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
E3 Site Supervisor Control (firmware version < 2.31F01) has a floor plan feature that allows for an unauthenticated attacker to upload floor plan files. By uploading a specially crafted floor plan file, an attacker can access any file from the E3 file system.

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

The E3 Site Supervisor Control firmware versions prior to 2.31F01 contain a path traversal vulnerability in the floor plan upload feature. An unauthenticated attacker can upload a specially crafted floor plan file containing path traversal sequences (e.g., ../../) to read arbitrary files from the device's filesystem, potentially exposing sensitive configuration data, credentials, or other system files.

MitigationUpgrade E3 Site Supervisor Control firmware to version 2.31F01 or later. If immediate patching is not possible, restrict network access to the floor plan upload functionality using network segmentation or firewall rules to prevent unauthenticated access.

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. Determine the installed firmware version
    Access the E3 Supervisory Controller web interface or check system information page to retrieve the current firmware version. Compare it against the affected range: versions prior to 2.31F01 are vulnerable.
    Affected if Firmware version is lower than 2.31F01 (e.g., 2.30, 2.29, etc.)
  2. Locate the floor plan upload feature
    Navigate through the E3 Supervisor web interface to find the floor plan upload functionality, typically under settings, configuration, or maintenance sections.
    Affected if The floor plan upload feature is present and accessible in the interface
  3. Check network accessibility of the upload function
    Determine if the E3 Supervisory Controller is directly accessible from untrusted networks or the internet. Verify firewall rules and network segmentation around the device.
    Affected if The device or its floor plan upload endpoint is reachable from unauthenticated/untrusted network segments
  4. Verify if path traversal protection is missing
    Attempt to access the device locally or review any available configuration logs to see if the floor plan upload accepts path traversal sequences without sanitization. This may require access to system logs or attempting a controlled test if authorized.
    Affected if The system accepts path traversal sequences (such as ../ or ../../) in file upload parameters without rejecting or sanitizing them

You are affected if your E3 Supervisory Controller runs firmware version lower than 2.31F01 and the floor plan upload feature is accessible on your network.

Upgrade available Upgrade to 2.31f01 or later
Fixed in 2.31f01
Interim mitigation

Upgrade E3 Site Supervisor Control firmware to version 2.31F01 or later. If immediate patching is not possible, restrict network access to the floor plan upload functionality using network segmentation or firewall rules to prevent unauthenticated access.

Recommended fix Moderate confidence

E3 Supervisory Controller Firmware version 2.31F01

  1. Identify the current firmware version of the E3 Supervisory Controller by accessing the device management interface or checking the system information page
  2. Obtain the official firmware version 2.31F01 from the device vendor's support website or through authorized distribution channels
  3. Access the E3 Site Supervisor administrative interface and navigate to the firmware update or system maintenance section
  4. Upload the firmware 2.31F01 file and initiate the update process according to the vendor's documented upgrade procedure
  5. Wait for the firmware update to complete and the device to reboot
  6. Verify the firmware version has been updated to 2.31F01 and confirm the device is functioning normally
  7. Test the floor plan upload feature to ensure it works correctly with the patched firmware
