AppPool\DefaultAppPool can enroll against the ADCS RPC endpoint and come back with a certificate for the host machine account. Outbound domain traffic from a virtual AppPool identity is authenticated as HOST$, so the default Machine template treats the CSR as a legitimate computer enrollment.
The issued cert produces a PKINIT TGT for that machine account. S4U2Self turns it into an Administrator CIFS ticket on the same box, which is local SYSTEM-equivalent access and a path to hash dump. Potato-family impersonation is not part of the chain.

#ad #adcs #iis #privesc #pkinit #s4u2self #windowsPrefixList inside the <ds:SignedInfo> InclusiveNamespaces element overflows a fixed-size buffer, corrupting adjacent nsb chunk metadata. This yields a write-what-where primitive (controlled memcpy src/dst), allowing overwrite of tx_pkt_complete_fptr and jump to attacker shellcode on the executable heap. Results in root RCE (webshell drop) when NetScaler is configured as SAML SP or IdP.
Affected: NetScaler ADC/Gateway 14.1 < 14.1-72.61 and 13.1 < 13.1-63.18

#citrix #netscaler #rce #preauth #saml #heapoverflowcdc (Client DC) and rmd (Remote Domain) request attributes, an attacker forces the Enterprise CA to query an attacker-controlled host over SMB and LDAP.
The CA then blindly trusts the returned directory objects (objectSid + dNSHostName of a real DC) and issues a certificate containing strong identity mapping for the Domain Controller. This allows successful PKINIT authentication as the DC.

Since it runs without spawning suspended processes or relying on process hollowing, it leaves virtually no obvious footprint in the system.

Due to a window during process exit where the memory management structure is cleared before file descriptors are closed, an unprivileged user can use pidfd_getfd(2) to steal open file descriptors of privileged processes, enabling unauthorized reading of root-owned files.

Так вот, доработал его для полноценной поддержки DFS
Что умеет:
- ls помечает DFS-ссылки как [DFS]
- dfs_info <dir> показывает referral: targets + TTL
- cd <DFS-папка> (в режиме follow) сам делает переподключение к target и продолжает навигацию
- Nested DFS любой глубины (стек контекстов)
- Multi-target failover: упал target → пробуем следующий
- Health-check + auto-reconnect для кэшированных коннектов
- Корректная навигация через границы DFS-root: cd .., cd ../.., cd ../../other
- Работает и с Kerberos, и с NTLM (учётки переиспользуются)
- Кэширование подключений
OPSEC (важно):
Автоматическое подключение к другому файловому хранилицу по-умолчанию выключено — чтобы не шуметь лишний раз.Включение:
# CLI:
-dfs-follow # (разрешить автоматический переход по DFS при cd)
# В шелле:
dfs_mode on # (включить follow-режим в интерактивной сессии)
Мини-пример:
# ls
Projects [DFS]
# dfs_info Projects
Target: \\fileserver-01\Projects$ (TTL: 300)
# dfs_mode on
# cd Projects
[*] DFS target: \\fileserver-01\Projects$
Реализация на уровне протокола: FSCTL_DFS_GET_REFERRALS (MS-DFSC).
