Red Hat OpenShift Container Platform release 4.9.35 is now available with updates to packages and images that fix several bugs and add enhancements. This release includes a security update for Red Hat OpenShift Container Platform 4.9. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).

### Impact If an attacker is able to perform a container escape of a container running as root on a host where Cilium is installed, the attacker can leverage Cilium's Kubernetes service account to gain access to cluster privileges that are more permissive than what is minimally required to operate Cilium. In affected releases, this service account had access to modify and delete `Pod` and `Node` resources. ### Patches The problem has been fixed and is available on versions >=1.9.16, >=1.10.11, >=1.11.5 ### Workarounds There are no workarounds available. ### Acknowledgements The Cilium community has worked together with members of Isovalent, Amazon and Palo Alto Networks to prepare these mitigations. Special thanks to Micah Hausler, Robert Clark, Yuval Avrahami, and Shaul Ben Hai for their cooperation. ### For more information If you have any questions or comments about this advisory: Email us at [[email protected]](mailto:[email protected])

### Impact Users with host file system access on a node and the privileges to run as group ID 1000 can gain access to the per node API of Cilium via Unix domain socket on the host where Cilium is running. If a malicious user is able to gain unprivileged access to a user corresponding to this group, then they can leverage this access to compromise the integrity as well as system availability on that host. Operating Systems that have unprivileged users **not** belonging the group ID 1000 are **not** affected by this vulnerability. Best practices for managing the secure deployment of Kubernetes clusters will typically limit the ability for a malicious user to deploy pods with access to this group or to access the host filesystem, and limit user access to the nodes for users belonging to this group. These best practices include (but are not limited to) enforcing Admission Control policies to limit the configuration of Kubernetes Pod [hostPath](https://kubernetes.io/docs/concepts/storage/...

Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. * The attacker creates a workflow that produces a HTML artifact that contains a HTML file that contains a script which uses XHR calls to interact with the Argo Server API. * The attacker emails the deep-link to the artifact to their victim. The victim opens the link, the script starts running. As the script has access to the Argo Server API (as the victim), so may do the following (if the victim may): * Read information about the victim’s workflows. * Create or delete workflows. Notes: * The attacker must be an insider: they must have access to the same cluster as the victim and must already be able to run their own workflows. * The attacker must have an understanding of the victim’s system. They won’t be able to repeatedly probe due to the social engineering aspect. * The attacker is likely leave an audit trail. We have seen no evidence of this in the wild. While th...

Containers revolutionized the development process, acting as a cornerstone for DevOps initiatives, but containers bring complex security risks that are not always obvious. Organizations that don’t mitigate these risks are vulnerable to attack.  In this article, we outline how containers contributed to agile development, which unique security risks containers bring into the picture – and what

Cilium is open source software for providing and securing network connectivity and loadbalancing between application workloads. Prior to versions 1.9.16, 1.10.11, and 1.11.15, if an attacker is able to perform a container escape of a container running as root on a host where Cilium is installed, the attacker can escalate privileges to cluster admin by using Cilium's Kubernetes service account. The problem has been fixed and the patch is available in versions 1.9.16, 1.10.11, and 1.11.5. There are no known workarounds available.

GoCD is a continuous delivery server. GoCD versions 19.11.0 through 21.4.0 (inclusive) are vulnerable to a Document Object Model (DOM)-based cross-site scripting attack via a pipeline run's Stage Details > Graphs tab. It is possible for a malicious script on a attacker-hosted site to execute script that will run within the user's browser context and GoCD session via abuse of a messaging channel used for communication between with the parent page and the stage details graph's iframe. This could allow an attacker to steal a GoCD user's session cookies and/or execute malicious code in the user's context. This issue is fixed in GoCD 22.1.0. There are currently no known workarounds.
