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. • https://www.couchbase.com/resources/security#SecurityAlerts • CWE-335: Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG) •

In Couchbase Server 6.0.0 and 5.5.0, the eventing service exposes system diagnostic profile via an HTTP endpoint that does not require credentials on a port earmarked for internal traffic only. This has been remedied in version 6.0.1 and now requires valid credentials to access. En Couchbase Server versiones 6.0.0 y 5.5.0, el servicio de eventos expone el perfil de diagnóstico del sistema a través de un punto final HTTP que no requiere credenciales en un puerto destinado solo para tráfico interno. Esto se solucionó en la versión 6.0.1 y ahora requiere credenciales válidas para acceder. • https://www.couchbase.com/resources/security#SecurityAlerts • CWE-306: Missing Authentication for Critical Function •

An issue was discovered in Couchbase Server 5.5.x through 5.5.3 and 6.0.0. The Memcached "connections" stat block command emits a non-redacted username. The system information submitted to Couchbase as part of a bug report included the usernames for all users currently logged into the system even if the log was redacted for privacy. This has been fixed (in 5.5.4 and 6.0.1) so that usernames are tagged properly in the logs and are hashed out when the logs are redacted. Se detectó un problema en Couchbase Server versiones 5.5.x hasta 5.5.3 y versión 6.0.0. • https://www.couchbase.com/resources/security#SecurityAlerts • CWE-532: Insertion of Sensitive Information into Log File •

Some enterprises require that REST API endpoints include security-related headers in REST responses. Headers such as X-Frame-Options and X-Content-Type-Options are generally advisable, however some information security professionals additionally look for X-Permitted-Cross-Domain-Policies and X-XSS-Protection, which are more generally applicable to HTML endpoint, to be included too. These headers were not included in Couchbase Server 5.5.0 and 5.1.2 . They are now included in version 6.0.2 in responses from the Couchbase Server Views REST API (port 8092). Algunas empresas requieren que los puntos finales API REST incluyan encabezados relacionados con la seguridad en las respuestas REST. • https://www.couchbase.com/resources/security#SecurityAlerts • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
