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 · unedited
The Auto-Scaling agent in Liberty for Java in IBM Bluemix before 2.7-20160321-1358 allows remote authenticated users to disable X.509 certificate validation, and consequently bypass an intended HTTPS trust-management feature, 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 confidence

The Auto-Scaling agent in IBM Bluemix's Liberty for Java contains a flaw that allows any remote authenticated user to disable X.509 certificate validation through unspecified vectors, effectively bypassing the HTTPS trust-management protection that should be enforced.

MitigationUpgrade the Liberty for Java runtime in IBM Bluemix to version 2.7-20160321-1358 or later to obtain the patch for this certificate validation bypass vulnerability.

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. Confirm IBM Bluemix Liberty for Java usage
    Identify if your application is deployed on IBM Bluemix using the Liberty for Java runtime environment
    Affected if Using IBM Bluemix with Liberty for Java runtime
  2. Check Auto-Scaling agent status
    Examine your Bluemix application configuration to determine if the Auto-Scaling agent is enabled
    Affected if Auto-Scaling agent is enabled in your Liberty for Java application
  3. Inspect HTTPS trust configuration
    Review the Liberty for Java server configuration files (server.xml) for any settings related to SSL certificate validation or HTTPS trust management
    Affected if Certificate validation can be disabled or is not enforced for HTTPS connections in the server configuration
  4. Verify SSL/TLS settings in application
    Check application code and configuration for any SSLContext or TrustManager configurations that disable certificate validation
    Affected if Application contains code that disables certificate validation

Your environment is affected if you are using IBM Bluemix Liberty for Java with the Auto-Scaling agent enabled, since the vulnerability allows remote authenticated users to bypass X.509 certificate validation for HTTPS connections
