If providing a mitigation add this line to this section:
IBM recommends that you review your entire environment to identify vulnerable
releases of the Open Source Apache Struts Vulnerabilities Collections and
take appropriate mitigation and remediation actions.
Important note: IBM strongly suggests that all System z customers subscribe
to the System z Security Portal to receive the latest critical System
z security and integrity service. If you are not subscribed, see the
instructions on the System z Security web site. Security and integrity
APARs and associated fixes will be posted to this portal. IBM suggests
reviewing the CVSS scores and applying all security or integrity fixes as
soon as possible to minimize any potential risk.
