[求助]win7下端口进程对应关系
-

最近碰到一个应用程序兼容问题，winxp下面的应用程序，移植到win7下面产生了一个功能的缺失，这个功能就是进程端口对应关系列表失去。以前是使用xp下的隐藏函数AllocateAndGetUdpExTableFromStack，AllocateAndGetTcpExTableFromStack来得到这样的功能的。但是现在这个函数在win7下不能正常使用。所以就想到了先用
ZwQuerySystemInformation获取一个进程下所有的句柄，之后把所有file类型的handle都转换到自己的进程，然后强制转化成socket类型，在使用getsockname等一系列函数来获取地址。但是似乎这个方法不成立，不知道是不是自己的写法有问题，提上来求助一下，希望大家能给个建议。
1.全局变量以及函数定义
#define NT_SUCCESS(status) ((NTSTATUS)(status)>=0)
typedef LONG NTSTATUS;
typedef enum _SYSTEM_INFORMATION_CLASS // Q S

SystemGlobalFlag, // 09 Y Y
SystemNotImplemented2, // 10 Y N
SystemModuleInformation, // 11 Y N
SystemLockInformation, // 12 Y N
SystemNotImplemented3, // 13 Y N
SystemNotImplemented4, // 14 Y N
SystemNotImplemented5, // 15 Y N

} SYSTEM_INFORMATION_CLASS;
typedef NTSTATUS ( __stdcall *ZWQUERYSYSTEMINFORMATION)(

IN OUT PVOID SystemInformation,
IN ULONG SystemInformationLength,
OUT PULONG ReturnLength OPTIONAL);
typedef ULONG(__stdcall *RTLNTSTATUSTODOSERROR)(IN NTSTATUS Status);
RTLNTSTATUSTODOSERROR fn_RtlNtStatusToDosError;
ZWQUERYSYSTEMINFORMATION fn_ZwQuerySystemInformation;
typedef struct _SYSTEM_MODULE_INFORMATION // Information Class 11
{
ULONG Reserved[2];
PVOID Base;
ULONG Size;
ULONG Flags;
USHORT Index;
USHORT Unknown;

} SYSTEM_HANDLE_INFORMATION_EX, *PSYSTEM_HANDLE_INFORMATION_EX;
2.OnInitDialog()初始化函数变量的地址
HMODULE ntdll_dll=NULL;
if((ntdll_dll=GetModuleHandle("ntdll.dll"))==NULL)
{
MessageBox("GetModuleHandle() failed");
return( FALSE );
}
if(!(fn_ZwQuerySystemInformation=(ZWQUERYSYSTEMINFORMATION)GetProcAddress(ntdll_dll,
"ZwQuerySystemInformation")))
{
MessageBox("GetProcAddress() failed");
return( FALSE );
}
if(!(fn_RtlNtStatusToDosError=(RTLNTSTATUSTODOSERROR)GetProcAddress( ntdll_dll,
"RtlNtStatusToDosError")))
{
MessageBox("GetProcAddress() failed");
return( FALSE );
}
WSADATA wsaData;
int iResult = WSAStartup(MAKEWORD(1,1), &wsaData);
if (iResult != NO_ERROR)
MessageBox("Error at WSAStartup()\n");
3.在OnButton1() 里面做句柄的获取转换等等工作
NTSTATUS status;
PSYSTEM_MODULE_INFORMATION module=NULL;
PSYSTEM_HANDLE_INFORMATION_EX pHandle=NULL;
ULONG n=0;
ULONG i=0;
void *buf=NULL;
EnablePrivilege(SE_DEBUG_NAME);

