CVE-2024-7387: OpenShift Builder has a path traversal, allows command injection in privileged BuildContainer

A flaw was found in openshift/builder. This vulnerability allows command injection via path traversal, where a malicious user can execute arbitrary commands on the OpenShift node running the builder container. When using the "Docker" strategy, executable files inside the privileged build container can be overridden using the spec.source.secrets.secret.destinationDir attribute of the BuildConfig definition. An attacker running code in a privileged container could escalate their permissions on the node running the container.

Root Cause Analysis

The vulnerability stems from the copyLocalObject function's handling of destination paths. Prior to the patch, it:

Constructed dstDir via filepath.Join(targetDir, s.DestinationPath()) without validating if the resolved path remained under targetDir.
Failed to resolve symlinks in dstDir before checking path containment.
Used 'cp -LRf' which followed symlinks, allowing overwriting of critical binaries in privileged containers. The commit 0b62633adfa28 explicitly added symlink resolution and HasPrefix checks to fix this, confirming copyLocalObject was the vulnerable component.
