Security readout for executives and security teams
Plain-English summary
This is a low-severity IBM workflow information disclosure issue. In certain nondefault configurations, a logged-in user could see sensitive information about another user. It affects older IBM Business Automation Workflow, Business Process Manager, and listed Cloud Pak for Automation versions.
Executive priority
Handle through normal patch governance unless the affected system contains sensitive identity or workflow data, has many authenticated users, or supports regulated business processes. Escalate if remediation is blocked on exposed or high-value environments.
Technical view
CVE-2021-29751 has CVSS 3.0 score 3.1. The vector indicates network access, low privileges, high attack complexity, no user interaction, unchanged scope, and low confidentiality impact only. The source bundle does not include a CWE or detailed configuration trigger.
Likely exposure
Exposure is most likely where affected IBM workflow products are still deployed, reachable by authenticated users, and configured in the nondefault way referenced by IBM. Internet exposure alone is not enough; an account is required.
Exploitation context
The CVE is not listed as KEV in the provided bundle. The CVSS temporal metric shows exploit code maturity as unproven. No cited source in the bundle supports active exploitation.
Researcher notes
Evidence is limited to IBM and CVE metadata. The bundle confirms affected product families, versions, low confidentiality impact, and nondefault configuration dependency, but not the exact configuration condition or fix package details.
Mitigation direction
- Identify affected IBM product versions in production and support environments.
- Review IBM support advisories for the official fix or upgrade path.
- Prioritize remediation on systems with broad authenticated user access.
- Review nondefault configurations related to user information exposure.
- Restrict access to trusted authenticated users until fixed.
Validation and detection
- Inventory IBM BAW, BPM, and Cloud Pak for Automation versions.
- Confirm whether listed nondefault configurations are enabled.
- Verify IBM-recommended fixes or updates are applied.
- Test that low-privileged users cannot view another user’s sensitive information.
- Review access logs for unusual user-profile or workflow data access.
