CVE-2025-58487 is a vulnerability classified under CWE-285 (Improper Authorization) affecting Samsung Account applications on Samsung mobile devices prior to version 15.5.01.1. The flaw allows a local attacker—who does not require prior privileges or user interaction—to launch arbitrary activities with the privileges of the Samsung Account app. This improper authorization means that the app fails to properly verify whether the requesting entity is authorized to perform certain actions, potentially enabling unauthorized execution of privileged operations. The vulnerability impacts availability (denial or disruption of service) but does not compromise confidentiality or integrity of data. The CVSS 3.1 base score is 4.0, reflecting low attack complexity but limited scope and impact. Exploitation requires local access to the device, which limits the attack surface to insiders or malware already present on the device. No known exploits have been reported in the wild, and no official patches have been linked yet, though the issue is publicly disclosed. The vulnerability could be leveraged to disrupt Samsung Account services or trigger unintended behaviors within the app, potentially affecting device usability or dependent services. Samsung Account is a core service for device management, cloud synchronization, and authentication on Samsung devices, so exploitation could have operational consequences for users and organizations relying on these services.

For European organizations, this vulnerability poses a risk primarily to availability of Samsung Account services on affected devices. Disruption could impact device management, cloud sync, and authentication workflows, potentially hindering employee productivity and access to corporate resources tied to Samsung Account credentials. Since exploitation requires local access, the threat is higher in environments where devices may be physically accessible by unauthorized personnel or where malware could gain local execution. Organizations with large deployments of Samsung mobile devices, especially those integrated with enterprise mobility management (EMM) solutions relying on Samsung Account, may experience operational interruptions. While confidentiality and integrity are not directly impacted, the availability issues could cascade into broader business process disruptions. The lack of known exploits reduces immediate risk, but the public disclosure means attackers could develop exploits over time. European entities with stringent data protection and operational continuity requirements should consider this vulnerability in their risk assessments.

1. Apply the official patch or update Samsung Account to version 15.5.01.1 or later as soon as it becomes available from Samsung. 2. Restrict local device access to trusted users only, enforcing strong physical security controls to prevent unauthorized local access. 3. Employ mobile device management (MDM) or enterprise mobility management (EMM) solutions to monitor and control app permissions and behaviors on Samsung devices. 4. Monitor device logs and Samsung Account activity for unusual or unauthorized activity that could indicate exploitation attempts. 5. Educate users on the risks of installing untrusted applications or granting local access to unknown parties, reducing the risk of local attacker presence. 6. Consider implementing endpoint detection and response (EDR) solutions on mobile devices to detect suspicious local activity. 7. Review and tighten Samsung Account related configurations and permissions to minimize privilege exposure. 8. Coordinate with Samsung support channels for timely updates and vulnerability advisories.
