The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:2122 advisory.

    Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution     designed for on-premise or private cloud deployments.

    This advisory contains the RPM packages for Red Hat OpenShift Container Platform 4.7.13. See the following     advisory for the container images for this release:

    https://access.redhat.com/errata/RHSA-2021:2121

    Security Fix(es):

    * jenkins-2-plugins/config-file-provider: Does not configure its XML parser to prevent XML external entity     (XXE) attacks. (CVE-2021-21642)

    * golang: data race in certain net/http servers including ReverseProxy can lead to DoS (CVE-2020-15586)

    * golang: ReadUvarint and ReadVarint can read an unlimited number of bytes from invalid inputs     (CVE-2020-16845)

    * jenkins-2-plugins/config-file-provider: Does not correctly perform permission checks in several HTTP     endpoints. (CVE-2021-21643)

    * jenkins-2-plugins/config-file-provider: does not require POST requests for an HTTP endpoint, resulting     in a cross-site request forgery (CSRF) vulnerability. (CVE-2021-21644)

    * jenkins-2-plugins/config-file-provider: Does not perform permission checks in several HTTP endpoints.

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

The version of Jenkins Enterprise or Jenkins Operations Center running on the remote web server is 2.249.x prior to 2.249.31.0.1-2, or 2.x prior to 2.277.3.1-2. It is, therefore, affected by multiple vulnerabilities, including the following:

  - Jenkins Config File Provider Plugin 3.7.0 and earlier does not configure its XML parser to prevent XML     external entity (XXE) attacks. (CVE-2021-21642)

  - A cross-site request forgery (CSRF) vulnerability in Jenkins Config File Provider Plugin 3.7.0 and earlier     allows attackers to delete configuration files corresponding to an attacker-specified ID. (CVE-2021-21644)

  - Jenkins Templating Engine Plugin 2.1 and earlier does not protect its pipeline configurations using Script     Security Plugin, allowing attackers with Job/Configure permission to execute arbitrary code in the context     of the Jenkins controller JVM. (CVE-2021-21646)

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