This vulnarability is affecting versions of the Jakarta Multipart parser in Apache Struts 2 2.3.x before 2.3.32 and 2.5.x before 2.5.10.1, since it mishandles file upload, which allows remote attackers to execute arbitrary commands via a #cmd= string in a crafted Content-Type HTTP header, as exploited in the wild in March 2017.
As MANIFEST.MF states as following, the Struts version is 1.2.9. So,we may conclude SiteMinder is not affected by this CVE.
