## Basic Information

**Apache Cassandra**는 **고도로 확장 가능**하고, **고성능**의 분산 데이터베이스로, 많은 **상용 서버**에 걸쳐 **대량의 데이터**를 처리하도록 설계되었으며, **단일 실패 지점** 없이 **높은 가용성**을 제공합니다. 이는 **NoSQL 데이터베이스**의 일종입니다.

여러 경우에 Cassandra가 **구성된 자격 증명**이 없기 때문에 **모든 자격 증명**을 수용할 수 있으며, 이는 공격자가 데이터베이스를 **열거**할 수 있게 할 수 있습니다.

**기본 포트:** 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
```
## Enumeration

### 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";
```
### 자동화된

여기에는 많은 옵션이 없으며 nmap은 많은 정보를 얻지 못합니다.
```bash
nmap -sV --script cassandra-info -p <PORT> <IP>
```
### [**Brute force**](../generic-methodologies-and-resources/brute-force.md#cassandra)

### **Shodan**

`port:9160 Cluster`\
`port:9042 "Invalid or unsupported protocol version"`
