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 Improper Authorization issue was discovered in Sierra Wireless AirLink Raven XE, all versions prior to 4.0.14, and AirLink Raven XT, all versions prior to 4.0.11. Several files and directories can be accessed without authentication, which may allow a remote attacker to perform sensitive functions including arbitrary file upload, file download, and device reboot.

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

Improper authorization vulnerability in Sierra Wireless AirLink Raven XE (versions prior to 4.0.14) and Raven XT (versions prior to 4.0.11) allows unauthenticated remote attackers to access sensitive files and directories, enabling arbitrary file upload, file download, and device reboot operations.

MitigationUpdate firmware to version 4.0.14 (Raven XE) or 4.0.11 (Raven XT) or later. Additionally, restrict network access to management interfaces using firewalls or VLANs as a defense-in-depth measure until patching is complete.

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 device model
    Access the device web interface or CLI and check the model name under System Information or Device Status. Look for 'Raven XE' or 'Raven XT' designation.
    Affected if The device is a Sierra Wireless AirLink Raven XE or Raven XT gateway.
  2. Check Raven XE firmware version
    In the web interface, navigate to Device Status or About page. Note the firmware version displayed. For CLI, use 'at!gen' or check the boot prompt information.
    Affected if The device is a Raven XE and the firmware version is lower than 4.0.14.
  3. Check Raven XT firmware version
    In the web interface, navigate to Device Status or About page. Note the firmware version displayed. For CLI, use 'at!gen' or check the boot prompt information.
    Affected if The device is a Raven XT and the firmware version is lower than 4.0.11 (or any version, since all versions are affected).
  4. Verify management interface exposure
    Review firewall rules, VLAN configurations, or access control lists to determine if the device management web interface (typically ports 80/443) is reachable from untrusted networks or the public internet.
    Affected if The management interface is accessible from untrusted networks, allowing unauthenticated attackers to exploit the authorization bypass.

The device is affected if it is a Sierra Wireless AirLink Raven XE (firmware < 4.0.14) or Raven XT (any version) with its management interface accessible from untrusted networks.

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

Update firmware to version 4.0.14 (Raven XE) or 4.0.11 (Raven XT) or later. Additionally, restrict network access to management interfaces using firewalls or VLANs as a defense-in-depth measure until patching is complete.

Recommended fix Moderate confidence

Airlink Raven XE: firmware 4.0.14 or later; Airlink Raven XT: firmware 4.0.11 or later

  1. 1. Identify the current firmware version of the Airlink Raven XE or XT device through the device's web interface or administrative console
  2. 2. For Airlink Raven XE devices: download firmware version 4.0.14 or later from Sierra Wireless official support site
  3. 3. For Airlink Raven XT devices: download firmware version 4.0.11 or later from Sierra Wireless official support site
  4. 4. Access the device administrative interface and navigate to the firmware upgrade section
  5. 5. Upload the downloaded firmware file to the device
  6. 6. Wait for the firmware upload and installation to complete - do not power off the device during this process
  7. 7. After reboot, verify the new firmware version is installed and confirm the device is operational
  8. 8. Verify the vulnerability is mitigated by attempting to access the previously unauthenticated paths (should now require authentication)
Caveat No breaking changes expected for security patch updates; verify critical operational functions after upgrade
