Descriptions

In GLPI before version 9.5.2, the `install/install.php` endpoint insecurely stores user input into the database as `url_base` and `url_base_api`. These settings are referenced throughout the application and allow for vulnerabilities like Cross-Site Scripting and Insecure Redirection Since authentication is not required to perform these changes,anyone could point these fields at malicious websites or form input in a way to trigger XSS. Leveraging JavaScript it's possible to steal cookies, perform actions as the user, etc. The issue is patched in version 9.5.2.

En GLPI versiones anteriores a 9.5.2, el endpoint "install/install.php" almacena de forma no segura la entrada del usuario en la base de datos como "url_base" y "url_base_api". Se hace referencia a estas configuraciones en toda la aplicación y permiten vulnerabilidades como Cross-Site Scripting y Redireccionamiento No Seguro. Dado que no se requiere autenticación para realizar estos cambios, cualquiera podría apuntar estos campos a sitios web maliciosos o ingresar datos de formulario para desencadenar un XSS. Aprovechando JavaScript es posible robar cookies, realizar acciones como el usuario, etc. El problema está parcheado en la versión 9.5.2
