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 Sterling B2B Integrator Standard Edition 6.0.0.0 through 6.0.3.5 and 6.1.0.0 through 6.1.1.0 could allow a remote attacker to obtain sensitive information when a detailed technical error message is returned in the browser. This information could be used in further attacks against the system. IBM X-Force ID: 213963.

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 Sterling B2B Integrator returns detailed technical error messages (potentially including stack traces, file paths, or internal system details) directly in browser responses. This information disclosure could aid attackers in understanding the system's architecture and identifying further attack vectors.

MitigationConfigure the application to use custom error pages that return generic messages without exposing technical details. Review exception handling code to ensure sensitive information is not included in error responses.

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 Sterling B2B Integrator version
    Locate the version file or check the product about page in the admin console. Common paths include the installation directory or check the build number displayed in the system information page.
    Affected if The installed version is 6.0.0.0 through 6.0.3.5, or 6.1.0.0 through 6.1.1.0 (versions falling within >=6.0.0.0,<6.0.3.6 or >=6.1.0.0,<6.1.1.1)
  2. Verify if custom error page handling is configured
    Review the application server configuration files (such as web.xml or equivalent) to determine if custom error pages that return generic messages are configured for error codes like 404, 500, and exception types.
    Affected if Custom error pages are not configured and the default server error pages are in use, which would return detailed stack traces and technical information
  3. Trigger a test error condition to inspect response
    Send a deliberately malformed request or access a non-existent resource within the IBM Sterling B2B Integrator application to generate an error response, then capture and inspect the HTTP response body.
    Affected if The response contains stack traces, file paths, internal class names, or database connection details instead of a generic error message

A user is affected if their IBM Sterling B2B Integrator version falls within 6.0.0.0-6.0.3.5 or 6.1.0.0-6.1.1.0 AND the application returns detailed technical error information in HTTP responses.

Interim mitigation

Configure the application to use custom error pages that return generic messages without exposing technical details. Review exception handling code to ensure sensitive information is not included in error responses.

Recommended fix High confidence

IBM Sterling B2B Integrator 6.0.3.6 or later for 6.0.x branch; 6.1.1.1 or later for 6.1.x branch

  1. 1. Identify the currently installed IBM Sterling B2B Integrator version by checking the system information or release notes.
  2. 2. Plan the upgrade based on your current version branch: If running 6.0.x, upgrade to 6.0.3.6 or later; if running 6.1.x, upgrade to 6.1.1.1 or later.
  3. 3. Review IBM's official upgrade documentation and release notes for the target version to understand prerequisites and procedures.
  4. 4. Perform a full backup of the current system configuration, databases, and any custom configurations before proceeding.
  5. 5. Test the upgrade in a non-production environment first to verify compatibility with existing integrations and custom configurations.
  6. 6. Schedule a maintenance window and apply the upgrade during low-usage period.
  7. 7. After upgrade, verify that the detailed error messages are no longer exposed by testing various error conditions.
  8. 8. Confirm the upgraded version matches the expected fixed version (6.0.3.6+ or 6.1.1.1+).
Caveat Review release notes for any breaking changes between your current version and the target version; custom configurations or integrations may require testing
