## Technical details

An OS command injection vulnerability (CWE-78) exists in the 'ping' action of the Rapid7 InsightConnect Ping Plugin for Linux. The flaw is located in the handling of the 'host' parameter, where the application fails to properly sanitize input before using it to construct a shell command. A remote attacker can exploit this by supplying malicious characters or commands within the host field. Successful exploitation allows for arbitrary code execution with the privileges of the plugin process. The vulnerability is addressed in version 1.0.4.
