A remote code execution issue was discovered in GLPI through 9.2.1. There is a race condition that allows temporary access to an uploaded executable file that will be disallowed. The application allows an authenticated user to upload a file when he/she creates a new ticket via front/fileupload.php. This feature is protected using different types of security features like the check on the file's extension. However, the application uploads and creates a file, though this file is not allowed, and then deletes the file in the uploadFiles method in inc/glpiuploaderhandler.class.php.

SQL injection exists in front/devicesoundcard.php in GLPI before 9.1.5 via the start parameter.

front/backup.php in GLPI before 9.1.5 allows remote authenticated administrators to delete arbitrary files via a crafted file parameter.

GLPI before 9.1.5.1 has SQL Injection in the condition rule field, exploitable via front/rulesengine.test.php.

GLPI before 9.1.5.1 has SQL Injection in the $crit variable in inc/computer_softwareversion.class.php, exploitable via ajax/common.tabs.php.

GLPI before 9.1.5 allows SQL injection via an ajax/getDropdownValue.php request with an entity_restrict parameter that is not a list of integers.

GLPI before 0.85.3 allows remote authenticated users to create super-admin accounts by leveraging permissions to create a user and the _profiles_id parameter to front/user.form.php.

Unrestricted file upload in GLPI before 0.85.3 allows remote authenticated users to execute arbitrary code by adding a file with an executable extension as an attachment to a new ticket, then accessing it via a direct request to the file in files/_tmp/.

Directory traversal vulnerability in inc/autoload.function.php in GLPI before 0.84.8 allows remote attackers to include and execute arbitrary local files via a .._ (dot dot underscore) in an item type to the getItemForItemtype, as demonstrated by the itemtype parameter in ajax/common.tabs.php.

GLPI before 0.84.7 does not properly restrict access to cost information, which allows remote attackers to obtain sensitive information via the cost criteria in the search bar.

SQL injection vulnerability in ajax/getDropdownValue.php in GLPI before 0.85.1 allows remote authenticated users to execute arbitrary SQL commands via the condition parameter.

inc/ticket.class.php in GLPI 0.83.9 and earlier allows remote attackers to unserialize arbitrary PHP objects via the _predefined_fields parameter to front/ticket.form.php.

Multiple SQL injection vulnerabilities in GLPI before 0.83.9 allow remote attackers to execute arbitrary SQL commands via the (1) users_id_assign parameter to ajax/ticketassigninformation.php, (2) filename parameter to front/document.form.php, or (3) table parameter to ajax/comments.php.

inc/central.class.php in GLPI before 0.84.2 does not attempt to make install/install.php unavailable after an installation is completed, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks, and (1) perform a SQL injection via an Etape_4 action or (2) execute arbitrary PHP code via an update_1 action.
