# HiRDB: origin validation flaw in database server versions 9 and 10

HiRDB, a Hitachi relational database server, has an origin validation error that the sources do not detail further. The NVD entry rates it high (CVSS 7.5), which suggests a remote attacker could reach the server and affect data or service.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed HiRDB Server version against the affected ranges: Version 10 before `10-12-01`, Version 9 from `09-00` through `09-66-22`, and the 9(32) and Additional Function variants listed in the NVD entry.
- unknown for other checks: the sources do not say which configuration or port exposes the flaw.

## Fix

- Move HiRDB Server Version 10 to `10-12-01` or later, per the vendor advisory.
- unknown for Version 9 fixes: the sources do not name a fixed Version 9 release.
