CVE-2021-42066Network attack vector

Database password disclosure via cleartext network transmission

Published Dec 14, 2021 · Updated Aug 4, 2024

Cleartext credential storage in SAP Business One before 10.0 allows remote authenticated users with admin rights to read the database password. An undisclosed administrative function sends the database password across the network in plaintext instead of protecting it with encryption. Exploitation requires administrator privileges and in-depth application knowledge; the demonstrated consequence is disclosure of a reusable database credential.
