Descriptions

GLPI before before version 9.4.6 has a vulnerability involving a default encryption key. GLPIKEY is public and is used on every instance. This means anyone can decrypt sensitive data stored using this key. It is possible to change the key before installing GLPI. But on existing instances, data must be reencrypted with the new key. Problem is we can not know which columns or rows in the database are using that; espcially from plugins. Changing the key without updating data would lend in bad password sent from glpi; but storing them again from the UI will work.

GLPI versiones anteriores a 9.4.6, presenta una vulnerabilidad que involucra una clave de cifrado predeterminada. GLPIKEY es pública y es usada en todas las instancias. Esto significa que cualquier persona puede descifrar los datos confidenciales almacenados usando esta clave. Es posible cambiar la clave antes de instalar GLPI. Pero en las instancias presentes, los datos deben ser reencriptados con la nueva clave. El problema es que no podemos saber qué columnas o filas de la base de datos están usando eso; especialmente de los plugins. Cambiar la clave sin actualizar los datos resultaría en una mala contraseña enviada desde el GLPI; pero almacenarla de nuevo desde la Interfaz de Usuario funcionará.
