The vulnerability exist due to improper implementation of the authentication mechanism in Samsung Pass. By modifying some system files on an unlocked Android device, the attacker can bypass the authentication mechanism and get full access to the data stored on the device.
In order to exploit the vulnerability, a physical attacker needs to be physically close to an unlocked Android device, for example, in a hotel room or in a cafe.
The attacker needs to get access to the Android device and modify some system files. Then, the attacker needs to make sure that no one checks the device before the next day. For example, the attacker can put the Android device in a bag with some clothes. A next day when the attacker comes to an unlocked Android device, the attacker needs to have physical access to the Android device. The attacker needs to start the Android device and login to Samsung pass. After that, the attacker can start to access the data stored on the device. The data that can be accessed depends on the version of Samsung pass. The most common cases are accessing email and SMS data.
Vulnerability found on Samsung Pass 2017.6.23
1.Samsung Pass authentication mechanism has improper implementation by which attackers can bypass the authentication mechanism and get full access to the data stored on the device.
2.The attacker needs to be physically close to an unlocked Android device, for example, in a hotel room or in a cafe.
3.The attacker needs to modify some system files on an unlocked Android device, for example, modifying the counter value of sec_core_sysctl_max_threads in /system/bin/getprop with root permission.
4.The attacker needs to make sure that no one checks the device before the next day. For example, the attacker can put the Android device in a bag with some clothes. A next day when the attacker comes to an unlocked Android device, they need to have physical access to the Android device and start it up again.
5.After that, the attacker can start logging into Samsung pass and starting accessing data stored on the device like email and SMS data
##cve-2022-36852
The vulnerability exist due to improper implementation of the authentication mechanism in Samsung Pass.
By modifying some system files on an unlocked Android device, the attacker can bypass the authentication mechanism and get full access to the data stored on the device.
The attacker needs to start the Android device and login to Samsung pass. Then, when the victim tries to login to Samsung pass, it will ask for a password from a known number. If a code is received from that number, then it means that someone else is accessing the victim’s phone. In this case, Samsung Pass will automatically block further attacks because it has detected an unauthorized user attempting to log in.
Vulnerability summary
The vulnerability exists in the Samsung pass application. The attacker can bypass the authentication mechanism and get full access to the data stored on an Android device by modifying system files on the unlocked Android device. The Android device needs to be unlocked before someone can exploit this vulnerability in order to get access. An attacker needs to have physical access to a locked Android device and modify some system files. Then, the attacker needs to make sure that no one checks the device before the next day. For example, an attacker can put the Android device in a bag with some clothes or put it in a hotel room safe overnight. When someone comes for it next day, they will find their login credentials logged into Samsung Pass without authentication and have full access to all of their data.
A vulnerable version of Samsung Pass is 2.2.1 or earlier on devices running Android 4 or later.
Bug identification and root cause analysis
The vulnerability exists because of improper implementation of the authentication mechanism in Samsung Pass. The attacker needs to get access to an unlocked Android device and modify some system files. Then, the attacker needs to make sure that no one checks the device before the next day. For example, the attacker can put the Android device in a bag with some clothes. A next day when the attacker comes to an unlocked Android device, the attacker needs to have physical access to it.
After that, the attacker can start accessing data stored on it by logging into Samsung Pass. The data that can be accessed depends on which version of Samsung pass is used; however, most commonly email and SMS data is accessible.
The bug identification process starts with understanding what kind of information is stored on the target device and how vulnerable are these data to be exposed. Based on this information, an effective root cause analysis can be conducted.
B usting the Myths of Passwords
Passwords are a common method for securing sensitive data. But passwords aren't foolproof, and it's not always easy to determine if your password is strong enough. This is why hackers continue to devise more sophisticated ways to crack encrypted data.
One of the most popular methods is to use passcodes. Passcodes are better than passwords because they can be changed on a regular basis without compromising the security of your data. However, they're not as secure as biometric authentication mechanisms like fingerprints or facial recognition because they can be stolen through photos or video recordings.
Another technique that hackers use is brute force attack. In this type of attack, an attacker tries every possible combination of character until he finds one that works and thus gains access to your account. These attacks are often only effective with short passwords so consider using a stronger one like "password".
Another layer of protection you should consider implementing is two-factor authentication. For example, you might put in a code from your smartphone when logging in to your device. This makes it harder for hackers who get close enough to steal a password or passcode and use them later on during the same login session without having physical access to the device.
