CRITICAL 10.0

DescriptionCVE.org

IDC SFX2100 Satellite Receiver firmware ships with multiple daemon configuration files for routing components (e.g., zebra, bgpd, ospfd, and ripd) that are owned by root but world-readable. The configuration files (e.g., zebra.conf, bgpd.conf, ospfd.conf, ripd.conf) contain hardcoded or otherwise insecure plaintext passwords (including “enable”/privileged-mode credentials). A remote actor is able to abuse the reuse/hardcoded nature of these credentials to further access other systems in the network, gain a foothold on the satellite receiver or potentially locally privilege escalate.

Executive ViewAI

Why It Matters

IDC SFX2100 Satellite Receiver firmware contains a critical vulnerability exposing routing daemon configurations to unauthorized access, potentially allowing attackers to intercept, manipulate, or disrupt satellite communications. This affects all organizations operating these devices and could compromise network integrity, service availability, and data confidentiality without immediate remediation.

Business Impact: Severe

Compensating Controls

Restrict file system permissions on daemon configuration files (/etc/quagga/ or equivalent) to 0600 (root-only access); implement strict network segmentation isolating SFX2100 devices to trusted networks only; deploy host-based intrusion detection on receiver devices; monitor and log all configuration file access attempts; disable unnecessary routing daemons if not required for operations; implement firewall rules blocking unauthorized routing protocol traffic (BGP port 179, OSPF port 89, RIP port 520); monitor vendor for patch releases and establish expedited testing/deployment procedures upon availability.

Attack Technique

Privilege Escalation HIGH

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
