DescriptionCVE.org

International Datacasting Corporation (IDC) SFX Series SuperFlex(SFX2100) SatelliteReceiver contains hardcoded and insecure credentials for the admin account. A remote unauthenticated attacker can use these undocumented credentials to access the satellite system directly via the Telnet service, leading to potential system compromise.

Executive ViewAI

Why It Matters

CVE-2026-29119 presents critical security risk, a hard-coded credentials vulnerability rated CVSS 9.8. Successful exploitation could allow attackers to execute arbitrary code or commands on affected systems, potentially leading to full system compromise. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.

Business Impact: Severe

Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls; (2) Enable MFA where possible; (3) Monitor authentication logs for anomalous access.
