Executive Summary

This vulnerability exists in GX Earth 2022 ONT models because the device firmware contains a hardcoded RSA private key.

A remote attacker can exploit this by extracting the cryptographic private key from the firmware.

With this key, the attacker could decrypt HTTPS traffic and perform Man-in-the-Middle (MITM) attacks on the targeted device.

Impact Analysis

The vulnerability can allow a remote attacker to intercept and decrypt secure HTTPS communications intended for the device.

This could lead to exposure of sensitive data transmitted over the network.

Additionally, the attacker could perform Man-in-the-Middle (MITM) attacks, potentially manipulating or spying on the data exchanged.

Compliance Impact

This vulnerability involves a hardcoded RSA private key in the device firmware, which can be exploited to decrypt HTTPS traffic and perform Man-in-the-Middle (MITM) attacks. Such a security flaw can lead to unauthorized access to sensitive data transmitted by the device.

Because of the potential exposure of sensitive information, this vulnerability could negatively impact compliance with data protection standards and regulations such as GDPR and HIPAA, which require the protection of personal and health information against unauthorized access and interception.
