Find out more about CVE-2017-5638 from the MITRE CVE dictionary dictionary and NIST NVD.
This issue did not affect any of the Red Hat products as they did not include the Apache Struts 2 package. Additionally it does not appear that struts 1 is affected by this vulnerability (the affected code does not appear to be present in struts 1). Additionally it does not appear that Red Hat has backported any code from struts 2 to struts 1 as the code bases are quite different and backporting any significant code would be a major effort with questionable results due to compatibility issues.
