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
The Red Hat CloudForms Management Engine 5.1 allow remote administrators to execute arbitrary Ruby code via unspecified vectors.

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 · moderate confidence

Red Hat CloudForms Management Engine 5.1 contains a vulnerability allowing remote administrators to execute arbitrary Ruby code through unspecified vectors. This represents a critical code injection flaw that could enable complete system compromise by authenticated remote attackers.

MitigationUpgrade to a patched version of CloudForms Management Engine. If upgrading is not immediately feasible, restrict administrative access to trusted networks only and monitor for suspicious Ruby code execution attempts.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 if CloudForms Management Engine is installed
    Check for the presence of CloudForms services or web application. Common methods include: looking for the ManageIQ/CloudForms process (evm_server), checking for /var/www/miq/vmdb directory, or querying system packages with 'rpm -qa | grep -i cloudforms' or 'rpm -qa | grep -i manageiq'
    Affected if CloudForms Management Engine software is present on the system
  2. Determine the installed version
    Run the version check command for your installation method. For RPM-based systems: 'rpm -qa | grep -i cloudforms' or check the evm version via the web interface at /about or via API. Compare the version number to the affected version 5.1
    Affected if The installed version is exactly 5.1
  3. Verify remote administration interface is accessible
    Check if the CloudForms web interface (typically on ports 443, 8443, or 3000) is exposed and accessible from network locations. Review firewall rules and Apache/nginx configuration for the CloudForms virtual appliance
    Affected if The web management console is accessible remotely (not limited to localhost or trusted internal networks)
  4. Check for administrative user access
    Review the CloudForms authentication configuration to confirm remote administrative accounts exist and can authenticate. Check /var/www/miq/vmdb/config/authentication.yml or the database for configured admin users
    Affected if Remote administrative users are configured and can authenticate to the CloudForms interface
  5. Inspect logs for suspicious Ruby execution patterns
    Review CloudForms production logs (typically in /var/www/miq/vmdb/log/production.log) for unusual method calls, eval statements, or unexpected code execution attempts. Search for patterns like 'eval', 'system', 'exec', 'spawn' in unexpected contexts
    Affected if Logs show evidence of arbitrary Ruby code execution that was not initiated by known administrators

A system is affected if CloudForms Management Engine version 5.1 is installed with its remote administrative interface accessible to untrusted networks, allowing authenticated attackers to inject and execute arbitrary Ruby code.
