Samsung Account Under Attack? Analyzing CVE-2025-58487

Overview

CVE-2025-58487 is a medium severity vulnerability affecting Samsung Account prior to version 15.5.01.1. This vulnerability stems from improper authorization, allowing a local attacker to potentially launch arbitrary activities with Samsung Account privileges. This means a malicious application or attacker with local access to a device could exploit this weakness to perform actions as the legitimate user.

Technical Details

The specific flaw lies in the way Samsung Account handles authorization checks when launching certain activities. Prior to version 15.5.01.1, these checks were insufficient, allowing a malicious application with the right intent and permissions to bypass the intended security measures. A local attacker could craft a specific intent that leverages this bypass, effectively impersonating the Samsung Account and performing unauthorized actions. The exact mechanism of the bypass is specific to the Samsung Account implementation.

CVSS Analysis

The Common Vulnerability Scoring System (CVSS) assigns a score of 4.0 to CVE-2025-58487, indicating a medium severity. The CVSS vector likely reflects the following characteristics:

• Attack Vector (AV): Local (L) – Requires local access to the device.
• Attack Complexity (AC): Low (L) – The vulnerability is relatively easy to exploit.
• Privileges Required (PR): None (N) – No special privileges are needed to exploit the vulnerability.
• User Interaction (UI): Required (R) – User interaction may be required to trigger the exploit (e.g., installing a malicious application).
• Scope (S): Unchanged (U) – An exploited vulnerability cannot affect resources beyond the security scope managed by the security authority of the vulnerable component.
• Confidentiality Impact (C): None (N) – No impact to confidentiality.
• Integrity Impact (I): Low (L) – There is limited modification of data integrity.
• Availability Impact (A): None (N) – No impact to availability.

Possible Impact

The impact of exploiting CVE-2025-58487 could include:

• Unauthorized access to Samsung Account features.
• Potential modification of Samsung Account settings.
• Triggering actions within other Samsung applications that rely on the account.
• Information disclosure (depending on the specific activity launched).

It’s important to note that the impact is limited by the capabilities of the Samsung Account and the privileges it possesses.

Mitigation or Patch Steps

The primary mitigation step is to update your Samsung Account application to version 15.5.01.1 or later. You can usually do this through the Samsung Galaxy Store or the Google Play Store. Regularly checking for and installing updates is a crucial part of maintaining the security of your device.

1. Check your Samsung Account version: Go to your device settings, find “Apps” or “Applications,” locate “Samsung Account,” and check the version number.
2. Update via Galaxy Store or Play Store: Open the Samsung Galaxy Store or Google Play Store and search for “Samsung Account.” If an update is available, install it.
3. Restart your device: After updating, restart your device to ensure the changes take effect.
