CVE-2019-20580

Vulnerability

The vulnerability is present on Samsung mobile devices with P(9.0) (Android 9) software. The Motion photo player component fails to properly enforce Secure Folder boundaries, allowing images stored within the Secure Folder to be viewed without authentication. The issue is identified by Samsung ID SVE-2019-14653 and was disclosed in August 2019 [1].

Exploitation

An attacker with physical access to the device or who can launch the Motion photo player on an unlocked device does not require authentication to bypass the Secure Folder restriction. By triggering the Motion photo player in a way that accesses images from the Secure Folder, the attacker can view protected images without providing the Secure Folder PIN or biometric authentication.

Impact

Successful exploitation allows an attacker to view images that are intended to be protected by the Secure Folder feature, leading to unauthorized disclosure of private or sensitive images. The attacker does not gain persistent access or elevated privileges beyond the Media provider context, but does bypass a security boundary meant to segregate confidential data.

Mitigation

The vulnerability was fixed by Samsung through a security update. Users should ensure their device runs the latest firmware as provided via Samsung's security maintenance releases [1]. No workaround is available; the fix must be applied through the official update channel.
