CVE-2026-45432
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 · uneditedThis vulnerability exists in GX Earth ONT models due to the transmission of user credentials in plaintext over HTTP in its web management interface. A remote attacker could exploit this vulnerability by intercepting network traffic to obtain sensitive authentication information, which could lead to unauthorized access to the targeted device.
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 GX Earth ONT devices contain a vulnerability where the web management interface transmits user credentials in plaintext over HTTP instead of using encrypted HTTPS. A remote attacker on the same network can intercept this unencrypted traffic to capture authentication credentials and gain unauthorized access to the device.

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.
-
Check if HTTP port 80 is open on the deviceUse a network port scanner (e.g., nmap -p 80 <device_ip>) or check the device's accessible network ports to determine if the web management interface is reachable over HTTP.Affected if HTTP port 80 is open and accepts connections, indicating plaintext web management is enabled.
-
Verify if HTTPS is enabled for the management interfaceAttempt to access the device over HTTPS (e.g., https://<device_ip>) and check if the connection succeeds or if TLS/SSL is available in the device's web configuration settings.Affected if HTTPS is not enabled or the device only accepts plaintext HTTP connections for management.
-
Inspect web login traffic for plaintext credential transmissionUse a packet capture tool (e.g., Wireshark or tcpdump) to capture traffic when authenticating to the device's web interface over HTTP. Observe if the POST request containing username and password fields is transmitted in cleartext.Affected if Login credentials are visible in plaintext within captured HTTP traffic.
-
Check device management protocol settingsAccess the device's administrative console or configuration panel and look for settings related to 'HTTP', 'HTTPS', 'SSL/TLS', or 'Web Management Access' to determine which protocols are enabled.Affected if The device allows or defaults to plaintext HTTP access for administrative functions.
The environment is affected if the GX Earth ONT device web management interface is accessible over HTTP and transmits authentication credentials without encryption.

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 dataEnable HTTPS on the web management interface and disable plaintext HTTP access. If the device does not support HTTPS, contact the vendor for a firmware update that includes TLS encryption support.
