## Task 1: Website Analysis

### What port is for the web server?

Let's scan the target using `nmap`.

```
$ nmap -sC -sV 10.10.5.238 
Starting Nmap 7.92 ( https://nmap.org ) at 2023-12-07 19:48 IST

```

As we can see there are two open ports:

| Port | Service       |
| ---- | ------------- |
| 80   | http          |
| 3389 | ms-wbt-server |

### Answer

### What's the name of the Administrator

## Task 3: Final stage

### Gain initial access to the machine, what is the contents of user.txt?

We know that there is a user `sg` and a password `UmbracoIsTheBest!`.

Using the credentials we can connect to the target through RDP.

```
$ xfreerdp /v:10.10.5.238 /u:sg /p:UmbracoIsTheBest! /cert:ignore +clipboard /dynamic-resolution
```

### Can we spot the admin password?

After changing the `View` to `Show hidden items` we can go to `C\backup`.

There is file there which we don't have the permissions to read.

![](https://github.com/Knign/Write-ups/assets/110326359/87750212-b563-4100-bbe0-a1d220291dc9)

Let's see if we can change the permissions.
