Descriptions

In Couchbase Sync Gateway 2.1.2, an attacker with access to the Sync Gateway’s public REST API was able to issue additional N1QL statements and extract sensitive data or call arbitrary N1QL functions through the parameters "startkey" and "endkey" on the "_all_docs" endpoint. By issuing nested queries with CPU-intensive operations they may have been able to cause increased resource usage and denial of service conditions. The _all_docs endpoint is not required for Couchbase Mobile replication and external access to this REST endpoint has been blocked to mitigate this issue. This issue has been fixed in versions 2.5.0 and 2.1.3.

En Couchbase Sync Gateway 2.1.2, un atacante con acceso a la API REST pública de Sync Gateway pudo emitir sentencias N1QL adicionales y extraer datos confidenciales o llamar a funciones N1QL arbitrarias a través de los parámetros "startkey" y "endkey" en "_all_docs" punto final. Al emitir consultas anidadas con operaciones intensivas de CPU, pueden haber causado un mayor uso de recursos y condiciones de denegación de servicio. El punto final _all_docs no es necesario para la replicación de Couchbase Mobile y el acceso externo a este punto final REST se ha bloqueado para mitigar este problema. Este problema se ha solucionado en las versiones 2.5.0 y 2.1.3.
