Descriptions
When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption.
Cuando el servidor está configurado para usar la autenticación confiable con un requisito de clientcert o para usar la autenticación de cert, un atacante de tipo man-in-the-middle puede inyectar consultas SQL arbitrarias cuando es establecida una conexión por primera vez, a pesar del uso de la verificación y el cifrado del certificado SSL
It was found that a PostgreSQL server could accept plain text data during the establishment of an SSL connection. When a user is requesting a certificate based authentication, an active Person in the Middle could use this flaw in order to inject arbitrary SQL commands.
