This module exploits a remote code execution vunlerability in Apache Struts
version 2.3.5 - 2.3.31, and 2.5 - 2.5.10. Remote Code Execution can be performed
via http Content-Type header.
Native payloads will be converted to executables and dropped in the
server's temp dir. If this fails, try a cmd/* payload, which won't
have to write to the disk.
