The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via the "live_stream_code" POST parameter to "/plugin/LiveChat/getChat.json.php" file. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability requires the Live Chat plugin to be enabled and may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
