CVE-2018-1720
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 Sterling B2B Integrator Standard Edition 5.2.0.1, 5.2.6.3_6, 6.0.0.0, and 6.0.0.1 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 147294.
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 Sterling B2B Integrator versions 5.2.0.1 through 6.0.0.1 implement weaker-than-expected cryptographic algorithms, allowing attackers to decrypt highly sensitive information that should be protected by stronger encryption standards.

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 Sterling B2B Integrator versionAccess the product administration console or run the version command provided in the product documentation. Check the 'About' or 'System Information' section in the UI, or locate the version file in the installation directory.Affected if The installed version is 5.2.0.1, 5.2.6.3_6, 6.0.0.0, or 6.0.0.1.
-
Locate the cryptographic configuration settingsAccess the product configuration files or security settings panel in the administration interface. Look for sections related to encryption, SSL/TLS, or cryptographic algorithm configuration.Affected if Weak or deprecated cryptographic algorithms (such as weak ciphers or hash functions) are configured or enabled.
-
Inspect SSL/TLS cipher configurationsReview the SSL/TLS configuration files or settings that define which cipher suites are permitted. Check for the presence of weak ciphers such as those with short key lengths or known vulnerabilities.Affected if Weak cipher suites are enabled or strong ciphers are not required for secure communications.
-
Verify encryption settings for sensitive data storageExamine the configuration that governs how sensitive data (such as passwords, keys, or personal information) is encrypted at rest. Look for settings that specify the encryption algorithm used.Affected if The encryption algorithm specified for protecting sensitive data is considered weak by current standards.
-
Check for default or hardcoded cryptographic keysReview the security configuration to determine if default cryptographic keys or weak key generation methods are in use. Look for any documented weak key configurations.Affected if Default keys or weak key derivation methods are detected in the configuration.
A user is affected if their installed IBM Sterling B2B Integrator version is one of the listed affected versions (5.2.0.1, 5.2.6.3_6, 6.0.0.0, or 6.0.0.1) AND weak cryptographic algorithms are enabled or configured in the system.

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 a patched version of IBM Sterling B2B Integrator that implements stronger cryptographic algorithms, or reconfigure the product to use stronger encryption ciphers and protocols.
