CVE-2021-45447Network attack vector

Database credential disclosure via cleartext Data Lineage transmission

Published Nov 2, 2022 · Updated May 2, 2025

Cleartext transmission in Pentaho Business Analytics Server before 9.3.0.0, 9.2.0.2, or 8.3.0.25 allows attackers to capture database passwords. When Data Lineage is enabled, the server sends database credentials without transport encryption, exposing passwords to packet capture. Access to traffic on the server's network path is required; captured credentials enable unauthorized access to the associated database.
