Vulnerability Title
IDC SFX2100 Satellite Receiver bgpd/ospfd/ripd/zebra Config Credential Disclosure via World-Readable Files
Source: CVE Program / CVE List V5
Vulnerability 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.
