GLPI v0.83.8 Multiple Error-based SQL Injection Vulnerabilities
Vendor: INDEPNET Development Team
Product web page: http://www.glpi-project.org
Affected version: 0.83.7 and 0.83.8
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: Input passed via the POST parameter 'users_id_assign' in
'/ajax/ticketassigninformation.php' script, POST parameter 'filename'
in '/front/document.form.php' script, and POST parameter 'table' in
'glpi/ajax/comments.php' script is not properly sanitised before
being used in SQL queries. This can be exploited by a malicious
attacker to manipulate SQL queries by injecting arbitrary SQL code
in the affected application.

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'])();
