CVE-2025-21065

Vulnerability

Overview CVE-2025-21065 is an improper input validation vulnerability in Samsung's Retail Mode, a feature designed for in-store demonstration devices. The issue exists in versions prior to 5.59.11, where insufficient validation of user-supplied input allows an attacker to bypass security controls [1].

Exploitation

Conditions An attacker must have physical or local access to a device running a vulnerable version of Retail Mode. No network access or additional authentication is required beyond being able to interact with the Retail Mode interface. The vulnerability is considered self-exploitable, meaning the attacker can exploit it directly on their own device [1].

Impact

Successful exploitation enables the attacker to execute privileged commands, effectively escalating their privileges to a level that bypasses the intended restrictions of Retail Mode. This could allow unauthorized modifications, installation of applications, or other administrative actions on the device [1].

Mitigation

Samsung has addressed the vulnerability in Retail Mode version 5.59.11. Users should update their devices to the latest version via Samsung's security update process. No workarounds have been reported [1].
