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.

AnalysisAI

Authenticated attackers can achieve remote code execution with root privileges on IDC SFX2100 satellite receiver devices through OS command injection in the web-based Traceroute diagnostic tool. By injecting shell metacharacters into the flags parameter, an attacker can execute arbitrary operating system commands on the affected system. Public exploit code exists for this vulnerability, and no patch is currently available.
