Couchbase Server 4.0.0, 4.1.0, 4.1.1, 4.5.0, 4.5.1, 4.6.0 through 4.6.5, 5.0.0, 5.1.1, 5.5.0 and 5.5.1 have Insecure Permissions for the projector and indexer REST endpoints (they allow unauthenticated access).The /settings REST endpoint exposed by the projector process is an endpoint that administrators can use for various tasks such as updating configuration and collecting performance profiles. The endpoint was unauthenticated and has been updated to only allow authenticated users to access these administrative APIs. Couchbase Server 4.0.0, 4.1.0, 4.1.1, 4.5.0, 4.5.1, 4.6.0 a 4.6.5, 5.0.0, 5.1.1, 5.5.0 y 5.5.1 tienen permisos inseguros para puntos finales REST del proyector y del indexador (permiten el acceso no autenticado). El punto final REST / settings expuesto por el proceso del proyector es un punto final que los administradores pueden usar para diversas tareas, como actualizar la configuración y recopilar perfiles de rendimiento. El punto final no se autenticó y se actualizó para permitir solo a los usuarios autenticados acceder a estas API administrativas. • https://www.couchbase.com/resources/security#SecurityAlerts • CWE-276: Incorrect Default Permissions •

In versions of Couchbase Server prior to 5.0, the bucket named "default" was a special bucket that allowed read and write access without authentication. As part of 5.0, the behavior of all buckets including "default" were changed to only allow access by authenticated users with sufficient authorization. However, users were allowed unauthenticated and unauthorized access to the "default" bucket if the properties of this bucket were edited. This has been fixed in versions 5.1.0 and 5.5.0. En las versiones de Couchbase Server anteriores a la version 5.0, el depósito denominado "predeterminado" era un depósito especial que permitía el acceso de lectura y escritura sin autenticación. • https://www.couchbase.com/resources/security#SecurityAlerts • CWE-306: Missing Authentication for Critical Function •

In Couchbase Server 5.0.0, when an invalid Remote Cluster Certificate was entered as part of the reference creation, XDCR did not parse and check the certificate signature. It then accepted the invalid certificate and attempted to use it to establish future connections to the remote cluster. This has been fixed in version 5.5.0. XDCR now checks the validity of the certificate thoroughly and prevents a remote cluster reference from being created with an invalid certificate. En Couchbase Server versión 5.0.0, cuando se ingresó un Certificado de clúster remoto no válido como parte de la creación de referencia, XDCR no analizó ni verificó la firma del certificado. • https://www.couchbase.com/resources/security#SecurityAlerts • CWE-295: Improper Certificate Validation •

In Couchbase Server 4.6.3 and 5.5.0, secondary indexing encodes the entries to be indexed using collatejson. When index entries contain certain characters like \t, <, >, it caused buffer overrun as encoded string would be much larger than accounted for, causing indexer service to crash and restart. This has been remedied in versions 5.1.2 and 5.5.2 to ensure buffer always grows as needed for any input. En Couchbase Server versiones, 4.6.3 y 5.5.0, la indexación secundaria codifica las entradas que se indexarán mediante collatejson. Cuando las entradas de índice contienen ciertos caracteres como \ t, <,>, se produce el desbordamiento del búfer ya que la cadena codificada sería mucho más grande de lo que se tiene en cuenta, lo que hace que el servicio del indexador se bloquee y reinicie. • https://www.couchbase.com/resources/security#SecurityAlerts • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=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. • https://www.couchbase.com/resources/security#SecurityAlerts • CWE-335: Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG) •
