Who should care

Organizations running IBM Business Automation Workflow in production environments, particularly those with externally accessible interfaces. Security teams responsible for application security and database protection should prioritize review. Compliance teams concerned with data protection regulations may need to assess exposure of database schema information.

Technical summary

The vulnerability exists in IBM Business Automation Workflow's error handling mechanism, where database structure details are included in error messages returned to users. This falls under CWE-209 (Generation of Error Message Containing Sensitive Information). The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) indicates a network-based attack with low attack complexity, requiring low privileges but no user interaction, resulting in low confidentiality impact with no integrity or availability impact. Both containerized and traditional deployment modes are affected.

Defensive priority

Recommended defensive actions

  • Review IBM security bulletin for affected product versions and available patches
  • Configure error handling to suppress detailed database structure information in production environments
  • Apply principle of least privilege to limit access to error-generating endpoints
  • Monitor application logs for unusual error patterns that may indicate probing activity
  • Validate that custom error pages do not expose internal database schema details

Evidence notes

Vendor identification relies on reference domain candidate 'IBM' with low confidence; the official IBM security bulletin confirms IBM as the affected vendor. CVSS vector confirms network attack vector with low privileges required.
