Received Received - Intake
Unauthenticated RCE in IDC SFX Series SNMP Service

Publication date: 2026-03-04

Last updated on: 2026-03-09

Assigner: Gridware

Description
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.

Executive Summary

This vulnerability is an unauthenticated Remote Code Execution (RCE) issue in the SNMP service of the International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver. The device insecurely sets the SNMP community string named 'private' with read/write access by default. Since the SNMP agent runs with root privileges and uses a vulnerable version of net-snmp (pre 5.8), an attacker can exploit NET-SNMP-EXTEND-MIB directives to execute arbitrary operating system commands remotely without authentication.

Impact Analysis

This vulnerability allows an unauthenticated remote attacker to execute arbitrary commands on the affected device with root privileges. This can lead to full system compromise, unauthorized access to sensitive data, disruption of services, and potentially using the compromised device as a foothold for further attacks within a network.
