## Información Básica

**Apache Cassandra** es una **base de datos distribuida** **altamente escalable** y **de alto rendimiento** diseñada para manejar **grandes cantidades de datos** a través de muchos **servidores comunes**, proporcionando **alta disponibilidad** sin **punto único de falla**. Es un tipo de **base de datos NoSQL**.

En varios casos, puede encontrar que Cassandra acepta **cualquier credencial** (ya que no hay ninguna configurada) y esto podría permitir potencialmente a un atacante **enumerar** la base de datos.

**Puerto por defecto:** 9042,9160
```
PORT     STATE SERVICE   REASON
9042/tcp open  cassandra-native Apache Cassandra 3.10 or later (native protocol versions 3/v3, 4/v4, 5/v5-beta)
9160/tcp open  cassandra syn-ack
```
## Enumeración

### Manual
```bash
pip install cqlsh
cqlsh <IP>
#Basic info enumeration
SELECT cluster_name, thrift_version, data_center, partitioner, native_protocol_version, rack, release_version from system.local;
#Keyspace enumeration
SELECT keyspace_name FROM system.schema_keyspaces;
desc <Keyspace_name>    #Decribe that DB
desc system_auth        #Describe the DB called system_auth
SELECT * from system_auth.roles;  #Retreive that info, can contain credential hashes
SELECT * from logdb.user_auth;    #Can contain credential hashes
SELECT * from logdb.user;
SELECT * from configuration."config";
```
### Automatizado

No hay muchas opciones aquí y nmap no obtiene mucha información.
```bash
nmap -sV --script cassandra-info -p <PORT> <IP>
```
### [**Fuerza bruta**](../generic-methodologies-and-resources/brute-force.md#cassandra)

### **Shodan**

`port:9160 Cluster`\
`port:9042 "Versión de protocolo no válida o no soportada"`
