CVE-2017-7530
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 · uneditedIn CloudForms Management Engine (cfme) before 5.7.3 and 5.8.x before 5.8.1, it was found that privilege check is missing when invoking arbitrary methods via filtering on VMs that MiqExpression will execute that is triggerable by API users. An attacker could use this to execute actions they should not be allowed to (e.g. destroying VMs).
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 confidenceThis is an authorization bypass vulnerability in CloudForms Management Engine where the API fails to perform privilege checks before executing arbitrary methods filtered through MiqExpression on VMs. API users can invoke methods they should not have permission to execute, such as destroying VMs.

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 the CloudForms Management Engine versionAccess the appliance administration interface or check the product version in the management console. The version is typically displayed in the UI footer or accessible via the /about endpoint on the appliance.Affected if The installed version is 4.5, or is less than 5.7.3, or is >= 5.8.0 but less than 5.8.1.
-
Confirm the API is enabled and accessibleCheck if the CloudForms API endpoint responds. This is typically available at /api on the CloudForms appliance. Attempt a simple API request to verify the service is running.Affected if The API service is running and accessible to the user in question.
-
Review API access logs for unauthorized method callsExamine the API audit logs or production logs for requests to the /api/vms endpoint that include MiqExpression filtering with destructive methods such as destroy, delete, or terminate.Affected if Logs show API calls invoking destructive methods on VMs through MiqExpression that were not initiated by users with appropriate administrative privileges.
-
Check for unexpected VM deletion eventsReview CloudForms event logs or audit trail for VM destruction events that do not correspond to known, authorized administrative actions. Look for rapid or bulk VM deletions.Affected if There are VM destruction events in logs that cannot be traced to legitimate privileged user actions.
A user is affected if they are running a vulnerable CloudForms version (4.5, <5.7.3, or >=5.8.0 to <5.8.1) with the API accessible, and either detect unauthorized VM operations in logs or the API is exposed to untrusted users.

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 data5.7.35.8.1
Upgrade CloudForms Management Engine to version 5.7.3 or later, or 5.8.1 or later. Until patched, restrict API access to trusted users only and monitor for unauthorized VM destruction events.
