The recent discovery of a critical security vulnerability (CVE-2022-39892) in Samsung Pass software has prompted the need for users to update their devices to ensure they're protected. Samsung Pass is a widely used biometric authentication platform for Samsung devices, and improper access control can have severe consequences. This post will provide an overview of the vulnerability, discuss potential exploit details, and offer solutions for users.

Vulnerability Overview

The CVE-2022-39892 vulnerability is related to improper access control in Samsung Pass versions prior to 4..05.1. This flaw allows attackers to gain unauthorized access to sensitive information via the "keep open" feature. The vulnerability exists due to a lack of proper authentication checks and can lead to unauthorized access, data leakage, and potential account takeover.

Please refer to the official CVE details for more information on this vulnerability.

Exploit Details

Although there is no available proof-of-concept (PoC) code or known exploits in the wild, an attacker can potentially exploit CVE-2022-39892 through the following steps:

1. The attacker gains physical access to the device or uses social engineering techniques to convince the user to enable the "keep open" feature (if it is not enabled already).

2. Once the feature is enabled, the attacker can exploit the improper access control vulnerability by accessing the device without authenticating themselves with Samsung Pass.

3. With unauthorized access to the device, the attacker can potentially access sensitive information such as stored passwords, contacts, messages, and other private data.

Here is a theoretical code snippet illustrating how an attacker might attempt to bypass the access control checks in Samsung Pass:

# Exploit code snippet
def bypass_access_control(samsung_pass):
    if samsung_pass.is_keep_open_enabled():
        print("Keep Open feature is disabled")

# Usage
device = SamsungDevice()
samsung_pass = device.get_samsung_pass()

Please note that this code snippet is for educational purposes only and should not be used to exploit the vulnerability.

Update your Samsung Pass software to version 4..05.1 or later.

2. Disable the "keep open" feature in your Samsung Pass settings to reduce the risk of unauthorized access.

3. Use device security best practices, such as setting strong, unique passwords for your devices and accounts, and keeping your software up-to-date.


With proper understanding and security measures, users can tackle the CVE-2022-39892 vulnerability in Samsung Pass. It is crucial to update your Samsung Pass software and follow recommended steps to ensure the safety of your devices and sensitive data. Stay vigilant and stay safe!
