CVE-2025-58481 is a vulnerability classified under CWE-284 (Improper Access Control) found in the MPRemoteService component of Samsung Mobile's MotionPhoto feature. The flaw exists in versions prior to 4.1.51 and allows a local attacker with limited privileges (PR:L) to start a privileged service, effectively escalating their permissions. The vulnerability requires local access and some user interaction (UI:R), but no network access, which limits remote exploitation but still poses a significant risk if an attacker gains physical or local access to the device. The CVSS 3.1 score of 7.3 reflects high severity, with impacts rated high on confidentiality, integrity, and availability (C:H/I:H/A:H). By exploiting this vulnerability, an attacker could execute privileged operations, potentially leading to full device compromise, unauthorized data access, or disruption of device functionality. No public exploits are known yet, but the vulnerability's nature suggests it could be leveraged in targeted attacks or by malicious insiders. Samsung's MotionPhoto is a feature integrated into their mobile devices, widely used in Europe, making the vulnerability relevant for a large user base. The lack of patch links indicates that fixes may still be pending or in deployment. Proper mitigation requires timely updates and restricting local device access to trusted users.

For European organizations, the vulnerability poses a significant risk especially in sectors where Samsung mobile devices are prevalent, such as telecommunications, government, and enterprise environments. Exploitation could lead to unauthorized privilege escalation on devices, enabling attackers to access sensitive corporate or personal data, manipulate device functions, or disrupt operations. This is particularly critical for organizations with Bring Your Own Device (BYOD) policies or those relying on Samsung devices for secure communications. The local access requirement limits mass exploitation but does not eliminate risk from insider threats or physical device theft. The high impact on confidentiality, integrity, and availability means that successful exploitation could result in data breaches, loss of trust, and operational downtime. Given the widespread use of Samsung devices in Europe, the vulnerability could affect a broad user base, increasing the potential attack surface.

1. Monitor Samsung's official security advisories and apply the MotionPhoto update to version 4.1.51 or later as soon as patches become available. 2. Enforce strict physical security controls to prevent unauthorized local access to devices, including device lock policies and secure storage. 3. Implement mobile device management (MDM) solutions to control application permissions and restrict installation of untrusted apps that could exploit local vulnerabilities. 4. Educate users about the risks of local privilege escalation and the importance of not granting unnecessary permissions or interacting with suspicious prompts. 5. For high-risk environments, consider disabling the MotionPhoto feature if feasible until patches are applied. 6. Regularly audit devices for signs of compromise or unusual service activity related to MPRemoteService. 7. Limit the number of users with local access privileges and enforce strong authentication mechanisms on devices.
