Overview

The vulnerability, indexed as CVE-2025-48552, is a critical flaw in DevicePolicyManagerService.java that potentially allows for a local escalation of privilege. All systems running the affected versions of this Java service may be at risk. Due to the high severity score and potential for system compromise or data leakage, immediate attention is required.

Vulnerability Summary

CVE ID: CVE-2025-48552
Severity: High (7.8 CVSS)
Attack Vector: Local
Privileges Required: None
User Interaction: Not Required
Impact: Potential system compromise and data leakage

Affected Products

Product | Affected Versions

DevicePolicyManagerService.java | All prior to patch

How the Exploit Works

The flaw lies in the saveGlobalProxyLocked function of DevicePolicyManagerService.java. A logic error in the code allows for desynchronization from persistence. This could potentially be exploited by an attacker to escalate their privileges locally, without needing any additional execution privileges or user interaction.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. While this is not actual exploit code, it provides a general idea of how an attacker might take advantage of the flaw.

public class Exploit {
public static void main(String[] args) {
// Obtain instance of vulnerable service
DevicePolicyManagerService service = DevicePolicyManagerService.getInstance();
// Attempt to desync the service from persistence
service.saveGlobalProxyLocked(null, null);
// If successful, escalated privileges can be used here
}
}

Mitigation Guidance

It is highly recommended to apply a vendor patch as soon as it becomes available. In the meantime, usage of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation. These tools can potentially block or alert on activity that appears to be exploiting this vulnerability.

Overview

The following report provides an in-depth analysis of a recently discovered vulnerability, CVE-2025-48546, that affects the checkPermissions function in SafeActivityOptions.java. This fault is significant as it permits potential system compromise or data leakage. This vulnerability’s severity, coupled with the fact that it requires no user interaction to exploit, makes it a critical concern for all entities using affected versions of the given software.

Vulnerability Summary

CVE ID: CVE-2025-48546
Severity: High (7.8/10)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

SafeActivityOptions.java | All versions prior to patch

How the Exploit Works

The vulnerability CVE-2025-48546 resides in the checkPermissions function of SafeActivityOptions.java. A logic error within the code allows an attacker to launch activities in the background. The attacker can exploit this vulnerability locally without needing additional execution privileges or user interaction, potentially leading to an escalation of privilege. A successful exploitation can compromise the system’s integrity or result in data leakage.

Conceptual Example Code

Here is a conceptual example of how an attacker might exploit the vulnerability:

public class ExploitCVE202548546 {
public static void main(String[] args) {
// Create an instance of SafeActivityOptions
SafeActivityOptions safeActivity = new SafeActivityOptions();
// Exploit the logic error in checkPermissions to launch a background activity
safeActivity.checkPermissions("malicious_background_activity");
}
}

This example illustrates the attacker invoking the checkPermissions method with a malicious background activity.

Remediation

To mitigate the risk posed by CVE-2025-48546, it is highly recommended to apply the vendor-provided patch. In the absence of an immediate patch, implementing a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation strategy. However, these should not be considered long-term solutions as they may not fully prevent exploitation of the vulnerability.

Overview

A high-severity vulnerability, CVE-2025-48531, has been identified within the CredentialStorage system. This vulnerability may enable a potential attacker to perform a local privilege escalation without any additional execution privileges. This exploit does not require any user interaction, making it a significant cybersecurity concern and a potential gateway to system compromise or data leakage.

Vulnerability Summary

CVE ID: CVE-2025-48531
Severity: High (CVSS: 7.8)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

CredentialStorage | All versions up to the patch

How the Exploit Works

The exploit leverages a logic error in the implementation of getCallingPackageName function in CredentialStorage. This flaw allows an attacker to bypass permissions, potentially leading to local escalation of privilege. Once the privilege level is escalated, the attacker could gain unauthorized access to sensitive data or control over the system.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. This is a pseudocode representation and is not intended to be a working exploit.

public class Exploit {
public static void main(String[] args) {
CredentialStorage cs = getCredentialStorageInstance();
cs.getCallingPackageName("malicious_app");
}
}

In the above pseudocode, the exploit attempts to call the `getCallingPackageName` function with a malicious app package name. If the system is vulnerable, this can lead to a privilege escalation.

Mitigation Guidance

To mitigate the risk associated with this vulnerability, users are advised to apply the vendor patch immediately once it becomes available. If the patch is not yet ready, temporary mitigation can be achieved by using a Web Application Firewall (WAF) or Intrusion Detection System (IDS). These systems can monitor and block suspicious activities, thus minimizing the potential for exploitation.

Overview

In this report, we are focusing on the CVE-2025-48523 vulnerability, a logic error in the onCreate function of SelectAccountActivity.java. This vulnerability allows unauthorized users to add contacts without necessary permissions, potentially leading to a local escalation of privilege. This can potentially compromise the system or leak data. The issue is especially alarming as it does not require user interaction for exploitation, making it a serious threat for any entity using the affected products.

Vulnerability Summary

CVE ID: CVE-2025-48523
Severity: High (7.8 CVSS Score)
Attack Vector: Local
Privileges Required: None
User Interaction: None
Impact: Unauthorized contact addition can lead to local privilege escalation, potentially resulting in system compromise or data leakage.

Affected Products

Product | Affected Versions

[Product 1] | [All versions before patch]
[Product 2] | [All versions before patch]

How the Exploit Works

This exploit takes advantage of a logic error in the onCreate method of SelectAccountActivity.java. A malicious actor can manipulate the process to add contacts without the necessary permissions. This could allow them to escalate privileges locally, leading to potential system compromise or data leakage. And all of this can be done without the need for any user interaction.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited. This could be a sample Java code snippet, demonstrating how an attacker could manipulate the process to add contacts:

// Create a new account
Account newAccount = new Account("malicious_account", "com.example");
// Pass the new account to SelectAccountActivity
Intent intent = new Intent(context, SelectAccountActivity.class);
intent.putExtra("account", newAccount);
// Start the activity
context.startActivity(intent);

Mitigation Guidance

To mitigate this vulnerability, users are strongly advised to apply the vendor patch as soon as it is available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation measure to monitor for and block potential exploit attempts.
