CVE-2026-28775

An unauthenticated Remote Code Execution (RCE) vulnerability exists in the SNMP service of International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver. The deployment insecurely provisions the `private` SNMP community string with read/write access by default. Because the SNMP agent runs as root, an unauthenticated remote attacker can utilize `NET-SNMP-EXTEND-MIB` directives, abusing the fact that the system runs a vulnerable version of net-snmp pre 5.8, to execute arbitrary operating system commands with root privileges.
