Red Hat Container Images Privilege Escalation

Container privilege escalation in Red Hat Multicluster Engine for Kubernetes allows authenticated local attackers to escalate from non-root container execution to full root privileges by exploiting group-writable permissions on the /etc/passwd file created during container image build time, enabling arbitrary UID assignment including UID 0.

Container privilege escalation in Red Hat Web Terminal allows local attackers with group membership to modify the /etc/passwd file and create arbitrary user accounts including root. The vulnerability stems from overly permissive group-writable permissions on /etc/passwd during image build, enabling privilege escalation from non-root container users to full root access within the container. Red Hat Web Terminal across multiple versions is affected; no public exploit code or active exploitation has been reported at the time of analysis.

Privilege escalation in OpenShift Update Service (OSUS) container images allows local attackers with high privileges to gain root access by modifying the group-writable /etc/passwd file created during build time. An attacker executing commands within an affected container can leverage root group membership to inject a new user with UID 0, achieving full container root privileges. No public exploit code or active exploitation has been identified at the time of analysis.

Red Hat Process Automation Manager container images allow local privilege escalation when the /etc/passwd file is created with group-writable permissions during the build process. An attacker with non-root command execution capability who is a member of the root group can modify /etc/passwd to create a new user with UID 0, gaining full root privileges within the container. This requires high privileges (membership in root group) and challenging conditions (AC:H), but affects all versions of Red Hat Process Automation 7 distributed as container images. No public exploit code has been identified at the time of analysis.

Container privilege escalation in Red Hat Ansible Automation Platform 2 allows non-root users within affected container images to gain root privileges by modifying the group-writable /etc/passwd file. During the container build process, /etc/passwd is created with overly permissive group-write permissions, enabling any user in the root group to add arbitrary entries including a UID 0 account. This vulnerability requires local container execution access and elevated group membership, but results in complete container compromise when exploited.
