CVE-2019-11495

In Couchbase Server 5.1.1, the cookie used for intra-node communication was not generated securely. Couchbase Server uses erlang:now() to seed the PRNG which results in a small search space for potential random seeds that could then be used to brute force the cookie and execute code against a remote system. This has been fixed in version 6.0.0.

En Couchbase Server versión 5.1.1, la cookie utilizada para la comunicación dentro del nodo no se genera de forma segura. Couchbase Server usa erlang:now() para generar el PRNG, lo que da como resultado un pequeño espacio de búsqueda de posibles semillas aleatorias que luego podrían usarse para realizar un ataque de fuerza bruta sobre la cookie y ejecutar el código contra un sistema remoto. Esto se ha solucionado en la versión 6.0.0.
