CVE-2023-46711

Password recovery via hard-coded cryptographic key

Published Dec 26, 2023 · Updated Sep 12, 2024

Use of a hard-coded cryptographic key in BUFFALO INC. VR-S1000 firmware 2.37 and earlier allows attackers to recover a user's password. Published advisories do not identify the key's storage location, the protected password data, or the cryptographic operation that exposes it. Physical access to the appliance is required, and the documented consequence is limited to disclosure of one product user's password.
