Improper Certificate Validation

CVE-2025-32407

Medium
5.9/10

Summary

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 NOTE: This vulnerability is in an end-of-life product that is no longer maintained by the vendor.

CWE-295 - Improper Certificate Validation

The authenticity component of a web system stems from the ability to validate “Digital certificates”, which (i) establish trust between two or more entities sharing data over a network; (ii) ensure data at rest and transit is secure from unauthorized access; and (iii) check the identity of the actors that interact with the system. An application with absent or ineffective certificate validation mechanisms allows malicious users, impersonating trusted hosts, to manipulate the communication path between the client and the host, resulting in unauthorized access to data and to the application’s internal environment, and potentially enabling man-in-the-middle attacks.
