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
The Web-GUI on WAGO Series 750-88x (750-330, 750-352, 750-829, 750-831, 750-852, 750-880, 750-881, 750-882, 750-884, 750-885, 750-889) and Series 750-87x (750-830, 750-849, 750-871, 750-872, 750-873) devices has undocumented service access.

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 WAGO 750 series PLC devices contain an undocumented service accessible through the web-based management interface. This hidden service, present across multiple device models in the 750-88x and 750-87x series, provides unauthorized access with a critical severity CVSS rating, likely enabling remote code execution or administrative access without proper authentication.

MitigationApply vendor-provided firmware updates when available; until then, disable the web GUI interface or isolate affected devices on a restricted network segment to minimize exposure.

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 WAGO PLC model number
    Access the device's web-based management interface or check the device labeling/management console to confirm the exact model (e.g., 750-830, 750-849, 750-871, 750-872, 750-873, 750-330, 750-352, 750-829).
    Affected if The model number matches any of the following: 750-830, 750-849, 750-871, 750-872, 750-873, 750-330, 750-352, or 750-829.
  2. Retrieve the installed firmware version
    Log into the device web interface or use the WAGO management tools to view the firmware version information. This is typically found under System > Firmware or a similar diagnostics section.
    Affected if The firmware version is below the threshold for your specific model (750-830: <06, 750-849: <08, 750-871: <11, 750-872: <07, 750-873: <07, 750-330: <14, 750-352: <14, 750-829: <14).
  3. Confirm the web-based management interface is enabled
    Check the device configuration to determine if the web-based management interface (HTTP/HTTPS) is currently enabled and accessible on the device.
    Affected if The web-based management interface is enabled and reachable on the network.
  4. Test for the undocumented service endpoint
    Using a web browser or HTTP client, attempt to access the device through common web paths to identify any undocumented or hidden service endpoints not documented in the official administration manual.
    Affected if Any undocumented service endpoints are accessible without authentication or with default credentials.

You are affected if your device is a WAGO 750 series model listed above, runs firmware below the specified version threshold, and has the web-based management interface enabled.

Upgrade available Upgrade to 06 / 07 / 08 or later
Fixed in 060708
Interim mitigation

Apply vendor-provided firmware updates when available; until then, disable the web GUI interface or isolate affected devices on a restricted network segment to minimize exposure.

Recommended fix High confidence

Firmware 06+ for 750-830, 08+ for 750-849, 11+ for 750-871, 07+ for 750-872/750-873, 14+ for 750-330/750-352/750-829

  1. 1. Identify the exact WAGO 750 series model number (e.g., 750-830, 750-849, etc.) from the device label or Web-GUI
  2. 2. Check the current firmware version via the Web-GUI (typically under System > Firmware or similar menu)
  3. 3. Navigate to the official WAGO download portal or contact WAGO support to obtain the firmware update for your specific model
  4. 4. For 750-830: upgrade to firmware version 06 or later
  5. 5. For 750-849: upgrade to firmware version 08 or later
  6. 6. For 750-871: upgrade to firmware version 11 or later
  7. 7. For 750-872 or 750-873: upgrade to firmware version 07 or later
  8. 8. For 750-330, 750-352, or 750-829: upgrade to firmware version 14 or later
Caveat Industrial firmware updates may require downtime and could affect existing configurations; test in a non-production environment first and ensure you have a backup
