What is CVE-2025-58712?
CVE-2025-58712 is a medium-severity vulnerability in Red Hat RHEL-9 based Middleware Containers, published on 22 Oct 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
A container privilege escalation flaw was found in certain AMQ Broker 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.
