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
Authentication Bypass by Spoofing vulnerability in Mitsubishi Electric Corporation GOT2000 Series GT27 model versions 01.14.000 to 01.47.000, Mitsubishi Electric Corporation GOT2000 Series GT25 model versions 01.14.000 to 01.47.000 and Mitsubishi Electric Corporation GT SoftGOT2000 versions 1.265B to 1.285X allows a remote unauthenticated attacker to disclose sensitive information from users' browsers or spoof legitimate users by abusing inappropriate HTML attributes.

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 · high confidence

Authentication bypass by spoofing vulnerability in Mitsubishi Electric GOT2000 Series HMI products allows remote unauthenticated attackers to disclose sensitive information from users' browsers or spoof legitimate users by abusing inappropriate HTML attributes in the web interface.

MitigationApply vendor-supplied patches to update to versions beyond 01.47.000 for GT27/GT25 and beyond 1.285X for SoftGOT2000; until patched, limit network exposure and monitor for suspicious access patterns.

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 the GOT2000 product type
    Determine if the system uses GT SoftGOT2000 software, GT27 hardware, or GT25 hardware. Check software installations or hardware labels on the HMI device.
    Affected if The product is any of these three: GT SoftGOT2000, GT27, or GT25
  2. Check GT SoftGOT2000 version
    Open GT SoftGOT2000, navigate to Help > Version Information, or check the software's about dialog to find the exact version number (format like 1.XXXc).
    Affected if Version is >= 1.265b and < 1.290c
  3. Check GT27/GT25 firmware version
    On the HMI device, access System Information from the utility menu, or use GT Designer3 software to connect and read the firmware version (format like 01.XX.XXX).
    Affected if Firmware version is >= 01.14.000 and < 01.48.000
  4. Verify web interface is enabled
    Check if the HMI's web server or remote access feature is configured and active. For SoftGOT2000, verify if the virtual GOT web functions are enabled. For hardware GOT, check if Ethernet/web functions are enabled in the device settings.
    Affected if The web interface is accessible over the network (the vulnerability requires the web interface to be exposed)

The system is affected if it runs any GT SoftGOT2000 version >= 1.265b and < 1.290c, or GT27/GT25 firmware >= 01.14.000 and < 01.48.000, AND the web interface is enabled and network-accessible.

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 · scoped
Upgrade available Upgrade to 01.48.000 / 1.290c or later
Fixed in 01.48.0001.290c
Interim mitigation

Apply vendor-supplied patches to update to versions beyond 01.47.000 for GT27/GT25 and beyond 1.285X for SoftGOT2000; until patched, limit network exposure and monitor for suspicious access patterns.

Recommended fix High confidence

GT27/GT25 firmware: 01.48.000 or later | GT SoftGOT2000: 1.290c or later

  1. Identify the exact installed version of Mitsubishi Electric GOT2000 Series (GT27 or GT25) firmware or GT SoftGOT2000 software
  2. Navigate to the official Mitsubishi Electric download page for GOT2000 series firmware or GT SoftGOT2000 software
  3. Download the firmware version 01.48.000 or later for GT27/GT25, or version 1.290c or later for GT SoftGOT2000
  4. Follow the official Mitsubishi Electric firmware update procedure documented in the GOT2000 User's Manual
  5. Apply the firmware update to the GOT2000 device or update the GT SoftGOT2000 installation
  6. Verify the updated version matches or exceeds the fixed release (GT27/GT25: 01.48.000, GT SoftGOT2000: 1.290c)
Caveat Review Mitsubishi Electric firmware update documentation for any special update procedures or prerequisites; firmware updates may require device downtime
