CVE-2014-0057
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 · uneditedThe x_button method in the ServiceController (vmdb/app/controllers/service_controller.rb) in Red Hat CloudForms 3.0 Management Engine 5.2 allows remote attackers to execute arbitrary methods 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 · high confidenceThe x_button method in ServiceController of Red Hat CloudForms 3.0 Management Engine 5.2 lacks proper access controls, allowing remote unauthenticated attackers to invoke arbitrary methods on the server. This is a critical authorization bypass vulnerability in the Ruby on Rails application that permits remote code execution or administrative actions without authentication.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed CloudForms versionCheck the product version via the web UI (top-right corner or About page) or by running: rpm -q cfme. If using the ManageIQ downstream, run: rpm -q manageiq-core or check /var/www/miq/vmdb/VERSION fileAffected if Version equals 3.0 for CloudForms or 5.2 for CloudForms Management Engine
-
Verify Ruby on Rails application is exposedDetermine if the CloudForms web interface (typically on ports 443, 8443, or 3000) is accessible over the network. Check for exposed ports: netstat -tlnp | grep -E '(443|8443|3000)' or nmap scan of the hostAffected if The web application port is directly accessible from untrusted networks without VPN or firewall filtering
-
Inspect ServiceController access control configurationLocate the ServiceController source file (typically in /var/www/miq/vmdb/app/controllers/service_controller.rb or similar path depending on installation). Examine the x_button method for before_filter or before_action authentication decoratorsAffected if No before_filter : authenticate_or_filter is present, or the authentication check is missing/disabled for the x_button method
-
Test unauthenticated access to x_button endpointSend a crafted GET or POST request to /service/x_button?button=any_method without providing session credentials. Example using curl: curl -k https://<hostname>/service/x_button?button=diagnosticsAffected if The request executes without returning HTTP 401 or redirecting to a login page, indicating the method can be invoked without authentication
-
Check for method whitelisting in controllerExamine the x_button method implementation to determine if method names are whitelisted or if arbitrary method names are accepted via params[:button] or similar parametersAffected if The controller accepts arbitrary method names from user input without validation, allowing any Rails method to be called
The environment is affected if running CloudForms 3.0 or Management Engine 5.2 with the ServiceController#x_button endpoint exposed and lacking proper authentication checks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patches for CVE-2014-0057 immediately. If patches are unavailable, implement emergency access controls on the ServiceController#x_button method to validate method invocation authorization before processing requests.
