CVE-2025-20953: CWE-284: Improper Access Control in Samsung Mobile Samsung Mobile Devices
Improper access control in SmartManagerCN prior to SMR May-2025 Release 1 allows local attackers to launch activities within SmartManagerCN.
AI Analysis
Technical Summary
CVE-2025-20953 is a medium-severity vulnerability identified in Samsung Mobile Devices, specifically involving the SmartManagerCN component. The vulnerability is classified under CWE-284, which pertains to improper access control. This flaw allows local attackers to launch activities within the SmartManagerCN application without requiring any privileges or user interaction. The vulnerability exists in versions of Samsung Mobile Devices prior to the SMR (Security Maintenance Release) May-2025 Release 1 update. The CVSS 3.1 base score is 5.1, reflecting a medium severity level, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and low impact on confidentiality and integrity (C:L/I:L), with no impact on availability (A:N). Essentially, an attacker with local access to the device can exploit this vulnerability to initiate activities within SmartManagerCN, potentially leading to unauthorized actions or information disclosure within that component. However, the vulnerability does not allow remote exploitation, does not require elevated privileges, and does not impact system availability. There are no known exploits in the wild at the time of publication, and no patch links have been provided yet, indicating that remediation may be pending or forthcoming in the May-2025 SMR update.
Potential Impact
For European organizations, the impact of CVE-2025-20953 depends largely on the deployment of Samsung Mobile Devices within their environment and the sensitivity of data or operations managed via SmartManagerCN. Since the vulnerability allows local attackers to launch activities within SmartManagerCN without privileges or user interaction, it could facilitate unauthorized access to device management functions or sensitive information handled by this component. This could lead to limited confidentiality and integrity breaches, such as unauthorized configuration changes or data leaks. However, the requirement for local access significantly reduces the risk from remote attackers, focusing the threat on insider threats or scenarios where physical or local access to devices is possible. For organizations with strict mobile device management policies, especially those using Samsung devices extensively, this vulnerability could be exploited to bypass certain controls or gain unauthorized insights into device management operations. The absence of availability impact means service disruption is unlikely. Overall, the threat is moderate but should be addressed promptly to prevent potential lateral movement or escalation within corporate environments.
Mitigation Recommendations
To mitigate CVE-2025-20953 effectively, European organizations should: 1) Ensure that all Samsung Mobile Devices are updated to the SMR May-2025 Release 1 or later as soon as the patch becomes available. 2) Enforce strict physical security controls to prevent unauthorized local access to mobile devices, including secure storage and use of device locks with strong authentication mechanisms. 3) Implement mobile device management (MDM) solutions that monitor and restrict the use of device management applications like SmartManagerCN, limiting the ability of unauthorized users to interact with these components. 4) Conduct regular audits of device configurations and logs to detect any unusual activity within SmartManagerCN or related management apps. 5) Educate employees on the risks of leaving devices unattended or lending them to unauthorized individuals, reducing the risk of local exploitation. 6) Consider deploying endpoint detection and response (EDR) tools capable of identifying suspicious local activity on mobile devices. These steps go beyond generic patching advice by emphasizing physical security, monitoring, and user awareness tailored to the nature of this local access vulnerability.
