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
IBM API Connect V2018.4.1.0 through 2018.4.1.11 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 181324.

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 confidence

IBM API Connect versions 2018.4.1.0 through 2018.4.1.11 implement weaker than expected cryptographic algorithms, enabling attackers to decrypt highly sensitive information. This cryptographic weakness compromises data confidentiality and requires algorithmic upgrades to stronger standards.

MitigationUpgrade IBM API Connect to a version beyond 2018.4.1.11 that addresses the weak cryptographic algorithms, and re-encrypt any previously encrypted sensitive data using the strengthened algorithms.

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. Identify IBM API Connect version
    Locate the installed IBM API Connect version through the management UI (API Manager > Settings > Version), the command line (apic version or kubectl get pods), or the product information file
    Affected if The installed version is 2018.4.1.0 through 2018.4.1.11 inclusive
  2. Compare version against vulnerable range
    Compare your identified version number against the affected range: 2018.4.1.0 <= version <= 2018.4.1.11
    Affected if Your version falls within or below 2018.4.1.11 (versions 2018.4.1.0 through 2018.4.1.11 are affected)
  3. Identify encrypted sensitive data
    Review stored data assets in your API Connect environment that rely on encryption, such as API secrets, OAuth credentials, TLS certificates, or sensitive payload data
    Affected if Encrypted sensitive data exists in the environment and could be decrypted by an attacker exploiting the weak cryptographic algorithms

You are affected if your IBM API Connect version is 2018.4.1.0 through 2018.4.1.11 and you have sensitive encrypted data stored that could be decrypted by exploiting the weak cryptographic algorithms.

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 data
Upgrade available Upgrade to a release after 2018.4.1.11
Interim mitigation

Upgrade IBM API Connect to a version beyond 2018.4.1.11 that addresses the weak cryptographic algorithms, and re-encrypt any previously encrypted sensitive data using the strengthened algorithms.
