CVE-2018-14782
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 · uneditedNetComm Wireless G LTE Light Industrial M2M Router (NWL-25) with firmware 2.0.29.11 and prior. The device allows access to configuration files and profiles without authenticating the user.
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 confidenceThe NetComm Wireless G LTE Light Industrial M2M Router (NWL-25) with firmware 2.0.29.11 and prior contains an authentication bypass vulnerability that allows unauthenticated users to access configuration files and profiles. This is a critical security flaw as it exposes sensitive system configuration data without requiring any credentials.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelCheck the router label or access the web interface to confirm the model is NWL-25 (NetComm Wireless G LTE Light Industrial M2M Router)Affected if Device is not an NWL-25 model - this vulnerability only affects that specific model
-
Check the firmware versionLog into the router web interface (typically at 192.168.1.1) and navigate to Status or System Information page to view the firmware version, or use CLI command 'version' if telnet/ssh access is availableAffected if Firmware version is 2.0.29.11 or earlier - versions up to and including 2.0.29.11 are affected
-
Verify web interface accessibilityAttempt to access the router web interface without any credentials - try reaching the main configuration page directlyAffected if The web interface is accessible without authentication - the vulnerability allows unauthenticated access
-
Test for unauthenticated config file accessTry directly accessing configuration files or profiles via URL paths such as /cfg or /config, or check if common config export endpoints respond without loginAffected if Configuration files or profiles are returned without requiring authentication - this confirms the bypass is present
If the device is an NWL-25 router with firmware version 2.0.29.11 or earlier AND the configuration interface is accessible without credentials, the device is affected by this CVE.
Generated from the published advisory. Verify against your own configuration.
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.
From vendor dataUpdate the router firmware to a version newer than 2.0.29.11 that addresses this authentication bypass. If no patched firmware is available, implement network segmentation to isolate the device and consider replacing the affected hardware.
