GHSA-887V-3W44-3XRW

Vulnerability from github – Published: 2025-12-02 21:31 – Updated: 2025-12-02 21:31

Details

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.

Severity ?

5.2 (Medium)


                  
                    CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:H/A:L
