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.

AnalysisAI

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.
