An issue was discovered in GLPI through 9.2.1. The application is affected by XSS in the query string to front/preference.php. An attacker is able to create a malicious URL that, if opened by an authenticated user with debug privilege, will execute JavaScript code supplied by the attacker. The attacker-supplied code can perform a wide variety of actions, such as stealing the victim's session token or login credentials, performing arbitrary actions on the victim's behalf, and logging their keystrokes.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
