Assigner: Gridware

Description
The web-based Ping diagnostic utility (/IDC_Ping/main.cgi) in International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite  Receiver Web Management Interface version 101 is vulnerable to OS Command Injection. The application insecurely parses the `IPaddr` parameter. An authenticated attacker can bypass server-side semicolon exclusion checks by using alternate shell metacharacters (such as the pipe `|` operator) to append and execute arbitrary shell commands with root privileges.

Executive Summary

This vulnerability exists in the web-based Ping diagnostic utility (/IDC_Ping/main.cgi) of the International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver Web Management Interface version 101.

The issue arises because the application insecurely parses the `IPaddr` parameter, allowing an authenticated attacker to bypass server-side semicolon exclusion checks.

By using alternate shell metacharacters such as the pipe `|` operator, the attacker can append and execute arbitrary shell commands with root privileges on the server.

Impact Analysis

An attacker who successfully exploits this vulnerability can execute arbitrary commands on the affected system with root privileges.

This can lead to full system compromise, including unauthorized access to sensitive data, modification or deletion of files, disruption of services, and potentially using the compromised system as a foothold to attack other systems.
