CVE-2025-32407: n/a
Samsung Internet for Galaxy Watch version 5.0.9, available up until Samsung Galaxy Watch 3, does not properly validate TLS certificates, allowing for an attacker to impersonate any and all websites visited by the user. This is a critical misconfiguration in the way the browser validates the identity of the server. It negates the use of HTTPS as a secure channel, allowing for Man-in-the-Middle attacks, stealing sensitive information or modifying incoming and outgoing traffic. NOTE: This vulnerability is in an end-of-life product that is no longer maintained by the vendor.
AI Analysis
Technical Summary
CVE-2025-32407 is a vulnerability affecting Samsung Internet browser version 5.0.9 on Galaxy Watch devices up to the Galaxy Watch 3. The core issue is improper validation of TLS certificates by the browser, which undermines the fundamental security guarantees of HTTPS. TLS certificate validation is critical to ensure that the server a client connects to is authentic and trusted. Failure to properly validate certificates allows an attacker to impersonate any website the user attempts to visit, facilitating Man-in-the-Middle (MitM) attacks. Through such attacks, an adversary can intercept, modify, or steal sensitive information transmitted between the watch and the web server. This vulnerability is classified under CWE-295, which pertains to improper certificate validation. Notably, the affected product is end-of-life and no longer maintained by Samsung, meaning no official patches or updates are available to remediate this flaw. The CVSS v3.1 base score is 5.9 (medium severity), with the vector indicating network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and no availability impact (A:N). This suggests that while exploitation is possible remotely without authentication or user interaction, the attack complexity is high, and the primary impact is on confidentiality. There are no known exploits in the wild at this time. The vulnerability effectively negates the security benefits of HTTPS on the affected devices, exposing users to potential data theft and traffic manipulation when browsing the web via the vulnerable Samsung Internet browser on their Galaxy Watches.
Potential Impact
For European organizations, the impact of this vulnerability depends largely on the usage of Samsung Galaxy Watch devices within their workforce or user base. If employees or customers use affected Galaxy Watch models with the vulnerable browser for accessing corporate or sensitive web services, there is a risk of sensitive data exposure through MitM attacks, especially on untrusted networks such as public Wi-Fi. This could lead to leakage of authentication tokens, personal data, or confidential business information. Although the vulnerability does not affect data integrity or availability, the confidentiality breach could facilitate further attacks or espionage. The fact that the product is end-of-life and unpatched increases the risk for organizations that have not retired these devices. Additionally, given the wearable nature of the device, users may connect to various networks, increasing exposure to hostile environments. However, the high attack complexity and lack of known exploits somewhat reduce the immediate threat level. Still, organizations should consider this vulnerability in their risk assessments, particularly those with mobile or remote workforces relying on wearable technology for business communications or web access.
Mitigation Recommendations
Since the affected Samsung Internet browser version 5.0.9 on Galaxy Watch devices up to Galaxy Watch 3 is end-of-life and unpatched, mitigation options are limited. Organizations should: 1) Identify and inventory all Galaxy Watch devices in use, specifically those running the vulnerable browser version. 2) Retire or replace affected Galaxy Watch models with newer devices that receive security updates and do not have this vulnerability. 3) Disable or restrict use of the Samsung Internet browser on these devices, if possible, to prevent exposure. 4) Educate users about the risks of connecting to untrusted networks and encourage use of VPNs or secure network connections when accessing sensitive information. 5) Monitor network traffic for suspicious MitM activity, especially on networks frequently used by wearable devices. 6) Implement network-level protections such as DNS filtering and HTTPS inspection with caution, ensuring they do not interfere with legitimate TLS validation. 7) Consider deploying Mobile Device Management (MDM) solutions that can enforce security policies or restrict browser usage on wearable devices. These steps go beyond generic advice by focusing on device lifecycle management, user education, and network monitoring tailored to the unique context of wearable devices.
