CVE-2023-5808
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSMU versions prior to 14.8.7825.01 are susceptible to unintended information disclosure, through URL manipulation. Authenticated users in a Storage administrative role are able to access HNAS configuration backup and diagnostic data, that would normally be barred to that specific administrative role.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is an authentication-based authorization bypass in the Storage Management Utility (SMU). Authenticated users with a Storage administrative role can manipulate URLs to access HNAS configuration backup and diagnostic data that should be restricted to higher-privileged administrative roles. The vulnerability allows unintended information disclosure through improper access control enforcement in URL handling.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm HNAS Storage Management Utility is runningIdentify if the Hitachi Network Attached Storage (HNAS) system with Storage Management Utility (SMU) is present in the environment. Look for processes or services related to SMU or HNAS management interfaces.Affected if SMU is not installed or not in use, the system is not affected by this specific vulnerability.
-
Locate the installed SMU versionAccess the SMU administrative interface or use system commands to retrieve the Storage Management Utility version number. Typically found in system information, about pages, or via CLI commands specific to HNAS management.Affected if The version cannot be determined, making it impossible to assess vulnerability status.
-
Compare installed version against affected rangeTake the discovered SMU version and compare it to the affected range: all versions <= 14.8.7825.01 are vulnerable.Affected if The installed version is 14.8.7825.01 or earlier. Versions after 14.8.7825.01 are not affected.
-
Verify administrative role assignmentsReview user accounts and their assigned roles within the SMU. Specifically identify users granted Storage administrative roles versus higher-privileged administrative roles.Affected if Users with Storage administrative role exist and can access SMU - combined with a vulnerable version, this creates the bypass condition.
The environment is affected if SMU is running version 14.8.7825.01 or earlier and users with Storage administrative role have URL access that should be restricted to higher-privileged roles.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade SMU to version 14.8.7825.01 or later to obtain the fix for this authorization bypass vulnerability.
14.8.7825.01 or later
- Identify the current SMU (Storage Management Unit) version running on the Hitachi HNAS system
- Download version 14.8.7825.01 or later from Hitachi Vantara support portal (knowledge.hitachivantara.com)
- Plan maintenance window as upgrade may require system downtime
- Follow Hitachi Vantara upgrade procedures for SMU to apply the new version
- After upgrade, verify the SMU version has been updated to 14.8.7825.01 or later
- Test that users in Storage administrative role can no longer access HNAS configuration backup and diagnostic data through URL manipulation
