityRealm allows creation of reserved names (SECURITY-166) (CVE-2015-1810)

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

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - XML external entity (XXE) vulnerability in CloudBees Jenkins before 1.600 and LTS before 1.596.1 allows
    remote attackers to read arbitrary XML files via a crafted XML document. (CVE-2015-1811)

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:1844 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.

    Space precludes documenting all of the bug fixes in this advisory.
    See the OpenShift Enterprise Technical Notes, which will be updated     shortly for release 2.2.7, for details about these changes. The     following security issues are addressed in this release:

    A flaw was found in the Jenkins API token-issuing service. The     service was not properly protected against anonymous users,     potentially allowing remote attackers to escalate privileges.
    (CVE-2015-1814)

    It was found that the combination filter Groovy script could allow     a remote attacker to potentially execute arbitrary code on a     Jenkins master. (CVE-2015-1806)

    It was found that when building artifacts, the Jenkins server would     follow symbolic links, potentially resulting in disclosure of     information on the server. (CVE-2015-1807)

    A denial of service flaw was found in the way Jenkins handled     certain update center data. An authenticated user could provide     specially crafted update center data to Jenkins, causing plug-in     and tool installation to not work properly. (CVE-2015-1808)

    It was found that Jenkins' XPath handling allowed XML External     Entity (XXE) expansion. A remote attacker with read access could     use this flaw to read arbitrary XML files on the Jenkins server.
    (CVE-2015-1809)

    It was discovered that the internal Jenkins user database did not     restrict access to reserved names, allowing users to escalate     privileges. (CVE-2015-1810)

    It was found that Jenkins' XML handling allowed XML External Entity     (XXE) expansion. A remote attacker with the ability to pass XML     data to Jenkins could use this flaw to read arbitrary XML files on     the Jenkins server. (CVE-2015-1811)

    Two cross-site scripting (XSS) flaws were found in Jenkins. A     remote  attacker could use these flaws to conduct XSS attacks     against users of an application using Jenkins. (CVE-2015-1812,     CVE-2015-1813)

    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.
