CVE-2023-21484

Vulnerability

A improper access control vulnerability exists in Samsung AppLock prior to SMR May-2023 Release 1 [1]. The flaw resides in the AppLock component, allowing local attackers without proper permission to execute a privileged operation due to inadequate access controls.

Exploitation

An attacker must have local access to the device. No special authentication or user interaction is required beyond being a local user. The attacker can exploit the vulnerability by launching a specially crafted operation that bypasses the intended permission checks in AppLock.

Impact

Successful exploitation enables the attacker to execute a privileged operation, potentially leading to unauthorized access to protected apps or sensitive data, or other elevated actions on the device. The exact CIA outcome is not disclosed in the references but implies a breach of confidentiality and integrity for locked applications.

Mitigation

Samsung has released the fix in SMR May-2023 Release 1 [1]. Users should update their device via Samsung's security update mechanism. No workarounds are provided; the only mitigation is to apply the latest security patch.
