## Basic Information
**InfluxDB** is an open-source **time series database (TSDB)** developed by InfluxData. TSDBs are optimized for storing and serving time series data, which consists of timestamp-value pairs. Compared to general-purpose databases, TSDBs provide significant improvements in **storage space** and **performance** for time series datasets. They employ specialized compression algorithms and can be configured to automatically remove old data. Specialized database indices also enhance query performance.
**Default port**: 8086
```
PORT STATE SERVICE VERSION
8086/tcp open http InfluxDB http admin 1.7.5
```
## Enumeration
From a pentester point of view this another database that could be storing sensitive information, so it's interesting to know how to dump all the info.
### Authentication
InfluxDB might require authentication or not
```bash
# Try unauthenticated
influx -host 'host name' -port 'port #'
> use _internal
```
If you **get an error like** this one: `ERR: unable to parse authentication credentials` it means that it's **expecting some credentials**.
```
influx –username influx –password influx_pass
```
There was a vulnerability influxdb that allowed to bypass the authentication: [**CVE-2019-20933**](https://github.com/LorenzoTullini/InfluxDB-Exploit-CVE-2019-20933)
### Manual Enumeration
The information of this example was taken from [**here**](https://oznetnerd.com/2017/06/11/getting-know-influxdb/).
#### Show databases
The found databases are `telegraf` and `internal` (you will find this one everywhere)
```bash
> show databases
name: databases
name
----
telegraf
_internal
```
#### Show tables/measurements
The [**InfluxDB documentation**](https://docs.influxdata.com/influxdb/v1.2/introduction/getting\_started/) explains that **measurements** in InfluxDB can be paralleled with SQL tables. The nomenclature of these **measurements** is indicative of their respective content, each housing data relevant to a particular entity.
```bash
> show measurements
name: measurements
name
----
cpu
disk
diskio
kernel
mem
processes
swap
system
```
#### Show columns/field keys
The field keys are like the **columns** of the database
```bash
> show field keys
name: cpu
fieldKey fieldType
-------- ---------
usage_guest float
usage_guest_nice float
usage_idle float
usage_iowait float
name: disk
fieldKey fieldType
-------- ---------
free integer
inodes_free integer
inodes_total integer
inodes_used integer
[ ... more keys ...]
```
#### Dump Table
And finally you can **dump the table** doing something like
```bash
select * from cpu
name: cpu
time cpu host usage_guest usage_guest_nice usage_idle usage_iowait usage_irq usage_nice usage_softirq usage_steal usage_system usage_user
---- --- ---- ----------- ---------------- ---------- ------------ --------- ---------- ------------- ----------- ------------ ----------
1497018760000000000 cpu-total ubuntu 0 0 99.297893681046 0 0 0 0 0 0.35105315947842414 0.35105315947842414
1497018760000000000 cpu1 ubuntu 0 0 99.69909729188728 0 0 0 0 0 0.20060180541622202 0.10030090270811101
```
{% hint style="warning" %}
In some testing with the authentication bypass it was noted that the name of the table needed to be between double quotes like: `select * from "cpu"`
{% endhint %}
### Automated Authentication
```bash
msf6 > use auxiliary/scanner/http/influxdb_enum
```
{% hint style="success" %}
