CVE-2023-1995Network attack vector

Undetected data modification via omitted audit records

Published Aug 29, 2023 · Updated Sep 30, 2024

Insufficient logging in Hitachi HiRDB products allows remote authenticated users to modify data without complete audit records. Some audit records are not generated, but Hitachi has not disclosed the responsible component, omitted event classes, or faulty logging operation. Exploitation requires network access, low privileges, and unspecified high-complexity conditions; the bounded consequence is loss of audit integrity.
