Summary

A container privilege escalation flaw was found in certain CodeReady Workspaces images. This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container.

Risk Assessment

An attacker with command execution in the container can gain root privileges, potentially leading to full control over the container and potentially the host.

Recommendation

Update CodeReady Workspaces images to versions containing the fix. Verify /etc/passwd permissions and restrict command execution in containers.
