Can you explain this vulnerability to me?
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.
How can this vulnerability impact me? :
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.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
