What the vulnerability does

01Description

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.
