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 Counter Fraud Management for Safer Payments 6.1.0.00 through 6.1.1.02, 6.2.0.00 through 6.2.2.02, 6.3.0.00 through 6.3.1.02, 6.4.0.00 through 6.4.2.01, and 6.5.0.00 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 249192.

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 · high confidence

IBM Counter Fraud Management for Safer Payments uses weaker than expected cryptographic algorithms (such as outdated hash functions or weak ciphers) across multiple version ranges, potentially allowing attackers to decrypt highly sensitive financial fraud data.

MitigationUpgrade to a patched version of IBM Counter Fraud Management for Safer Payments that implements stronger cryptographic algorithms; ensure the system is not exposed to untrusted networks and implement additional encryption layers as a defense-in-depth measure.

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 installed IBM Safer Payments version
    Run the command 'spversion' or check the product information via the Safer Payments admin interface, typically found under Help > About or in the installation directory readme file
    Affected if The installed version falls within any of these ranges: 6.1.0.00 through 6.1.1.02, 6.2.0.00 through 6.2.2.02, 6.3.0.00 through 6.3.1.02, 6.4.0.00 through 6.4.2.01, or is exactly 6.5.0.00
  2. Confirm product is IBM Counter Fraud Management for Safer Payments
    Verify the installed product name matches IBM Safer Payments or IBM Counter Fraud Management for Safer Payments using the version command output or admin console
    Affected if The product is IBM Safer Payments and the version is in the affected ranges listed above
  3. Check for sensitive data encryption configuration
    Review the Safer Payments configuration files (typically in the config directory) for encryption-related settings, or query the system configuration via the admin interface for cryptographic algorithm settings
    Affected if The system uses default encryption settings and the version is in the affected range, as the vulnerability relates to weak default cryptographic algorithms in the product itself

A user is affected if IBM Safer Payments version is 6.1.0.00-6.1.1.02, 6.2.0.00-6.2.2.02, 6.3.0.00-6.3.1.02, 6.4.0.00-6.4.2.01, or exactly 6.5.0.00, as these versions use weaker than expected cryptographic algorithms by default.

Upgrade available Upgrade to 6.1.1.03 / 6.2.2.03 / 6.3.1.03 or later
Fixed in 6.1.1.036.2.2.036.3.1.03
Interim mitigation

Upgrade to a patched version of IBM Counter Fraud Management for Safer Payments that implements stronger cryptographic algorithms; ensure the system is not exposed to untrusted networks and implement additional encryption layers as a defense-in-depth measure.

Recommended fix High confidence

Upgrade to 6.1.1.03 (for 6.1.x), 6.2.2.03 (for 6.2.x), 6.3.1.03 (for 6.3.x), or 6.4.2.02 (for 6.4.x)

  1. 1. Identify the currently installed version of IBM Safer Payments by checking the system documentation or admin console
  2. 2. Determine the appropriate upgrade path based on your current major.minor version (6.1.x, 6.2.x, 6.3.x, or 6.4.x)
  3. 3. Obtain the upgrade package from IBM Fix Central or official IBM support channels
  4. 4. Review IBM's upgrade documentation and release notes for the target version
  5. 5. Perform a complete backup of the Safer Payments system and database
  6. 6. Test the upgrade in a non-production environment first
  7. 7. Apply the upgrade during a planned maintenance window following IBM's official upgrade procedure
  8. 8. Verify the installation and test that Safer Payments functions correctly
Caveat Review release notes for any configuration or behavioral changes between versions; minor version upgrades typically have minimal breaking changes but test thoroughly
