CVE-2020-4254
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 Security Guardium Big Data Intelligence 1.0 (SonarG) uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 175560.

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 the installed IBM Security Guardium Big Data Intelligence versionCheck the product version through the system management interface or run 'rpm -q guardium-big-data-intelligence' or 'lsb_release -a' if installed on Linux, or check the About section in the web UIAffected if The installed version is exactly 1.0 (all patch levels)
-
Confirm the product is the SonarG variantVerify the product name in the installation directory or system inventory lists 'IBM Security Guardium Big Data Intelligence' or 'SonarG'Affected if The product is IBM Security Guardium Big Data Intelligence version 1.0 (SonarG)
-
Locate encryption configuration filesSearch for configuration files in the installation directory that handle encryption settings, typically in conf/ or config/ subdirectoriesAffected if Weak or deprecated cryptographic algorithms (such as MD5, SHA1, DES, or similar) are configured or in use
-
Inspect cryptographic algorithm settingsExamine encryption-related configuration files or settings panels for algorithm specificationsAffected if The system is configured to use weak cryptographic algorithms for storing or protecting sensitive data
A user is affected if IBM Security Guardium Big Data Intelligence (SonarG) version 1.0 is installed and the system uses weak cryptographic algorithms for data protection.

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 dataApply IBM's security patch for CVE-2020-4254 or upgrade to a patched version of Guardium Big Data Intelligence. If immediate patching is not possible, implement compensating controls such as additional encryption layers or network segmentation to protect sensitive data.
