CVE-2022-3684
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 · uneditedA vulnerability exists in a SDM600 endpoint. An attacker could exploit this vulnerability by running multiple parallel requests, the SDM600 web services become busy rendering the application unresponsive.

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 · moderate confidenceThis is a denial of service (DoS) vulnerability in Hitachi Energy SDM600 web services. An attacker can exploit the endpoint by sending multiple parallel requests, causing the web services to become overwhelmed and unresponsive. The vulnerability stems from insufficient handling of concurrent requests at the application layer, allowing resource exhaustion through parallel request attacks.

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.
-
Identify SDM600 software versionLocate the installed version of Hitachi Energy SDM600 in the system information, about page, or product documentation. This is typically visible in the web interface login page, system settings, or installed programs list.Affected if The installed version is 1.0 or higher but lower than 1.2.23000.291
-
Confirm web services are enabledAccess the SDM600 web interface and verify that web services (REST API, SOAP endpoints, or similar) are enabled in the configuration settings.Affected if Web services are enabled and accessible on the network
-
Check network exposureReview firewall rules, network ACLs, or access control lists to determine if the SDM600 web services endpoint is reachable from network segments outside the trusted zone.Affected if The web services are exposed to untrusted networks or the internet
-
Verify concurrent request handlingIf you have access to logs or monitoring tools, check for any existing evidence of service degradation, timeouts, or failures under normal load conditions.Affected if The system shows signs of instability or unavailability under concurrent request loads
-
Review current rate limiting configurationInspect the web services configuration for any rate limiting, throttling, or request queuing settings that may be currently applied.Affected if No rate limiting or throttling mechanisms are configured for the web services endpoint
A user is affected if SDM600 version is 1.0 through 1.2.23000.290 (inclusive) AND web services are enabled and accessible.
Generated from the published advisory. Verify against your own configuration.
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 · scoped1.2.23000.291
Upgrade to SDM600 version 1.2 FP3 HF4 (Build Nr. 1.2.23000.291) or later. As an interim measure, implement rate limiting on the web services endpoint and restrict network access to the service.
1.2 FP3 HF4 (Build Nr. 1.2.23000.291) or later
- 1. Identify the current installed version of SDM600 by accessing the device or checking system documentation.
- 2. Verify if the current version is below Build Nr. 1.2.23000.291 (versions prior to 1.2 FP3 HF4).
- 3. Contact ABB/Hitachi Energy technical support to obtain the upgrade package for version 1.2 FP3 HF4 (Build Nr. 1.2.23000.291) or later.
- 4. Follow the vendor's official upgrade procedure to apply the firmware/software update.
- 5. After upgrade, verify the new version is 1.2.23000.291 or higher and confirm the web services are functioning normally.
