This vulnerability allows local attackers to disclose sensitive information on affected installations of Samsung Knox 1.2.02.39 on Samsung Galaxy S9 build G9600ZHS3ARL1 Secure Folder. An attacker must first obtain physical access to the device in order to exploit this vulnerability. The specific flaws exists within the the handling of the lock screen for Secure Folder. The issue results from the lack of proper validation that a user has correctly authenticated. An attacker can leverage this vulnerability to disclose the contents of the secure container. Was ZDI-CAN-7381.

Samsung KNOX 1.0 uses a weak eCryptFS Key generation algorithm, which makes it easier for local users to obtain sensitive information by leveraging knowledge of the TIMA key and a brute-force attack.

ClipboardDataMgr in Samsung KNOX 1.0.0 and 2.3.0 does not properly check the caller, which allows local users to read KNOX clipboard data via a crafted application.

Samsung KNOX 1.0.0 uses the shared certificate on Android, which allows local users to conduct man-in-the-middle attacks as demonstrated by installing a certificate and running a VPN service.
