CVE-2025-58483 is a vulnerability classified under CWE-926 (Improper Export of Android Application Components) that affects the Galaxy Store application designed for Samsung Galaxy Watch devices. The flaw arises from the improper export configuration of certain Android components within the Galaxy Store app, which allows a local attacker to exploit these exported components to install arbitrary applications without requiring any privileges or user interaction. This means that if an attacker gains local access to the Galaxy Watch or a connected device, they can leverage this vulnerability to silently install malicious or unauthorized applications through the Galaxy Store interface. The vulnerability is present in versions of the Galaxy Store app prior to 1.0.06.29. The CVSS v3.1 base score of 5.9 reflects a medium severity level, with attack vector classified as local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impacts on confidentiality, integrity, and availability rated as low (C:L, I:L, A:L). No public exploits have been reported to date, but the vulnerability poses a risk especially in scenarios where devices are physically accessible or compromised through other means. The improper export of components is a common Android security issue where components such as activities, services, or broadcast receivers are unintentionally exposed to other apps or processes, enabling unauthorized interactions. This vulnerability could be leveraged to bypass normal app installation restrictions on the Galaxy Watch platform, potentially leading to the installation of malicious applications that could further compromise device security or user data.

For European organizations, the impact of CVE-2025-58483 primarily concerns the security of Samsung Galaxy Watch devices used within corporate environments. The ability for a local attacker to install arbitrary applications without user consent or privileges could lead to unauthorized access to sensitive corporate data, espionage, or lateral movement within enterprise networks if the watch is paired with corporate smartphones or systems. Confidentiality is at risk due to potential data leakage from malicious apps; integrity could be compromised if unauthorized apps alter device or data behavior; availability might be affected if malicious apps disrupt normal device functions. The local attack vector limits the threat to scenarios where an attacker has physical access or has compromised the device through other means, such as malware on a paired smartphone. However, given the increasing use of wearable devices in business contexts, including health monitoring and secure communications, this vulnerability could be exploited to undermine organizational security policies. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks. Organizations in sectors with high security requirements, such as finance, government, and critical infrastructure, should be particularly vigilant.

To mitigate the risks posed by CVE-2025-58483, European organizations should take the following specific actions: 1) Ensure all Samsung Galaxy Watch devices are updated to Galaxy Store version 1.0.06.29 or later, where the vulnerability is patched. 2) Implement strict physical security controls to prevent unauthorized local access to wearable devices, including secure storage and device lock policies. 3) Enforce endpoint management policies that monitor and restrict app installations on wearable devices, integrating Galaxy Watches into Mobile Device Management (MDM) or Enterprise Mobility Management (EMM) solutions where possible. 4) Educate users about the risks of connecting Galaxy Watches to untrusted devices or networks and the importance of reporting lost or stolen devices immediately. 5) Monitor network and device logs for unusual app installation activities or anomalies related to Galaxy Store usage. 6) Collaborate with Samsung support channels to stay informed about further updates or advisories related to Galaxy Watch security. 7) Consider disabling or limiting Galaxy Store functionality on corporate devices if not required, to reduce the attack surface. These measures go beyond generic advice by focusing on device-specific controls and organizational policies tailored to wearable technology security.
