Is there a way in C++/windows to get the exe/DLL image base address? thanks :)
回答1:
If you load the binary into your own process you can use GetModuleHandle. It returns a HMODULE, but that is the same as HINSTANCE and the base address.
If you want to know what base address the binary prefers you should read the PE header. See here and look for the ImageBase field in IMAGE_OPTIONAL_HEADER.
Edit: GetModuleHandle(NULL) will return the base address (altough the specified type is HMODULE) for the current process.

If you are examining an DLL or EXE file on disk, use the dumpbin utility. It in installed with Visual Studio or the SDK.
Example Output of dumpbin /headers:

I found that the most convenient and accurate way to get module's base address (and in-memory image size) is through GetModuleInformation (include psapi.h, link to psapi.lib):
MODULEINFO module_info; memset(&module_info, 0, sizeof(module_info));
if (GetModuleInformation(GetCurrentProcess(), hModule, &module_info, sizeof(module_info))) {
DWORD module_size = module_info.SizeOfImage;
BYTE * module_ptr = (BYTE*)module_info.lpBaseOfDll;
// ...
}

If you want to get your own ImageBase Address from inside a DLL/EXE then how about this:
#include <winnt.h>
EXTERN_C IMAGE_DOS_HEADER __ImageBase;

If you want to enumerate all process's modules, you can also use CreateToolhelp32Snapshot:
#include <windows.h>
#include <tlhelp32.h>
std::vector<std::pair<std::string, uint32_t> > base_addresses;
// take a snapshot of all modules in the specified process
HANDLE snaphot_handle = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, 0);
if (snaphot_handle != INVALID_HANDLE_VALUE)
{
// first module
MODULEENTRY32 mod_entry;
mod_entry.dwSize = sizeof(mod_entry);
if (Module32First(snaphot_handle, &mod_entry))
{
// iterate through the module list of the process
do
{
base_addresses.push_back(
std::make_pair(mod_entry.szModule,
static_cast<uint32_t>(mod_entry.modBaseAddr));
} while (Module32Next(snaphot_handle, &mod_entry));
}
CloseHandle(snaphot_handle);
}

Find below code to find Image Base Address in CPP :
#include<windows.h>
#include<iostream>
int main()
{
LPCSTR fileName="inputFile.exe";
HANDLE hFile;
HANDLE hFileMapping;
LPVOID lpFileBase;
PIMAGE_DOS_HEADER dosHeader;
PIMAGE_NT_HEADERS peHeader;
PIMAGE_SECTION_HEADER sectionHeader;
hFile = CreateFileA(fileName,GENERIC_READ,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,0);
if(hFile==INVALID_HANDLE_VALUE)
{
std::cout<<"\n CreateFile failed \n";
return 1;
}
hFileMapping = CreateFileMapping(hFile,NULL,PAGE_READONLY,0,0,NULL);
if(hFileMapping==0)
{
std::cout<<"\n CreateFileMapping failed \n";
CloseHandle(hFile);
return 1;
}
lpFileBase = MapViewOfFile(hFileMapping,FILE_MAP_READ,0,0,0);
if(lpFileBase==0)
{
std::cout<<"\n MapViewOfFile failed \n";
CloseHandle(hFileMapping);
CloseHandle(hFile);
return 1;
}
dosHeader = (PIMAGE_DOS_HEADER) lpFileBase;
if(dosHeader->e_magic==IMAGE_DOS_SIGNATURE)
{
std::cout<<"\n DOS Signature (MZ) Matched \n";
peHeader = (PIMAGE_NT_HEADERS) ((u_char*)dosHeader+dosHeader->e_lfanew);
if(peHeader->Signature==IMAGE_NT_SIGNATURE)
{
std::cout<<"\n PE Signature (PE) Matched \n";
//once found valid exe or dll
std::cout<<"\n Image Base : "<<std::hex<<peHeader->OptionalHeader.ImageBase;
}
else
{
return 1;
}
}
else
{
return 1;
}
return 0;
}
