CVE-2024-45496

Summary

A flaw was found in OpenShift. This issue occurs due to the misuse of elevated privileges in the OpenShift Container Platform's build process. During the build initialization step, the git-clone container is run with a privileged security context, allowing unrestricted access to the node. An attacker with developer-level access can provide a crafted .gitconfig file containing commands executed during the cloning process, leading to arbitrary command execution on the worker node. An attacker running code in a privileged container could escalate their permissions on the node running the container.

Weaknesses

  • CWE-269: Improper Privilege Management

Workarounds

Cluster admins can follow the instructions in "Securing Builds by Strategy" to block use of the "Docker" and “Source” build strategies on a cluster, or restrict the use to a set of highly trusted users, until the cluster is able to be upgraded.
