CVE-2021-38862
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 Data Risk Manager (iDNA) 2.0.6 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 207980.
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 Data Risk Manager (iDNA) version 2.0.6 implements cryptographic algorithms that are weaker than current industry standards, potentially allowing an attacker to decrypt highly sensitive data stored or transmitted by the system.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Confirm iDNA versionRun 'ibmdrctl --version' or check the product UI under About/Help section to identify the exact installed version of IBM Data Risk ManagerAffected if The installed version is exactly 2.0.6
-
Locate cryptographic configuration filesSearch for configuration files in the iDNA installation directory (typically under /opt/ibm or the product's config folder) related to encryption, cryptography, or security settingsAffected if Weak or legacy cryptographic algorithms are configured in the product's security configuration files
-
Inspect SSL/TLS settingsReview SSL/TLS configuration files and settings within iDNA for the cipher suites and protocols in useAffected if The system uses outdated ciphers (such as TLS 1.0/1.1, weak hash algorithms, or short key lengths)
-
Check encryption for data at restExamine database or file storage configurations where iDNA stores sensitive data to identify the encryption method appliedAffected if Data at rest is protected with legacy or weak encryption algorithms
-
Review key management configurationInspect key management settings, key storage locations, and the algorithms used for key derivation or encryption within iDNAAffected if Key management utilizes weak key lengths or deprecated algorithms
The environment is affected if IBM Data Risk Manager version 2.0.6 is installed AND weak cryptographic algorithms are found in the product's configuration for data storage, transmission, or key management.

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 dataReplace weak cryptographic algorithms with modern, industry-standard algorithms (e.g., AES-256, SHA-256) and ensure proper key management. If available, apply IBM security patches for iDNA 2.0.6.
