- Severity: CVSS 8.7 (High), CNA
- Vector: 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
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-06-04 · Updated: 2026-06-04

## Affected

- GX INDIA GX Earth 2022: version E2022 - 3.1.2A, version E2022 - 3.1.5AV, version E2022 - 1.1ASL
- GX INDIA GX Earth 1010: version E1010-1.1ASL

## 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.
