HIGH 8.8

DescriptionCVE.org

An OS Command Injection vulnerability exists in the web-based Traceroute diagnostic utility of International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver Web Management Interface version 101. An authenticated attacker can inject arbitrary shell metacharacters (such as the pipe | operator) into the flags parameter, leading to the execution of arbitrary operating system commands with root privileges.

Executive ViewAI

Why It Matters

A critical command injection vulnerability affects IDC SFX Series SuperFlex Satellite Receiver web management interfaces, allowing unauthenticated attackers to execute arbitrary commands with high severity (CVSS 8.8). Organizations operating this equipment face immediate risk of system compromise, data exfiltration, and operational disruption, particularly if these receivers are internet-exposed or accessible from untrusted networks.

Business Impact: High

Compensating Controls

Disable or restrict access to the Traceroute diagnostic utility at the application level if available; implement WAF rules to block malicious input patterns targeting command injection in the Traceroute endpoint; enforce strict network segmentation limiting management interface access to dedicated administrative VLANs; require VPN authentication for any remote management access; implement egress filtering to limit command execution impact; enable comprehensive logging and monitoring of the management interface for suspicious activity.