return;
}
memset(buf,0,dwSize);
status=fn_ZwQuerySystemInformation(SystemHandleInformation,buf,dwSize,&n);
while(!NT_SUCCESS( status ))
{
char *errMsg;
FormatMessage( FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM, NULL,
fn_RtlNtStatusToDosError(status),
MAKELANGID(LANG_NEUTRAL,SUBLANG_DEFAULT),
(LPTSTR)&errMsg,0,NULL);
if(buf!=NULL)
free(buf);
dwSize+=n;
if(dwSize>524288)
return;
if(NULL==(buf=malloc(dwSize)))
{
MessageBox("malloc() failed");
return;
}
memset(buf,0,dwSize);
status=fn_ZwQuerySystemInformation(SystemHandleInformation,buf,dwSize,&n);
// MessageBox(errMsg);
}
pHandle=(PSYSTEM_HANDLE_INFORMATION_EX)buf;
for(i =0;i<pHandle->NumberOfHandles;i++)
{
CString strTmp,strTmp1;
if(pHandle->Information[i].ObjType==0x1c||
pHandle->Information[i].ObjType==0x1a)
{
strTmp.Format("PID:%d/Addr:0x%08X(socket)/Handle:%d/\n",pHandle->Information[i].dwPid,
pHandle->Information[i].dwKeObject,pHandle->Information[i].HndlOffset);
HANDLE hTmp=NULL;
HANDLE srcFartherHandle=OpenProcess(WRITE_DAC,FALSE,pHandle->Information[i].dwPid);
if(srcFartherHandle!=NULL)
{
AdjustDacl(srcFartherHandle);
srcFartherHandle=OpenProcess(PROCESS_DUP_HANDLE,true,pHandle->Information[i].dwPid);
if(srcFartherHandle==NULL)
continue;
HANDLE desFartherHandle=GetCurrentProcess();
DuplicateHandle(srcFartherHandle,(HANDLE)pHandle->Information[i].HndlOffset,desFartherHandle,&hTmp,
STANDARD_RIGHTS_REQUIRED,true,0);
if(hTmp==NULL)
{
CloseHandle(srcFartherHandle);
continue;
}
sockaddr_in name = {0};
name.sin_family=AF_INET;
int namelen=sizeof(sockaddr_in);
SOCKET s=(SOCKET)hTmp;
int iRet =getsockname(s,(sockaddr*)&name,&namelen);
if ( iRet != SOCKET_ERROR )
{
int sockType = 0;
int optlen = 4;
iRet = getsockopt( s, SOL_SOCKET, SO_TYPE, (char*)&sockType, &optlen );
//+++++++++++ 显示Socket的进程ID、端口、类型、目的IP和端口 ++++++++++++
sockaddr_in peername = {0};
int peernamelen = sizeof(sockaddr_in);
iRet = getpeername(s,(sockaddr*)&peername, &peernamelen );
char szSocket[64];
sprintf( szSocket, "PID=%4d PORT=%5d %d DestIP=%s:%d",
pHandle->Information[i].dwPid, ntohs(name.sin_port),sockType,
inet_ntoa( peername.sin_addr ) , ntohs(peername.sin_port));
strTmp+=szSocket;
//+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
}
else
{
CString strErr;
strErr.Format("err getsockname %d",WSAGetLastError());
strTmp+=strErr;
}
}
}else
strTmp.Format("PID:%d/Addr:0x%08X/Handle:%d\n",pHandle->Information[i].dwPid,
pHandle->Information[i].dwKeObject,pHandle->Information[i].HndlOffset);
int iCountItems=m_ListLog.GetItemCount();
strTmp1.Format("%d",i);
m_ListLog.InsertItem(iCountItems,strTmp1);
m_ListLog.SetItemText(iCountItems,1,strTmp);
}
if(buf!=NULL)
{
free(buf);
buf=NULL;
}
return;
4.其中用到的全局函数
//提权
BOOL EnablePrivilege(char *privilegeName)
{
HANDLE hToken=NULL;
HANDLE hCurrent=GetCurrentProcess();
if(0==(int)hCurrent)
return FALSE;
if (!OpenProcessToken(hCurrent,
TOKEN_ADJUST_PRIVILEGES|TOKEN_QUERY,
&hToken))
{
return FALSE;
}
TOKEN_PRIVILEGES tkp;
LookupPrivilegeValue(NULL, privilegeName , &tkp.Privileges[0].Luid);
tkp.PrivilegeCount = 1;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, NULL, 0);
BOOL bEnabled = (GetLastError() == ERROR_SUCCESS);
CloseHandle(hToken);
return bEnabled;
}
//转换安全表
void AdjustDacl( HANDLE hProcess )
{
SID world={SID_REVISION,1,SECURITY_WORLD_SID_AUTHORITY,0};
LPTSTR ptstrName=(LPTSTR)&world;
EXPLICIT_ACCESS ea=
{STANDARD_RIGHTS_ALL|SPECIFIC_RIGHTS_ALL,
SET_ACCESS,NO_INHERITANCE,
{0,NO_MULTIPLE_TRUSTEE,TRUSTEE_IS_SID,
TRUSTEE_IS_USER,ptstrName}};
ACL *pdacl=0;
SetEntriesInAcl(1,&ea,0,&pdacl);
SetSecurityInfo(hProcess,SE_KERNEL_OBJECT,DACL_SECURITY_INFORMATION,0,0,pdacl,0);
LocalFree(pdacl);
}
以上代码获取句柄没有问题可是碰到对应关系就丑大了。
运行结果在附件里面，附件里面还有一个应用程序是微软自己开发的，它可以完成端口进程的监控，因为使用了大量的隐藏api，本人的逆向又不是很强，所以无法分析到结果，如果大牛想看看，可以逆向一下。谢谢。
