CVE-2025-58482: Samsung Motionphoto Privilege Escalation

CVE-2025-58482 Overview

CVE-2025-58482 is a high-severity improper access control vulnerability affecting the MPLocalService component of Samsung MotionPhoto application prior to version 4.1.51. This vulnerability allows local attackers to start privileged services, potentially leading to privilege escalation and compromise of device integrity.

The vulnerability stems from insufficient access control mechanisms in the MPLocalService component, which fails to properly validate the caller's permissions before executing privileged operations. With a CVSS v3.1 score of 7.3 (HIGH), this vulnerability presents significant risk to affected Samsung mobile devices.

Critical Impact

Local attackers can exploit improper access controls in MPLocalService to start privileged services, potentially achieving elevated system access with high impact on confidentiality, integrity, and availability.

Affected Products

• Samsung MotionPhoto versions prior to 4.1.51
• Samsung mobile devices with MotionPhoto application installed
• All Samsung devices running vulnerable MotionPhoto versions

Technical Details for CVE-2025-58482

Vulnerability Analysis

The vulnerability exists in the MPLocalService component of Samsung MotionPhoto application. The CVSS vector CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H indicates:

• Attack Vector (AV:L): Local access is required to exploit this vulnerability
• Attack Complexity (AC:L): Low complexity to execute the attack
• Privileges Required (PR:L): Low-level privileges are needed
• User Interaction (UI:R): Some user interaction is required
• Scope (S:U): The vulnerability is contained within the affected component
• Impact: High impact on Confidentiality, Integrity, and Availability

The Exploit Prediction Scoring System (EPSS) rates this vulnerability at 0.012% probability of exploitation in the wild, placing it in the 1.321 percentile of all scored vulnerabilities.

Root Cause

The root cause of this vulnerability is improper access control in the MPLocalService service component. The service fails to adequately verify the permissions and identity of calling applications before allowing them to invoke privileged operations. This design flaw enables malicious applications with limited privileges to interact with MPLocalService and trigger privileged service execution.

Android services typically should implement robust permission checks using mechanisms such as signature-level permissions, UID verification, or explicit permission declarations in the manifest. The absence or inadequate implementation of these controls in MPLocalService creates the exploitation opportunity.

Attack Vector

An attacker with local access to a Samsung device can exploit this vulnerability by:

1. Installing a malicious application on the target device
2. The malicious application invokes the vulnerable MPLocalService through inter-process communication (IPC)
3. Due to improper access controls, the service accepts the request without proper authorization validation
4. The attacker's request triggers the execution of a privileged service
5. The attacker gains elevated privileges on the device

The attack requires user interaction (UI:R), suggesting the victim may need to install or launch the malicious application. Once executed, the vulnerability can compromise device confidentiality, integrity, and availability with high severity.

Detection Methods for CVE-2025-58482

Indicators of Compromise

• Unexpected IPC calls to MPLocalService from unauthorized applications
• Privileged service execution initiated by non-system applications
• Anomalous process spawning with elevated privileges originating from MotionPhoto components
• Unusual permission escalation events on Samsung devices

Detection Strategies

Application-Level Monitoring:
Monitor for applications attempting to bind to or communicate with MPLocalService that do not have legitimate need to access MotionPhoto functionality. Security solutions should flag any non-Samsung applications attempting IPC with this service.

Process Behavior Analysis:
Track service execution patterns on Samsung devices. Any privileged service launches that originate from unexpected sources or follow unusual execution chains should be investigated.

Log Analysis:
Review Android system logs for service binding attempts to MPLocalService and correlate with the source application's permissions and signature status.

Monitoring Recommendations

Organizations should implement mobile device management (MDM) solutions that can:

• Inventory installed MotionPhoto versions across managed devices
• Alert on applications attempting suspicious service interactions
• Monitor for privilege escalation indicators on Samsung devices
• Track application installation patterns for potentially malicious apps

SentinelOne Singularity Mobile provides behavioral analysis capabilities that can detect exploitation attempts targeting Android service vulnerabilities, including unauthorized privilege escalation through improper access control bypasses.

How to Mitigate CVE-2025-58482

Immediate Actions Required

• Update Samsung MotionPhoto to version 4.1.51 or later immediately
• Review installed applications for potentially malicious software
• Enable automatic updates for Samsung applications via Galaxy Store
• Implement mobile device management policies restricting app installations from unknown sources

Patch Information

Samsung has addressed this vulnerability in MotionPhoto version 4.1.51. The security update is documented in Samsung's December 2025 security bulletin available at:

• Samsung Mobile Security Advisory - December 2025

Users should update their MotionPhoto application through the Galaxy Store or Samsung application update mechanisms. Enterprise administrators should prioritize deployment of this update across managed Samsung device fleets.

Workarounds

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

• Disable or force-stop the MotionPhoto application until the update can be applied
• Restrict application installation to trusted sources only (Galaxy Store, Google Play Store)
• Implement application whitelisting through MDM solutions
• Monitor device logs for suspicious service access patterns
• Consider temporarily removing the MotionPhoto application from high-risk devices

Organizations should prioritize patching as the primary mitigation strategy, as workarounds may impact functionality and do not fully address the underlying vulnerability.
