GHSA-5H68-JG5G-W367

Vulnerability from github – Published: 2026-06-04 15:30 – Updated: 2026-06-04 15:30

Details

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.

Severity

8.7 (High)


                  
                    CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
