Descriptions

An issue was discovered on Mitsubishi Electric ME-RTU devices through 2.02 and INEA ME-RTU devices through 3.0. Hard-coded SSH keys allow an attacker to gain unauthorised access or disclose encrypted data on the RTU due to the keys not being regenerated on initial installation or with firmware updates. In other words, these devices use private-key values in /etc/ssh/ssh_host_rsa_key, /etc/ssh/ssh_host_ecdsa_key, and /etc/ssh/ssh_host_dsa_key files that are publicly available from the vendor web sites.

Se detectó un problema en los dispositivos Mitsubishi Electric ME-RTU versiones hasta la versión 2.02 y los dispositivos INEA ME-RTU versiones hasta la versión 3.0. Las claves SSH embebidas permiten a un atacante conseguir acceso no autorizado o divulgar datos cifrados en la RTU debido a que las claves no son regeneradas en la instalación inicial o con las actualizaciones de firmware. En otras palabras, estos dispositivos usan valores de clave privada en los archivos /etc/ssh/ssh_host_rsa_key, /etc/ssh/ssh_host_ecdsa_key, y /etc/ssh/ssh_host_dsa_key, que están disponibles públicamente en los sitios web del proveedor.
