IBM WebSphere DataPower Appliances 7.1, 7.2, 7.5, 7.5.1, 7.5.2, and 7.6 is vulnerable to a XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources. IBM X-Force ID: 139023.

Security readout for executives and security teams

IBM DataPower appliances can mishandle XML input in affected 7.x releases. A remote low-privileged attacker could use XML External Entity behavior to expose sensitive data or consume memory. This matters where DataPower processes XML from users, partners, or integrated systems. Exposure is most likely in organizations running listed IBM DataPower 7.x versions that process XML data. Risk increases where XML-handling services accept input from remote users, partners, APIs, or semi-trusted internal systems. Treat as a high-priority remediation item for any exposed or integration-facing DataPower deployment. The business risk is data exposure from gateway infrastructure that often handles sensitive API and partner traffic. Mitigation focus: Identify any IBM DataPower appliances running versions 7.1 through 7.6.; Check IBM support advisory swg22015055 for fixed levels or vendor workarounds.; Apply IBM-recommended updates or mitigations through the normal change process..
