Descriptions

An issue was discovered in Couchbase Sync Gateway 3.x before 3.0.2. Admin credentials are not verified when using X.509 client-certificate authentication from Sync Gateway to Couchbase Server. When Sync Gateway is configured to authenticate with Couchbase Server using X.509 client certificates, the admin credentials provided to the Admin REST API are ignored, resulting in privilege escalation for unauthenticated users. The Public REST API is not impacted by this issue. A workaround is to replace X.509 certificate based authentication with Username and Password authentication inside the bootstrap configuration.

Se ha detectado un problema en Couchbase Sync Gateway versiones 3.x anteriores a 3.0.2. Las credenciales de administrador no son verificadas cuando es usada la autenticación de certificado de cliente X.509 desde Sync Gateway a Couchbase Server. Cuando Sync Gateway está configurado para autenticarse con el Servidor Couchbase usando certificados de cliente X.509, las credenciales de administrador proporcionadas a la API REST de administración son ignoradas, resultando en una escalada de privilegios para los usuarios no autenticados. La API REST pública no está afectada por este problema. Una mitigación es sustituir la autenticación basada en certificados X.509 por la autenticación de nombre de usuario y contraseña dentro de la configuración de arranque
