HiRDB Server: Insufficient Logging

CVE-2023-1995 is a high-severity insufficient logging vulnerability in HiRDB Server from Hitachi, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 09-60, 09-60-39, 09-65-23 as the first without the flaw, so updating HiRDB Server to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.46% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update HiRDB Server to 09-60 or 09-60-39 or 09-65-23 or 09-66-17, whichever matches your release line, or a later version.
  2. Update HiRDB Server With Addtional Function to 09-60 or 09-60-2M or 09-65-/W or 09-66-/Q, whichever matches your release line, or a later version.
  3. Update HiRDB Structured Data Access Facility to 09-60 or 09-60-39 or 10-03-12 or 10-04-06, whichever matches your release line, or a later version.
  4. Read the advisory on hitachi.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Insufficient Logging

When a security-critical event occurs, the product either does not record the event or omits important details about the event when logging it.

How developers prevent this class of flaw

  • Use a centralized logging mechanism that supports multiple levels of detail.
  • Ensure that all security-related successes and failures can be logged. When storing data in the cloud (e.g., AWS S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to enable and capture detailed logging information.
  • Be sure to set the level of logging appropriately in a production environment. Sufficient data should be logged to enable system administrators to detect attacks, diagnose errors, and recover from attacks. At the same time, logging too much data (CWE-779) can cause the same problems, including unexpected costs when using a cloud environment.
