CVE-2026-29128

Datacast Sfx2100 Firmware hard-coded credentials

10.0 CRITICALPublic exploitEPSS 0.30%
  1. Published5 Mar 2026

Description

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.
