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
Use of insufficiently random values vulnerability exists in Vnet/IP communication module VI461 of YOKOGAWA Wide Area Communication Router (WAC Router) AW810D, which may allow a remote attacker to cause denial-of-service (DoS) condition by sending a specially crafted packet.

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

Insufficiently random values in the Vnet/IP communication module VI461 of the AW810D Wide Area Communication Router allow a remote attacker to cause denial-of-service by sending specially crafted packets. The vulnerability stems from predictable or weak random number generation used in the protocol, potentially allowing an attacker to infer or manipulate communication sequences.

MitigationApply vendor patches for the AW810D firmware addressing random value generation in the Vnet/IP module. If no patch is available, implement network segmentation and firewall rules to limit exposure to untrusted network sources reaching the affected module.

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. Confirm AW810D model identification
    Locate the device model identifier in the system information, hardware label, or management interface - verify the device is specifically an AW810D Wide Area Communication Router
    Affected if The device model is not AW810D (different models are not affected by this specific CVE)
  2. Check firmware version against affected range
    Access the firmware version information through the device management interface, CLI, or system diagnostics. Compare the installed version to the r12 baseline - versions r12 and earlier are within the affected range
    Affected if Firmware version is r12 or earlier (r1 through r12)
  3. Verify Vnet/IP module VI461 is configured
    Locate the module or feature configuration for Vnet/IP communication (may be listed as VI461 or Vnet/IP in the module list, protocol settings, or communication interface configuration)
    Affected if The Vnet/IP module VI461 is present and enabled in the configuration
  4. Assess network accessibility of the Vnet/IP service
    Review network exposure settings, firewall rules, or interface bindings for the Vnet/IP communication module to determine if it listens on accessible network interfaces
    Affected if The Vnet/IP module is bound to network interfaces reachable from untrusted networks

A user is affected if the device is an AW810D router running firmware r12 or earlier with the Vnet/IP module VI461 enabled and accessible from the network where crafted packets could be received.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply vendor patches for the AW810D firmware addressing random value generation in the Vnet/IP module. If no patch is available, implement network segmentation and firewall rules to limit exposure to untrusted network sources reaching the affected module.
