Detailsinfo

A vulnerability was found in International Datacasting IDC SFX2100 SuperFlex Satellite Receiver (the affected version is unknown). It has been classified as problematic. This affects an unknown code of the component Configuration Handler. The manipulation with an unknown input leads to a insufficiently protected credentials vulnerability. CWE is classifying the issue as CWE-522. The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval. This is going to have an impact on confidentiality. The summary by CVE is:

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.
