How the Exploit Works

The exploit takes advantage of a logic error in the setMediaButtonReceiver of multiple files. An attacker can use this error to launch arbitrary activities from the background of the system. This logic error, when exploited, enables the attacker to escalate privileges locally, potentially leading to system compromise or data leakage.

Conceptual Example Code

A conceptual example of how this vulnerability might be exploited could involve sending a malicious payload to a vulnerable endpoint. This payload could be designed to exploit the logic error and trigger the unwanted activity. The following is a simplified example:

POST /vulnerable/mediaButtonReceiver HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "launchActivity('com.example.malicious')" }

In this example, the malicious payload instructs the system to launch a malicious activity in the background, exploiting the logic error to bypass normal privilege checks.

Mitigation

To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, users can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation.

How the Exploit Works

The vulnerability exists due to a logic error in the handleKeyGestureEvent of PhoneWindowManager.java. This flaw allows attackers to bypass the lock screen without requiring additional execution privileges or user interaction. The exploit could be used to escalate privileges locally and potentially gain unauthorized access to sensitive data or system resources.

Conceptual Example Code

The following is a conceptual representation of how this vulnerability might be exploited. This is not actual exploit code, but merely illustrates the kind of approach an attacker might take:

public void exploitLockScreenBypass() {
PhoneWindowManager pwm = new PhoneWindowManager();
// bypass lock screen
pwm.handleKeyGestureEvent(new KeyGestureEvent("BYPASS_LOCK"));
// escalate privileges
pwm.escalatePrivileges();
}

Mitigation and Recommendations

A patch for this vulnerability should be applied from the vendor as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may serve as a temporary mitigation. It is also recommended to follow best practices in secure coding to avoid such logic errors in the future.

How the Exploit Works

The exploit takes advantage of a logic error in the ‘hasInteractAcrossUsersFullPermission’ function of AppInfoBase.java. This error allows an application on the secondary user to gain permissions from the primary user. The flaw does not require any additional execution privileges, and the user does not need to interact with the application for the exploit to work. This makes the exploit particularly dangerous, as it can be executed silently in the background.

Conceptual Example Code

The following pseudocode illustrates the potential exploit:

public class MaliciousApp {
public void exploit() {
AppInfoBase app = getAppInfoBase();
if (app.hasInteractAcrossUsersFullPermission()) {
escalatePrivilege(app);
}
}
private AppInfoBase getAppInfoBase() {
// Return an instance of AppInfoBase.java
}
private void escalatePrivilege(AppInfoBase app) {
// Code to escalate privilege
}
}

This pseudocode demonstrates how an application can check if it has ‘interactAcrossUsersFullPermission’ and then escalate its privileges if it does. The actual exploit would likely involve more complex code and use of obscure APIs to execute the privilege escalation. The example is simplified for understanding purposes.

Mitigation Guidance

The most effective way to mitigate this vulnerability is to apply the patch provided by the vendor. If a patch is not available, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. However, these measures only detect and prevent known exploit patterns, so they may not be fully effective. Therefore, applying the vendor’s patch as soon as it becomes available is strongly recommended.

Overview

CVE-2025-22422 is a cybersecurity vulnerability that allows potential threat actors to mislead users into approving an authentication prompt for one application, only for the result to be utilized in another. This can potentially lead to an unauthorized local escalation of privilege. The vulnerability is significant due to its potential to compromise system integrity or result in data leakage.

Vulnerability Summary

CVE ID: CVE-2025-22422
Severity: High (7.8 CVSS score)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: System compromise or potential data leakage

Affected Products

Product | Affected Versions

Application A | All versions up to 2.1.5
Application B | All versions up to 3.0.1

How the Exploit Works

The exploit takes advantage of a logic error in the code. In multiple locations, it presents an authentication prompt intended for one application to the user. However, due to the logic error, the result of this authentication is then used in another application. This allows for a local escalation of privilege without requiring any additional execution privileges.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited:

POST /authenticate/app1 HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "user_credentials": "user_app1_credentials" }
// Due to the vulnerability, the authentication result is now available also to app2
GET /restricted/data/app2 HTTP/1.1
Host: target.example.com
Authentication: Bearer token_received_from_app1_auth

Mitigation

The most effective mitigation against this exploit is to apply the security patch provided by the vendor. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. It is recommended to always keep software up-to-date and apply patches as soon as they become available.

Overview

The cybersecurity vulnerability CVE-2025-22418 presents a significant risk to the security of information systems. It arises from a “confused deputy” problem in unspecified locations, leading to a potential local escalation of privilege. This vulnerability affects systems across multiple platforms, and its exploitation does not require user interaction, making it particularly dangerous.

Vulnerability Summary

CVE ID: CVE-2025-22418
Severity: High (7.8 CVSS Score)
Attack Vector: Local
Privileges Required: None
User Interaction: Not Required
Impact: System Compromise and Data Leakage

Affected Products

Product | Affected Versions

[Product A] | [Version X.Y.Z]
[Product B] | [Version X.Y.Z]

How the Exploit Works

The exploit takes advantage of a “confused deputy” problem in certain locations of the affected system, leading to an intent redirect. This sly redirect can cause a local escalation of privilege, allowing the attacker to gain unauthorized access to privileged functionalities. The exploit doesn’t require any user interaction, meaning it can be carried out without the knowledge of the system’s user or administrator.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited:

POST /confused_deputy/redirect HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "deputy_privilege_escalation": "..." }

In this example, the attacker sends a malicious POST request to a vulnerable endpoint (`/confused_deputy/redirect`). The “deputy_privilege_escalation” is the payload that can potentially allow the attacker to escalate their privileges on the target system.

Mitigation Guidance

To mitigate this vulnerability, it is recommended to apply the vendor-released patch as soon as it becomes available. Until then, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure. Regularly updating and patching your systems can help prevent the exploitation of such vulnerabilities.

Overview

The vulnerability CVE-2025-22416 is a serious security flaw affecting ChooserActivity.java, which could allow an attacker to view other users’ images without requiring any additional execution privileges. This vulnerability poses a significant risk to user privacy and data integrity, and could potentially lead to system compromises or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-22416
Severity: High (7.8 CVSS Score)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

ChooserActivity.java | All versions prior to patch

How the Exploit Works

The exploit takes advantage of a confused deputy problem in onCreate method of ChooserActivity.java. This security flaw allows an attacker to access and view images of other users in the local system without requiring any additional execution privileges or user interaction. The vulnerability is exploited locally and does not require any special permissions or user interaction, making it a high-risk vulnerability.

Conceptual Example Code

public class Exploit {
public static void main(String[] args) {
ChooserActivity chooserActivity = new ChooserActivity();
chooserActivity.onCreate(null);
UserImage[] allImages = chooserActivity.getAllUserImages();
for (UserImage image : allImages) {
System.out.println(image.getUri());
}
}
}

In this conceptual example, an attacker creates an instance of ChooserActivity and calls the onCreate method. Then, the attacker uses the getAllUserImages method to retrieve all user images and print their URIs.

Mitigation

To mitigate the risk presented by CVE-2025-22416, it is recommended to apply the vendor-provided patch. In cases where immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. Due to the severity of this vulnerability, immediate action should be taken to secure affected systems.
