The affected products can be vulnerable in up to the following two different scenarios:

  • The product bundles WebSphere Application Server. The Integrated Solution Console in WebSphere Application Server V7 and earlier uses a vulnerable version of the struts library. For these products you need to apply a fix for WebSphere Application Server.
  • WebSphere Lombardi Edition and IBM Business Process Manager include various user interface components that make use of an additional instance of the vulnerable library and, therefore, need their own fix.
  • Affected Products and Versions
