Affected Products and Versions
| Affected Product(s) | Version(s) | Status |
| IBM Business Automation Workflow containers |
V23.0.2 - V23.0.2-IF002 | affected |
| IBM Business Automation Workflow traditional | V23.0.1 - V23.0.2 V22.0.1 - V22.0.2 V21.0.1 - V21.0.3.1 V20.0.0.1 - V20.0.0.2 V19.0.0.1 - V19.0.0.3 | affected |

Remediation/Fixes
The recommended solution is to apply the Interim Fix (iFix) or Cumulative Fix (CF) containing APAR DT247523 as soon as practical.
| Affected Product(s) | Version(s) | Remediation / Fix |
|---|---|---|
| IBM Business Automation Workflow containers | V23.0.2 | Apply 23.0.2-IF003 |
| IBM Business Automation Workflow containers | V21.0.3 | Apply 21.0.3-IF031 or upgrade to 23.0.2-IF003 or later |
| IBM Business Automation Workflow containers | V23.0.1 V22.0.1 - V22.0.2 V21.0.1 - V21.0.2 V20.0.0.1 - V20.0.0.2 | Upgrade to 21.0.3-IF031 or upgrade to 23.0.2-IF003 or later |
| IBM Business Automation Workflow traditional and IBM Business Automation Workflow Enterprise Service Bus | V23.0.2 | Apply DT247523 |
| IBM Business Automation Workflow traditional | V21.0.3.1 | Apply DT247523 |
| IBM Business Automation Workflow traditional |
V23.0.1 | Upgrade to a long term support release or the latest SSCD version. See IBM Business Automation Workflow and IBM Integration Designer Software Support Lifecycle Addendum |
The fix introduces a new concept of a "ECM Document Query Authorization Service", comparable to the existing concept of "ECM Document Authorization Service" (see related information below). By implementing this service, your own code can pre-process CMIS queries sent from a client (like a Client Side Human Service) before they are forwarded to an external ECM system. The service implementation is mandatory for external ECM server definitions that have the "Always Use This Connection Information" checkbox checked, that is, when using a system account independent of the current end user. The requirement for an "ECM Document Query Authorization Service" can be globally disabled via configuration to allow a transition period when adding such services to your process apps.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
