Red Hat Security Advisory 2023-2014-01 - 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 container images for Red Hat OpenShift Container Platform 4.11.39. Issues addressed include a denial of service vulnerability.

Red Hat Security Advisory 2023-2061-01 - Multicluster Engine for Kubernetes 2.1.6 images Multicluster engine for Kubernetes provides the foundational components that are necessary for the centralized management of multiple Kubernetes-based clusters across data centers, public clouds, and private clouds. You can use the engine to create new Red Hat OpenShift Container Platform clusters or to bring existing Kubernetes-based clusters under management by importing them. After the clusters are managed, you can use the APIs that are provided by the engine to distribute configuration based on placement policy. Issues addressed include a denial of service vulnerability.

** UNSUPPORTED WHEN ASSIGNED ** The Apache Spark UI offers the possibility to enable ACLs via the configuration option spark.acls.enable. With an authentication filter, this checks whether a user has access permissions to view or modify the application. If ACLs are enabled, a code path in HttpSecurityFilter can allow someone to perform impersonation by providing an arbitrary user name. A malicious user might then be able to reach a permission check function that will ultimately build a Unix shell command based on their input, and execute it. This will result in arbitrary shell command execution as the user Spark is currently running as. This issue was disclosed earlier as CVE-2022-33891, but incorrectly claimed version 3.1.3 (which has since gone EOL) would not be affected. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. Users are recommended to upgrade to a supported version of Apache Spark, such as version 3.4.0.

### Impact Steps to reproduce: Open <xwiki-host>/xwiki/bin/view/XWiki/Notifications/Code/LegacyNotificationAdministration?since=%7B%7B%2Fhtml%7D%7D+%7B%7Basync+async%3D%22true%22+cached%3D%22false%22+context%3D%22doc.reference%22%7D%7D%7B%7Bgroovy%7D%7Dprintln%28%22Hello+%22+%2B+%22from+groovy%21%22%29%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D, where <xwiki-host> is the URL of your XWiki installation. This demonstrates an XWiki syntax injection attack via the since-parameter, allowing privilege escalation from view to programming rights. ### Patches The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8 and 14.10.3. ### Workarounds For versions >= 14.6-rc-1 the workaround is to modify the page `XWiki.Notifications.Code.LegacyNotificationAdministration` to add the missing escaping, as described on https://github.com/xwiki/xwiki-platform/commit/8e7c7f90f2ddaf067cb5b83b181af41513028754#diff-4e13f4ee4a42938bf1201b7ee71ca32edeacba22559daf0bcb89d534e0225949R70 For vers...

### Impact Steps to reproduce: 1. As a user without script or programming right, edit your user profile (or any other document) with the wiki editor and add the content `{{groovy}}println("Hello " + "from Groovy!"){{/groovy}}` 1. Edit the document with the object editor and add an object of type AppWithinMinutes.LiveTableClass (no values need to be set, just save) 1. View the document ### Patches The vulnerability has been patched in XWiki 15.0-rc-1 and 14.10.3. ### Workarounds There is no known workaround. ### References https://jira.xwiki.org/browse/XWIKI-20423 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) * Email us at [Security Mailing List](mailto:[email protected])
