Descriptions

D-Link DIR-850L REV. A (with firmware through FW114WWb07_h2ab_beta1) and REV. B (with firmware through FW208WWb02) devices use the same hardcoded /etc/stunnel.key private key across different customers' installations, which allows remote attackers to defeat the HTTPS cryptographic protection mechanisms by leveraging knowledge of this key from another installation.

Los dispositivos D-Link DIR-850L REV. A (con firmware hasta la versión FW114WWb07_h2ab_beta1) y REV. B (con firmware hasta la versión FW208WWb02) emplean la misma clave embebida /etc/stunnel.key a lo largo de instalaciones de diferentes clientes, lo que permite que atacantes remotos superen los mecanismos de protección criptográfica HTTPS aprovechando el hecho de que conocen esta clave por otra instalación.
