CVE-2022-39912 is a medium-severity vulnerability affecting Samsung Mobile Devices running Android versions prior to Android T (Android 13). The vulnerability arises from improper handling of insufficient permissions or privileges within the setSecureFolderPolicy function of the PersonaManagerService. This service manages the Secure Folder feature, which is designed to isolate and protect sensitive data and applications on Samsung devices. Due to this flaw, a local attacker with access to the device can manipulate certain settings within the Secure Folder without having the appropriate permissions. This could potentially allow unauthorized changes to security policies or configurations within the Secure Folder environment. The vulnerability is classified under CWE-280, which relates to improper handling of insufficient permissions or privileges, indicating that the system does not adequately verify whether the caller has the necessary rights before allowing changes. There are no known exploits in the wild at this time, and no official patches have been linked or published yet. The vulnerability requires local access to the device, meaning the attacker must have physical or logical access to the device to exploit it. User interaction beyond local access is not explicitly required, but the attacker must be able to invoke the vulnerable function. The scope of impact is limited to Samsung Mobile Devices running affected Android versions, specifically those prior to Android 13. Since the Secure Folder is intended to protect sensitive user data and applications, unauthorized modification of its settings could undermine the confidentiality and integrity of the data stored within it. However, the vulnerability does not appear to allow direct remote exploitation or full device compromise.

For European organizations, the impact of CVE-2022-39912 primarily concerns the potential compromise of sensitive data stored within Secure Folders on Samsung Mobile Devices used by employees. Many enterprises use Secure Folder to segregate corporate data from personal data on mobile devices, so unauthorized changes to Secure Folder policies could lead to data leakage, unauthorized access to corporate applications, or weakening of security controls. This could result in exposure of confidential business information, intellectual property, or personal data protected under GDPR. The vulnerability requires local access, which limits the risk from remote attackers but raises concerns in scenarios involving lost or stolen devices, or insider threats. Organizations with mobile workforces relying on Samsung devices may face increased risk if devices are not adequately secured or if endpoint management policies do not enforce strong access controls. Additionally, since Secure Folder is a key component in Samsung's mobile security framework, exploitation could undermine trust in device security, potentially affecting compliance with data protection regulations. The absence of known exploits reduces immediate risk, but the vulnerability should be addressed promptly to prevent future abuse.

1. Enforce strict physical security and device access controls to prevent unauthorized local access to Samsung Mobile Devices. 2. Implement Mobile Device Management (MDM) solutions that can remotely lock, wipe, or enforce security policies on devices, including Secure Folder configurations. 3. Educate users on the importance of device PINs, biometrics, and screen lock mechanisms to reduce risk of unauthorized local access. 4. Monitor for updates from Samsung and Android vendors and apply patches or firmware updates as soon as they become available to address this vulnerability. 5. Restrict the use of Secure Folder for highly sensitive corporate data until a patch is applied, or consider alternative secure container solutions with verified security. 6. Audit and review Secure Folder settings regularly to detect unauthorized changes. 7. Limit the installation of untrusted applications that could attempt to exploit local vulnerabilities. 8. For organizations with Bring Your Own Device (BYOD) policies, enforce compliance checks to ensure devices are running patched software and have Secure Folder properly configured.
