CVE-2018-1223
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 Container Runtime (kubo-release), versions prior to 0.14.0, may leak UAA and vCenter credentials to application logs. A malicious user with the ability to read the application logs could use these credentials to escalate privileges.
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 confidenceCloud Foundry Container Runtime (kubo-release) versions prior to 0.14.0 contain a credential leakage vulnerability where UAA and vCenter credentials are inadvertently written to application logs. An attacker with log read access can obtain these credentials and escalate privileges.

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 kubo-release versionLocate and inspect the kubo-release version using your deployment tooling or package management system (e.g., bosh deployments, Ops Manager, or the release manifest file).Affected if The installed version is any release prior to 0.14.0 (e.g., 0.13.x, 0.12.x, etc.).
-
Locate application log directoriesIdentify where application logs are stored in your Cloud Foundry Container Runtime environment. This is typically configured in your deployment manifest or loggregator settings.Affected if Logs are accessible without proper access controls or are stored in a location readable by unauthorized users.
-
Search logs for UAA credential patternsGrep or search through recent application log files for patterns matching UAA client credentials or tokens. Look for strings containing 'uaa', 'client-secret', 'uaa-client', or similar authentication tokens.Affected if Logs contain plaintext or base64-encoded UAA credentials, client secrets, or authentication tokens.
-
Search logs for vCenter credential patternsGrep or search through recent application log files for patterns matching vCenter credentials. Look for strings containing 'vcenter', 'vsphere', 'vim', or credential-like base64 strings associated with virtualization access.Affected if Logs contain plaintext or base64-encoded vCenter credentials, usernames, or session tokens.
You are affected if kubo-release version is below 0.14.0 AND application logs contain exposed UAA or vCenter credentials that are readable by unauthorized 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 data0.14.0
Upgrade kubo-release to version 0.14.0 or later. Additionally, rotate any exposed UAA and vCenter credentials and review log access controls to limit who can read application logs.
