Overview

This report presents a detailed analysis of the critical vulnerability, CVE-2025-22414, found in FrpBypassAlertActivity of FrpBypassAlertActivity.java. This vulnerability, due to a missing permission check, can be exploited to bypass FRP, leading to a local escalation of privilege without needing additional execution privileges. This vulnerability impacts all users and applications that rely on this software, posing a serious threat to system integrity and data security.

FrpBypassAlertActivity.java | All versions prior to the vendor patch

How the Exploit Works

The vulnerability exists due to an absent permission check in FrpBypassAlertActivity of FrpBypassAlertActivity.java. An attacker can exploit this flaw to bypass Factory Reset Protection (FRP), which could result in a local escalation of privilege. A successful exploit does not require any user interaction and does not need any additional execution privileges, which makes this vulnerability particularly dangerous.

Conceptual Example Code

Below is a conceptual example of how the vulnerability could be exploited. In this hypothetical scenario, the attacker uses a malicious payload to exploit the missing permission check:

import android.content.Intent;
import android.os.Bundle;
public class BypassFRP {
public static void main(String[] args) {
Bundle bundle = new Bundle();
bundle.putString("EXTRA_PERMISSION_NAME", "android.permission.BYPASS_FRP");
Intent intent = new Intent("com.example.bypassfrp");
intent.putExtras(bundle);
startActivity(intent);
}
}

Please note that this is a simplified and conceptual example, and real-world exploits may be more complex and sophisticated.

Mitigation Guidance

Users are advised to apply the vendor patch as soon as it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation to monitor and block suspicious activities. Regular updates and system checks should be maintained to ensure the security of your systems.
