Summary
Graylog before 3.3.3 lacks SSL Certificate Validation for LDAP servers. It allows use of an external user/group database stored in LDAP. The connection configuration allows the usage of unencrypted, SSL- or TLS-secured connections. Unfortunately, the Graylog client code (in all versions that support LDAP) does not implement proper certificate validation (regardless of whether the "Allow self-signed certificates" option is used). Therefore, any attacker with the ability to intercept network traffic between a Graylog server and an LDAP server is able to redirect traffic to a different LDAP server (unnoticed by the Graylog server due to the lack of certificate validation), effectively bypassing Graylog's authentication mechanism.

"value": "Graylog versiones anteriores a 3.3.3, carece de una comprobaci\u00f3n de certificado SSL para servidores LDAP. Permite el uso de una base de datos de usuarios y grupos externos almacenados en LDAP. La configuraci\u00f3n de la conexi\u00f3n permite el uso de conexiones sin cifrar, con seguridad SSL o TLS. Desafortunadamente, el c\u00f3digo del cliente Graylog (en todas las versiones que admiten LDAP) no implementa una comprobaci\u00f3n de certificado adecuada (independientemente de si se usa la opci\u00f3n \"Allow self-signed certificates\"). Por lo tanto, cualquier atacante con la capacidad de interceptar el tr\u00e1fico de red entre un servidor Graylog y un servidor LDAP puede redireccionar el tr\u00e1fico hacia un servidor LDAP diferente (desapercibido por el servidor Graylog debido a la falta de comprobaci\u00f3n del certificado), omitiendo efectivamente el mecanismo de autenticaci\u00f3n de Graylog"
