CVE-2025-20961: CWE-280: Improper Handling of Insufficient Permissions or Privileges in Samsung Mobile Samsung Mobile Devices
Improper handling of insufficient permission or privileges in sepunion service prior to SMR May-2025 Release 1 allows local privileged attackers to access files with system privilege.
AI Analysis
Technical Summary
CVE-2025-20961 is a medium-severity vulnerability affecting Samsung Mobile Devices, specifically related to improper handling of insufficient permissions or privileges in the 'sepunion' service prior to the SMR (Security Maintenance Release) May-2025 Release 1. The vulnerability is categorized under CWE-280, which involves improper handling of insufficient permissions or privileges. This flaw allows a local attacker with limited privileges to escalate their access and read files with system-level privileges. The vulnerability requires local access to the device and some user interaction, as indicated by the CVSS vector (AV:L/AC:L/PR:N/UI:R). The vulnerability impacts confidentiality by allowing unauthorized access to sensitive files, but does not affect integrity or availability. The vulnerability does not require prior authentication but does require user interaction, which may limit exploitation scenarios. No known exploits are currently reported in the wild, and no patches or mitigation links are provided yet. The vulnerability was reserved in November 2024 and published in May 2025, indicating recent discovery and disclosure. The technical root cause is improper permission checks in the sepunion service, which is a component of Samsung Mobile devices, potentially related to system-level file access controls. Attackers exploiting this vulnerability could gain access to sensitive system files, potentially leading to further privilege escalation or information disclosure.
Potential Impact
For European organizations, the impact of CVE-2025-20961 could be significant, especially for enterprises and government agencies that rely on Samsung Mobile devices for secure communications and data handling. Unauthorized access to system files could lead to leakage of sensitive corporate or personal data, undermining confidentiality and potentially violating GDPR requirements. Although the vulnerability requires local access and user interaction, the risk remains for scenarios such as lost or stolen devices, insider threats, or social engineering attacks that trick users into executing malicious actions. The inability to maintain confidentiality could damage organizational reputation and lead to regulatory penalties. Additionally, attackers could leverage this vulnerability as a stepping stone for further attacks on the device or connected networks. The medium severity rating suggests a moderate risk, but the widespread use of Samsung Mobile devices in Europe increases the potential attack surface. Organizations with mobile device management (MDM) solutions and strict endpoint security policies may mitigate some risks, but awareness and timely patching remain critical.
Mitigation Recommendations
Given the lack of an official patch link, European organizations should implement several practical mitigations: 1) Enforce strict physical security controls to prevent unauthorized local access to devices. 2) Educate users on the risks of social engineering and the importance of not interacting with suspicious prompts or applications that could trigger the vulnerability. 3) Utilize Mobile Device Management (MDM) solutions to monitor device integrity and restrict installation of untrusted applications. 4) Apply the SMR May-2025 Release 1 update as soon as it becomes available to remediate the vulnerability. 5) Implement device encryption and strong authentication mechanisms to reduce the risk of unauthorized access. 6) Conduct regular audits of device permissions and installed services to detect anomalies related to the sepunion service. 7) Limit the use of Samsung Mobile devices for handling highly sensitive information until patches are applied. These targeted measures go beyond generic advice by focusing on the specific nature of the vulnerability and its exploitation requirements.
