Hardcoded Cryptographic Key Vulnerability in GX Earth ONT Models_CVE-2026-45433

{
    "lastseen": "",
    "description": "This vulnerability exists in GX Earth 2022 ONT models due to the presence of hardcoded RSA private key within the device firmware. A remote attacker could exploit this vulnerability by extracting the cryptographic private key from the firmware, which could lead to decryption of HTTPS traffic and Man-in-the-Middle (MITM) attacks on the targeted device.",
