How the Exploit Works

The vulnerability stems from improper input validation in the onCreate function of MediaProjectionPermissionActivity.java. This flaw allows a malicious app to bypass the permission mechanism and obtain a token enabling screen recording capabilities. This kind of privilege escalation can potentially allow an attacker to record sensitive activities on the screen, leading to data leakage or even a full system compromise.

Conceptual Example Code

While the exact exploitation method for this vulnerability is dependent on the specific application and environment, a conceptual example of exploiting this vulnerability might look like this:

public class MaliciousApp extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
MediaProjectionManager manager = (MediaProjectionManager) getSystemService(Context.MEDIA_PROJECTION_SERVICE);
Intent intent = new Intent(manager.ACTION_MEDIA_PROJECTION);
intent.putExtra("android.intent.extra.INTENT", getMaliciousIntent());
startActivityForResult(intent, REQ_CODE);
}
private Intent getMaliciousIntent() {
// Returns an intent with malicious data or actions
}
}

Mitigation Guidance

To mitigate this vulnerability, it is recommended to apply the official vendor patch. If a patch is not available or cannot be applied immediately, use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary countermeasure. Regularly review your application and system logs for any suspicious activity.

Overview

CVE-2025-26439 is a significant cybersecurity vulnerability that affects the AccessibilitySettingsUtils.java component. It has the potential to compromise systems and result in data leakage. The flaw poses a serious threat to system administrators and users alike, due to the ease of exploitation and its potential impact on system integrity.

Vulnerability Summary

CVE ID: CVE-2025-26439
Severity: High (7.8 CVSS)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: Local escalation of privilege, system compromise or data leakage

Affected Products

Product | Affected Versions

Android OS | Versions prior to security patch level 2025-03-01

How the Exploit Works

The flaw lies in getComponentName of AccessibilitySettingsUtils.java, where a logic error enables a malicious Talkback service to be activated instead of the system component. This flaw allows an attacker with local access to escalate their privilege level without requiring any additional execution privileges or user interaction, potentially leading to system compromise or data leakage.

Conceptual Example Code

This is a conceptual representation of how the vulnerability might be exploited:

public class MaliciousTalkBackService extends AccessibilityService {
@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
// Code to perform malicious actions
}
}

In this example, a malicious AccessibilityService (named `MaliciousTalkBackService`) is defined. When an accessibility event occurs, the malicious service is activated, bypassing the intended system component. The malicious code within the `onAccessibilityEvent()` method is then executed, leading to local privilege escalation.

Mitigation Guidance

Affected users are advised to apply the latest vendor security patches, which address this vulnerability. In case patches are not immediately available or applicable, the use of Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) can serve as temporary mitigation measures. These tools can help in detecting and blocking attempts to exploit this vulnerability. However, they should not be considered as a long-term solution, and patching the affected systems should remain a priority.

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.

Vulnerability Summary

CVE ID: CVE-2025-22414
Severity: High (7.8/10)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: Bypass of security measures leading to local privilege escalation, potential system compromise or data leakage

Affected Products

Product | Affected Versions

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.

Overview

CVE-2025-48558 is a high-severity vulnerability that targets the BatteryService.java functions. The vulnerability arises from the potential hijacking of implicit intent intended for system apps. Cybercriminals could exploit this vulnerability to escalate their privileges locally without the need for additional execution privileges or user interaction. The threat of system compromise or data leakage is a significant concern for businesses and individuals.

Vulnerability Summary

CVE ID: CVE-2025-48558
Severity: High (CVSS: 7.8)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: Local escalation of privilege, potential system compromise, or data leakage

Affected Products

Product | Affected Versions

Android OS | Versions 8.0 – 11.0
Custom Android ROMs | All versions using BatteryService.java

How the Exploit Works

The vulnerability resides in multiple functions of BatteryService.java. The flaw can lead to an implicit intent hijacking due to incorrect handling of certain system-level operations. An attacker exploiting this vulnerability can intercept and manipulate these implicit intents to escalate their privileges within the system. This can be done without any additional execution privileges and does not require user interaction.

Conceptual Example Code

The following pseudocode provides a conceptual example of how the vulnerability could be exploited:

Intent maliciousIntent = new Intent();
maliciousIntent.setFlags(Intent.FLAG_RECEIVER_FOREGROUND);
maliciousIntent.setComponent(new ComponentName("com.system.app","com.system.app.Receiver"));
Bundle maliciousBundle = new Bundle();
maliciousBundle.putString("extra_key","malicious_value");
maliciousIntent.putExtras(maliciousBundle);
context.sendBroadcast(maliciousIntent);

In this example, the attacker creates a malicious intent, sets it as a foreground receiver, and uses it to target a system app’s receiver. The malicious intent contains an extra bundle with a malicious value that could be used to cause unexpected behavior in the targeted system app.

Mitigation Guidance

The primary mitigation method for this vulnerability is to apply the vendor patch as soon as it becomes available. In the meantime, or if a patch is not yet available, temporary mitigation can be achieved by using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block potential exploit attempts.
