CVE-2025-66357
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 · uneditedCHOCO TEI WATCHER mini (IB-MCT001) contains an issue with improper check for unusual or exceptional conditions. When the Video Download feature is in a specific communication state, the product's resources may be consumed abnormally.
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 vulnerability in the CHOCO TEI WATCHER mini (IB-MCT001) device's Video Download feature. When the feature is in a specific communication state, improper handling of exceptional conditions causes abnormal resource consumption, likely leading to device unresponsiveness or service degradation.

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 the device modelLocate the physical device or check network inventory for device with model identifier IB-MCT001 or product name CHOCO TEI WATCHER mini. This is typically a IoT monitoring device.Affected if The device is an IB-MCT001 (CHOCO TEI WATCHER mini) unit.
-
Confirm firmware versionAccess the device administration interface or check device documentation for the installed firmware version. The firmware is identified as 'Inaba Ib Mct001 Firmware'.Affected if Any firmware version is installed on the IB-MCT001 device (all versions are affected).
-
Verify Video Download feature statusCheck the device configuration or web interface for the Video Download feature. This feature is typically found in the device settings or monitoring configuration panel.Affected if Video Download feature is enabled or configured on the device.
-
Assess network exposureDetermine if the device is accessible over the network (LAN or WAN). Check router/firewall rules for any port forwards or access lists allowing external access to the device.Affected if The device is network-accessible, particularly from untrusted networks, increasing the attack surface for triggering the vulnerable communication state.
You are affected if you have an IB-MCT001 (CHOCO TEI WATCHER mini) device with Video Download feature enabled and network accessibility, since all firmware versions contain the vulnerability in the Video Download feature's handling of exceptional conditions during specific communication states.

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.
From vendor dataIf available, apply vendor firmware updates addressing this issue. As a compensating control, restrict network access to the device and avoid initiating Video Download operations during the vulnerable communication state until a patch is available.
