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
An issue was discovered in Digi ConnectPort LTS before 1.4.12. A vulnerability in the file upload handling of a web application allows manipulation of file paths via POST requests. This can lead to arbitrary file uploads within specific directories, potentially enabling privilege escalation when combined with other vulnerabilities.

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

A path traversal vulnerability in the web application's file upload functionality allows attackers to manipulate file paths via POST requests, enabling arbitrary file uploads within specific directories on Digi ConnectPort LTS devices before version 1.4.12. This can lead to privilege escalation when chained with other vulnerabilities.

MitigationUpgrade Digi ConnectPort LTS to version 1.4.12 or later to remediate the vulnerability. If immediate upgrading is not feasible, restrict or disable the web application's file upload feature and implement file upload validation controls.

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 device model is Digi ConnectPort LTS
    Access the device web interface or use SNMP/CLI to retrieve the device model identifier. Look for 'ConnectPort LTS' in the system information or device status page.
    Affected if The device is not a Digi ConnectPort LTS (the vulnerability only affects this specific product line)
  2. Check installed firmware version
    Navigate to the device web interface System or Administration section to view the firmware version. Alternatively, access the device via CLI and run 'show version' or 'get version' command.
    Affected if The firmware version is lower than 1.4.12 (versions 1.4.12 and later contain the fix)
  3. Verify web application is accessible
    Attempt to reach the device's web interface over HTTP/HTTPS on the configured management port (typically 80 or 443). Confirm the login page or status page loads.
    Affected if The web application interface is exposed and reachable on the network
  4. Confirm file upload functionality is enabled
    Log into the web interface and look for file upload, firmware upgrade, configuration import, or similar features in the Administration or System settings menus.
    Affected if File upload or firmware upgrade features are accessible and enabled for authenticated users

A user is affected if they have a Digi ConnectPort LTS device running firmware version below 1.4.12 with the web interface and its file upload feature accessible on the network.

Upgrade available Upgrade to 1.4.12 or later
Fixed in 1.4.12
Interim mitigation

Upgrade Digi ConnectPort LTS to version 1.4.12 or later to remediate the vulnerability. If immediate upgrading is not feasible, restrict or disable the web application's file upload feature and implement file upload validation controls.

Recommended fix High confidence

Firmware 1.4.12 or later

  1. Check the current firmware version on the Digi ConnectPort LTS device via the web interface or console
  2. Navigate to Digi's official support page at www.digi.com and locate the ConnectPort LTS firmware download section
  3. Download firmware version 1.4.12 or later for your specific ConnectPort LTS model
  4. Access the device's web management interface and navigate to the firmware upgrade section
  5. Upload and install the downloaded firmware file following the on-screen instructions
  6. After the device reboots, verify the firmware has been updated by checking the version number in the web interface
