Summary

Red Hat Security Advisory: Red Hat Ansible Automation Platform Execution Environments Update

Severity

Moderate

Notes

Topic: An update is now available for Red Hat Ansible Automation Platform Execution Environments

Details: Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to individual teams, while automation developers retain the freedom to write tasks that leverage existing knowledge without the overhead. Ansible Automation Platform makes it possible for users across an organization to share, vet, and manage automation content by means of a simple, powerful, and agentless language. Update(s) and Fix(es): * Rebuild for base image security fixes

CVE-2025-57847

A container privilege escalation flaw was found in certain Ansible Automation Platform images. This issue arises from the /etc/passwd file being created with group-writable permissions during the build process. 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 vulnerability allows an attacker to add a new user with any arbitrary UID, including UID 0, gaining full root privileges within the container.

This issue arises from the /etc/passwd file being created with group-writable permissions during the build process. 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 vulnerability allows an attacker to add a new user with any arbitrary UID, including UID 0, gaining full root privileges within the container.",

The vulnerability allows for potential privilege escalation within a container, but OpenShift\u0027s default, multi-layered security posture effectively mitigates this risk. \n\nThe primary controls include the default Security Context Constraints (SCC), which severely limit a container\u0027s permissions from the start, and SELinux, which enforces mandatory access control to ensure strict isolation. While other container runtime environments may have different controls available and require case-by-case analysis, OpenShift\u0027s built-in defenses are designed to prevent this type of attack.\n\nOut of Box RHEL configuration isolates a single process inside a container. Unless multiple processes are packaged inside a single container, that defeats the principle behind containerization, this bug can not be used to meaningfully escalate privileges.\n\nAlso, RHEL, and any common linux distributions do NOT add any additional users to the root group. The presence of the root group is strictly due to conformance with POSIX permission management requirements and can be considered to be an artifact of filesystem permission limitations.",
