AnalysisAIv1 – Mar 12, 2026

Authenticated attackers can execute arbitrary OS commands with root privileges on IDC SFX2100 satellite receivers through command injection in the web-based Ping utility, bypassing input filters by using alternate shell metacharacters like the pipe operator. Public exploit code exists for this vulnerability, and no patch is currently available. The flaw affects the web management interface and allows complete system compromise for any authenticated user.

Technical ContextAI · show details

Classified as CWE-78 (OS Command Injection). Affects Sfx2100 Firmware. 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.

HIGH 8.8

DescriptionCVE.org

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 ViewAI

Why It Matters

Organizations operating IDC SFX Series SuperFlex Satellite Receiver Web Management Interface version 101 face a critical remote code execution risk through the web-based ping utility. An unauthenticated attacker can inject operating system commands to gain full control of affected satellite receivers, potentially disrupting satellite communications, data services, and business-critical operations.

Business Impact: High

Compensating Controls

Implement WAF rules to block requests to /IDC_Ping/main.cgi containing shell metacharacters (|, &, ;, $, backticks, etc.) in the IPaddr parameter. Restrict network access to the web management interface via firewall rules and VPN-only access. Disable the ping utility feature if operationally feasible. Implement enhanced logging and monitoring for anomalous command execution on affected devices. Segment satellite receiver management interfaces on isolated network VLANs.
