CVE-2026-32958
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 · uneditedSD-330AC and AMC Manager provided by silex technology, Inc. use a hard-coded cryptographic key. An administrative user may be directed to apply a fake firmware update.
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 confidenceThe SD-330AC device and AMC Manager software from silex technology contain a hard-coded cryptographic key used in their firmware update verification mechanism. An attacker who social-engineers an administrative user into applying a malicious firmware update can bypass cryptographic validation due to this static key, allowing execution of unauthorized firmware.

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.
-
Check SD-330AC device firmware versionAccess the device web interface or administrative console and locate the firmware version information, typically found under System, Status, or Firmware Update sectionsAffected if Firmware version is displayed as less than 1.50
-
Check AMC Manager software versionOpen AMC Manager and navigate to Help > About, or check the installed program's version property in the Windows Programs and Features listAffected if AMC Manager version is less than 5.1.0
-
Determine if firmware update feature is accessibleCheck if the device administrative interface includes a firmware update or firmware upgrade option, and verify whether the update mechanism uses cryptographic verificationAffected if Firmware update feature exists and uses a static verification key rather than per-device or dynamically generated keys
You are affected if the SD-330AC firmware is below version 1.50 or AMC Manager is below version 5.1.0, and the firmware update mechanism relying on the hardcoded key is enabled on your device.
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.

Contact silex technology for patched firmware that removes hardcoded keys; verify all firmware updates originate from official vendor sources before installation.
SD-330AC Firmware 1.50; AMC Manager 5.1.0
- Obtain the SD-330AC firmware version 1.50 or later from the official silex technology support website
- Obtain AMC Manager version 5.1.0 or later from the official silex technology support website
- Follow the official silex technology firmware update procedure to upgrade the SD-330AC device to firmware version 1.50 or later
- Follow the official silex technology software update procedure to upgrade AMC Manager to version 5.1.0 or later
- Verify that the upgraded versions are correctly installed by checking the firmware version on the SD-330AC and the software version of AMC Manager
