The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:2517 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 3.11.462. See the following advisory for the container images for this release:
https://access.redhat.com/errata/RHBA-2021:2516
Space precludes documenting all of the bug fixes and enhancements in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes:
https://docs.openshift.com/container-platform/3.11/release_notes/ocp_3_11_release_notes.html
All OpenShift Container Platform 3.11 users are advised to upgrade to these updated packages and images.
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)
* jetty: local temporary directory hijacking vulnerability (CVE-2020-27216)
* jetty: buffer not correctly recycled in Gzip Request inflation (CVE-2020-27218)
* jetty: request containing multiple Accept headers with a large number of quality parameters may lead to DoS (CVE-2020-27223)
* 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.
(CVE-2021-21645)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
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.
