Lifecycle Timeline
3Description
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.

Technical Context
Privilege escalation allows a low-privileged user or process to gain elevated permissions beyond what was originally authorized. This vulnerability is classified as Incorrect Default Permissions (CWE-276).
Affected Products
Affected: CodeReady Workspaces images
Remediation
Apply the principle of least privilege. Keep systems patched. Monitor for suspicious privilege changes. Use mandatory access controls (SELinux, AppArmor).
