Overview
CVE-2025-58483 is a medium severity vulnerability affecting the Galaxy Store application for Galaxy Watch. Specifically, an improper export of Android application components within the Galaxy Store allows a local attacker to potentially install arbitrary applications on the device. This vulnerability exists in versions prior to 1.0.06.29.
Technical Details
The root cause of this vulnerability lies in the insufficient access control of exported components within the Galaxy Store application. Android applications can expose certain components (e.g., Activities, Services, Broadcast Receivers, Content Providers) for use by other applications. If these components are improperly exported without adequate permission checks, a malicious local application can leverage them to perform actions it would otherwise not be authorized to do.
In the case of CVE-2025-58483, an attacker can exploit the improperly exported component to bypass normal application installation procedures, effectively allowing them to install unapproved or malicious applications onto the Galaxy Watch through the Galaxy Store application. This bypass avoids standard security checks and user consent mechanisms.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns CVE-2025-58483 a score of 5.9 (Medium).
While the exploit requires local access, the potential impact is significant. The CVSS vector likely reflects the following:
- Attack Vector (AV): Local
- Attack Complexity (AC): High (potentially requiring specific knowledge of the component and how to interact with it)
- Privileges Required (PR): Low (attacker likely needs a low-privileged application installed)
- User Interaction (UI): None
- Scope (S): Unchanged
- Confidentiality Impact (C): None
- Integrity Impact (I): High (arbitrary application installation modifies the system)
- Availability Impact (A): None
Possible Impact
Successful exploitation of this vulnerability could lead to several negative consequences:
- Malware Installation: Attackers could install malicious applications designed to steal data, track user activity, or cause other forms of harm.
- Privilege Escalation: A malicious application installed through this vulnerability could potentially gain higher privileges on the device.
- Data Theft: Installed applications could exfiltrate sensitive data stored on the Galaxy Watch or accessible through connected services.
- Denial of Service: Malicious applications could consume resources or cause the device to malfunction, leading to a denial of service.
Mitigation and Patch Steps
The primary mitigation is to update the Galaxy Store application on your Galaxy Watch to version 1.0.06.29 or later. Samsung has addressed this vulnerability in subsequent releases. To update:
- Open the Galaxy Store application on your Galaxy Watch.
- Navigate to the “Updates” section.
- Check if an update is available for the Galaxy Store application.
- If an update is available, install it.
Users should also exercise caution when installing applications from unknown or untrusted sources, even if they appear to be from the Galaxy Store.
