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.
