The .phtml (executable extension) defeats the "blacklist" approach taken in this app in regards to allowable file extensions. Which is searching for 'php' as the last 3 characters i.e the extension. PHTML along w/ php2..php3 and so on defeated this filter. You get a shell in the context of the web server.
