Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
CloudForms Management Engine (cfme) before 5.7.3 and 5.8.x before 5.8.1 lacks RBAC controls on certain methods in the rails application portion of CloudForms. An attacker with access could use a variety of methods within the rails application portion of CloudForms to escalate privileges.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

CloudForms Management Engine before versions 5.7.3 and 5.8.1 lacks Role-Based Access Control (RBAC) enforcement on certain Rails application methods. An authenticated attacker with baseline access can invoke these unprotected methods to elevate their privileges within the application.

MitigationUpgrade CloudForms Management Engine to version 5.7.3 or later, or 5.8.1 or later, to apply the RBAC controls.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the CloudForms Management Engine version
    Log into the CloudForms appliance via SSH and run: `cat /var/www/miq/vmdb/VERSION` or check the about page in the web UI under the help menu
    Affected if The version displayed is 4.2, 4.6, or is earlier than 5.7.3, or is 5.8.0 (any version before 5.7.3 or 5.8.1 within the 5.8.x line)
  2. Confirm the Red Hat CloudForms product version
    Check the appliance product version with: `cat /etc/redhat-release` or look at the product name displayed at login
    Affected if The product reports as CloudForms 4.2 or 4.6 specifically
  3. Verify the Rails application is accessible
    Confirm the CloudForms web UI is reachable at the appliance hostname or IP address on ports 443 or 80
    Affected if The web interface is exposed and accepts authentication requests
  4. Determine if baseline user authentication is enabled
    Check if local or external authentication is configured in CloudForms under Configuration > Authentication
    Affected if Authentication is enabled allowing users to log in with baseline (non-admin) privileges

A user is affected if the installed CloudForms version matches 4.2, 4.6, or any version before 5.7.3, or is version 5.8.0, and the web interface with user authentication is accessible.
