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 5.2.6.0 through 6.1.1.0 is vulnerable to SQL injection. A remote attacker could send specially crafted SQL statements, which could allow the attacker to view, add, modify or delete information in the back-end database. IBM X-Force ID: 207506.

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
How this class of weakness works · CWE-89

User input is woven into a database query, letting an attacker rewrite the query's logic. From there they can read, alter, or destroy data — frequently the entire database. The reliable fix is parameterised queries (prepared statements), so input is always treated as data and never as SQL.

Recommended fix High confidence

6.1.1.0 or later (IBM Sterling B2B Integrator)

  1. 1. Review the IBM support page at https://www.ibm.com/support/pages/node/6495919 for the specific patch/patch bundle applicable to your current version.
  2. 2. Identify your current IBM Sterling B2B Integrator version by navigating to the Administration > System > Health > About section in the UI.
  3. 3. Based on your current version, plan the upgrade path: For versions 5.2.6.0 through 6.0.3.4, upgrade to version 6.1.1.0 or later. For versions 6.1.0.0 through 6.1.0.3, upgrade to version 6.1.1.0 or later.
  4. 4. Before upgrading, perform a full backup of the database and file system, and document all custom configurations.
  5. 5. Download the appropriate IBM Sterling B2B Integrator installation package for version 6.1.1.0 or the latest stable version from IBM Fix Central.
  6. 6. Execute the upgrade following the IBM-provided installation and migration instructions in the product documentation.
  7. 7. After upgrade, verify the SQL injection vulnerability is resolved by confirming the patch level via the Administration interface.
  8. 8. Test critical business workflows to ensure the upgrade did not disrupt existing integrations.
Caveat Review IBM release notes for version 6.1.1.0 for any changes to functionality, database schema modifications, or migration requirements that may affect existing integrations
