CVE-2023-30722

Local code execution via bc_tui protection failure

Published Sep 6, 2023 · Updated Sep 26, 2024

Protection-mechanism failure in Samsung Blockchain Keystore before 1.3.13.5 allows local users to execute arbitrary code. The bc_tui trustlet applies an inadequate protection mechanism to attacker-controlled input, but Samsung has not disclosed the failed check or input format. Exploitation requires low-privileged local access to a supported Galaxy device and yields code execution through the security-sensitive trustlet, with no user interaction.
