Descriptions

A vulnerability has been identified in SIMATIC HMI Unified Comfort Panels (All versions <= V16). Affected devices insufficiently validate authentication attempts as the information given can be truncated to match only a set number of characters versus the whole provided string. This could allow a remote attacker to discover user passwords and obtain access to the Sm@rt Server via a brute-force attack.

Se ha identificado una vulnerabilidad en SIMATIC HMI United Comfort Panels (todas las versiones anteriores o iguales a la versión V16). Los dispositivos afectados validan de manera insuficiente los intentos de autenticación, ya que la información entregada puede ser truncada para que coincida solo con un número determinado de caracteres frente a la cadena completa proporcionada. Esto podría permitir a un atacante remoto detectar las contraseñas de los usuarios y obtener acceso al Servidor Sm@rt mediante un ataque de fuerza bruta
