CVE-2019-11283
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 · uneditedCloud Foundry SMB Volume, versions prior to v2.0.3, accidentally outputs sensitive information to the logs. A remote user with access to the SMB Volume logs can discover the username and password for volumes that have been recently created, allowing the user to take control of the SMB Volume.
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 Cloud Foundry SMB Volume service (versions prior to v2.0.3) has a sensitive information disclosure vulnerability where username and password credentials for newly created SMB volumes are inadvertently written to service logs. An attacker with access to these logs can retrieve the credentials and gain unauthorized control over the affected SMB volumes.

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 if SMB Volume service is deployedQuery your Cloud Foundry deployment for the SMB Volume service broker. Run 'cf service-brokers' or check the deployment manifests for smb-volume releases.Affected if SMB Volume service broker is present in the deployment
-
Check SMB Volume service versionExamine the version of the Cloud Foundry SMB Volume release in your deployment. For BOSH deployments, run 'bosh releases' and look for the smb-volume release. Compare the version number against the affected ranges: Cf Deployment < 12.2.0 or Smb Volume < 2.0.3.Affected if The installed version is prior to v2.0.3 for SMB Volume or prior to 12.2.0 for Cf Deployment
-
Determine if any SMB volumes were createdList all service instances of type SMB in your Cloud Foundry environment using 'cf services' or query the service broker database. Check for any active or deleted SMB volume service instances.Affected if Any SMB volume service instances were ever created in the environment
-
Search service logs for exposed credentialsReview logs from the SMB Volume service broker and related components (typically found in the syslog or loggregator output). Search for patterns containing 'smb', 'username', 'password', 'credential', 'smbvol' along with what appear to be authentication strings. Focus on timestamps corresponding to SMB volume creation events.Affected if Logs contain plaintext SMB username or password strings alongside volume creation events
You are affected if the SMB Volume service is deployed with a version prior to v2.0.3 (or Cf Deployment prior to 12.2.0) AND any SMB volumes were ever created, with credentials visible in service logs.

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 data2.0.312.2.0
Upgrade Cloud Foundry SMB Volume to version v2.0.3 or later to eliminate the credential logging. Additionally, rotate any SMB volume credentials that may have been exposed in logs prior to the upgrade, and review log access controls to limit exposure.
