Descriptions

Certain Canon devices manufactured in 2012 through 2020 (such as imageRUNNER ADVANCE iR-ADV C5250), when Catwalk Server is enabled for HTTP access, allow remote attackers to modify an e-mail address setting, and thus cause the device to send sensitive information through e-mail to the attacker. For example, an incoming FAX may be sent through e-mail to the attacker. This occurs when a PIN is not required for General User Mode, as exploited in the wild in August 2021.

Determinados dispositivos de Canon fabricados entre 2012 hasta 2020 (como el imageRUNNER ADVANCE iR-ADV C5250), cuando el servidor Catwalk está habilitado para el acceso HTTP, permiten a atacantes remotos modificar la configuración de una dirección de correo electrónico y, por tanto, causar que el dispositivo envíe información confidencial mediante el correo electrónico al atacante. Por ejemplo, un FAX entrante puede enviarse mediante correo electrónico al atacante. Esto ocurre cuando no es requerido un PIN para el modo de Usuario General, como se explotó "in the wild" en agosto de 2021.
