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 · unedited
SD-330AC and AMC Manager provided by silex technology, Inc. contain an improper neutralization of CRLF sequences ('CRLF Injection') vulnerability. Processing some crafted configuration data may lead to arbitrary entries injected to the system configuration.

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 confidence

The SD-330AC device and AMC Manager software contain a CRLF Injection vulnerability in their configuration data processing. Attackers can inject Carriage Return Line Feed (CRLF) sequences into configuration data, allowing arbitrary entries to be added to the system configuration. This improper neutralization of special characters enables manipulation of configuration parsing.

MitigationImplement proper input validation and sanitization for all configuration data, specifically neutralizing or rejecting CRLF sequences (%0D%0A) during processing. Validate that configuration inputs conform to expected formats before acceptance.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify SD-330AC firmware version
    Access the device web interface or administrative console and locate the firmware version information, typically found under System Info, Status, or Device Settings.
    Affected if The displayed firmware version is lower than 1.50
  2. Identify AMC Manager software version
    Open AMC Manager and navigate to Help > About, or check the installed programs list in the operating system to locate the software version.
    Affected if The installed AMC Manager version is lower than 5.1.0
  3. Verify configuration data access is available
    Locate the configuration data input interface on the device web console or within AMC Manager, typically under Configuration, Settings, or Network settings sections.
    Affected if Configuration data input fields are accessible and available for modification
  4. Test for CRLF injection point in configuration inputs
    Submit configuration data containing CRLF sequences (or URL-encoded %0D%0A) to any configuration input field and observe if the sequences are processed or stored without neutralization.
    Affected if CRLF sequences are accepted and persisted in the configuration without being rejected or sanitized

You are affected if you are running SD-330AC firmware below version 1.50 or AMC Manager below version 5.1.0 AND you have access to configuration data input features that accept and process user-supplied values.

Upgrade available Upgrade to 1.50 / 5.1.0 or later
Fixed in 1.505.1.0
Interim mitigation

Implement proper input validation and sanitization for all configuration data, specifically neutralizing or rejecting CRLF sequences (%0D%0A) during processing. Validate that configuration inputs conform to expected formats before acceptance.

Recommended fix Moderate confidence

SD-330AC Firmware >= 1.50 and AMC Manager >= 5.1.0

  1. 1. Identify the current firmware version of the SD-330AC device by accessing its administration interface or checking the device status page
  2. 2. Identify the current version of AMC Manager by opening the application and navigating to Help > About, or checking the installed programs list
  3. 3. For SD-330AC: Download the firmware version 1.50 or later from the official silex technology support website (www.silex.jp)
  4. 4. For AMC Manager: Download version 5.1.0 or later from the official silex technology support website (www.silex.jp)
  5. 5. Apply the firmware update to the SD-330AC device following the manufacturer's upgrade instructions (typically via web UI or dedicated upgrade tool)
  6. 6. Install AMC Manager version 5.1.0 or later on the management system
  7. 7. After upgrading, verify the new versions are correctly installed and the services are functioning normally
  8. 8. Test that configuration data processing works correctly with the updated versions
Caveat Review release notes for any configuration or behavioral changes between previous versions and 1.50/5.1.0; some legacy configuration parameters may need adjustment
