CVE-2025-58488: SmartTouchCall Information Disclosure Flaw

CVE-2025-58488 Overview

CVE-2025-58488 is a medium-severity vulnerability affecting Samsung SmartTouchCall application prior to version 1.0.1.1. The vulnerability stems from improper verification of the source of a communication channel, which allows remote attackers to access sensitive information. Notably, user interaction is required to trigger this vulnerability, which somewhat limits the attack surface but does not eliminate the risk entirely.

This vulnerability falls under the category of Improper Access Control and Information Disclosure, where the application fails to properly validate the origin of incoming communications before processing them. This oversight can be exploited by malicious actors to extract sensitive data from affected devices.

Critical Impact

Remote attackers can access sensitive information on affected Samsung SmartTouchCall installations. While user interaction is required, successful exploitation could lead to unauthorized disclosure of confidential data with high confidentiality impact.

Affected Products

• Samsung SmartTouchCall versions prior to 1.0.1.1
• Samsung mobile devices with SmartTouchCall application installed

Technical Details for CVE-2025-58488

Vulnerability Analysis

The vulnerability carries a CVSS 3.1 base score of 4.5 (Medium severity) with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:N/A:N.

Breaking down the CVSS metrics:

• Attack Vector (AV:N): Network-based attack, meaning exploitation can occur remotely
• Attack Complexity (AC:L): Low complexity required to execute the attack
• Privileges Required (PR:H): High privileges are needed by the attacker
• User Interaction (UI:R): User interaction is required for successful exploitation
• Scope (S:U): The vulnerability scope remains unchanged
• Confidentiality Impact (C:H): High impact on confidentiality of data
• Integrity Impact (I:N): No impact on data integrity
• Availability Impact (A:N): No impact on system availability

The EPSS (Exploit Prediction Scoring System) score is 0.038% with a percentile of 11.28 as of 2025-12-16, indicating a relatively low probability of exploitation in the wild.

Root Cause

The root cause of this vulnerability lies in the improper verification of the source of a communication channel within the SmartTouchCall application. The application fails to adequately validate the authenticity and origin of incoming communications before processing them, creating an opportunity for remote attackers to spoof or inject malicious requests.

This type of vulnerability typically occurs when applications:

• Do not implement proper origin validation for inter-process communications
• Accept data from untrusted sources without verification
• Lack appropriate security controls for validating communication channel authenticity

Attack Vector

The attack vector for CVE-2025-58488 is network-based, allowing remote exploitation. An attacker could craft malicious communications that appear to originate from a legitimate source to trick the SmartTouchCall application into processing unauthorized requests.

The attack scenario typically involves:

1. The attacker identifies a target device running a vulnerable version of SmartTouchCall
2. The attacker crafts a malicious communication that bypasses the source verification mechanism
3. The victim user performs an action that triggers the vulnerability (user interaction required)
4. The application processes the malicious request, exposing sensitive information to the attacker

Since no verified code examples are available for this vulnerability, technical details about the specific exploitation mechanism can be found in the Samsung Mobile Security advisory referenced below.

Detection Methods for CVE-2025-58488

Indicators of Compromise

• Unusual network traffic patterns from the SmartTouchCall application
• Unexpected data access or exfiltration attempts from affected mobile devices
• Anomalous inter-process communication behavior in SmartTouchCall logs

Detection Strategies

Organizations and individuals should implement the following detection strategies:

1. Application Version Monitoring: Regularly audit installed application versions to identify devices running SmartTouchCall versions prior to 1.0.1.1

2. Network Traffic Analysis: Monitor network traffic for suspicious communication patterns originating from or targeting the SmartTouchCall application

3. Mobile Device Management (MDM): Leverage MDM solutions to track application versions and enforce update policies across managed devices

4. Behavioral Analysis: Implement behavioral monitoring to detect unusual application behavior that may indicate exploitation attempts

Monitoring Recommendations

Security teams should consider the following monitoring approaches:

• Enable detailed logging for SmartTouchCall application activities where possible
• Configure alerts for any detected attempts to access sensitive information through abnormal channels
• Implement network-level monitoring for communications involving the SmartTouchCall application
• Regularly review Samsung Mobile Security advisories for additional indicators and updates

How to Mitigate CVE-2025-58488

Immediate Actions Required

• Update SmartTouchCall to version 1.0.1.1 or later immediately
• Review and audit any sensitive data that may have been accessible through the vulnerable application
• Implement network segmentation to limit potential exposure of affected devices
• Enable automatic updates for Samsung applications to receive security patches promptly

Patch Information

Samsung has addressed this vulnerability in SmartTouchCall version 1.0.1.1. Users should update to this version or later to remediate the vulnerability. The security advisory is available at Samsung Mobile Security's website:

• Advisory URL: https://security.samsungmobile.com/serviceWeb.smsb?year=2025&month=12

Users can update the application through:

• Samsung Galaxy Store
• Device Settings → Software Update → Download and Install

Workarounds

If immediate patching is not possible, consider the following temporary mitigations:

1. Restrict Application Permissions: Review and limit the permissions granted to SmartTouchCall to reduce the scope of potential data exposure

2. Network Controls: Implement network-level controls to monitor and restrict suspicious communications to/from devices running the vulnerable application

3. User Awareness: Educate users about the requirement for user interaction and advise caution when interacting with unexpected communications or prompts within the application

4. Application Isolation: Where feasible, consider temporarily disabling or restricting the SmartTouchCall application until patching can be completed

It is strongly recommended to apply the official patch as the primary remediation strategy rather than relying solely on workarounds.
