CVE-2019-4399
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 · uneditedIBM Cloud Orchestrator 2.4 through 2.4.0.5 and 2.5 through 2.5.0.9 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 162260.
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 · moderate confidenceIBM Cloud Orchestrator versions 2.4 through 2.4.0.5 and 2.5 through 2.5.0.9 implements weaker than expected cryptographic algorithms, enabling attackers to decrypt highly sensitive information that was intended to be protected.

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.
-
Verify IBM Cloud Orchestrator is installedLocate IBM Cloud Orchestrator installation by checking for its typical installation directories or running commands like 'ls /opt/ibm/cloud*' or querying installed packages via RPM/YUM/DPMI depending on the OSAffected if IBM Cloud Orchestrator software is present on the system
-
Determine installed version of IBM Cloud OrchestratorRun version detection commands such as 'ico version', 'cloudOrchestrator version', or check installation logs, properties files, or the product's About page via its management consoleAffected if The version cannot be determined or returns a version lower than 2.4.0.0 or between 2.4.0.6-2.4.0.9 for the 2.4 branch, or between 2.5.0.10-2.5.0.999 for the 2.5 branch
-
Compare installed version to affected rangesCompare the detected version number against the affected ranges: 2.4.0.0 through 2.4.0.5 inclusive, and 2.5.0.0 through 2.5.0.9 inclusiveAffected if The installed version falls within 2.4.0.0-2.4.0.5 or 2.5.0.0-2.5.0.9, indicating the product uses weaker than expected cryptographic algorithms
If IBM Cloud Orchestrator is installed and its version is between 2.4.0.0-2.4.0.5 or between 2.5.0.0-2.5.0.9, the environment is affected by this weak cryptographic algorithm vulnerability.

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 dataUpgrade to IBM Cloud Orchestrator versions beyond 2.4.0.5 and 2.5.0.9 that implement stronger cryptographic algorithms; also audit existing encrypted data for potential compromise.
