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 Oracle Cloud Infrastructure Storage Gateway is deployed
    Inventory your cloud infrastructure or on-premises systems to determine if Oracle Cloud Infrastructure Storage Gateway is installed or running. Check your deployment records, container registries, or running services for this specific product.
    Affected if Storage Gateway is present in the environment
  2. Determine the installed version
    Locate the version information for the installed Storage Gateway instance. This may be accessible through the product's admin interface, command-line tools, configuration files, or your deployment documentation.
    Affected if The version is less than 1.4 (for example, 1.3.x, 1.2.x, or earlier)
  3. Verify Management Console accessibility
    Check if the Storage Gateway Management Console is network-accessible via HTTP or HTTPS. Identify the network endpoint or URL used to access the console.
    Affected if The Management Console is exposed to network access
  4. Confirm unauthenticated access is possible
    Test whether the Management Console accepts requests without requiring authentication credentials. Attempt to access console endpoints without providing login credentials.
    Affected if The console allows unauthenticated access

A user is affected if Oracle Cloud Infrastructure Storage Gateway version 1.4 or later is NOT installed AND the Management Console is network-accessible.
