The remote host is vulnerable to a SQL Injection attack.
The remote host is running Calendarix, a calendar application for web servers. This version of Calendarix is vulnerable to a flaw in the way that it parses user-supplied HTTP data. An attacker exploiting this flaw would be able to send specially formatted SQL commands that, upon being parsed, would execute on the remote database server. This can lead to a loss of confidentiality, integrity, and availability on the remote database server.
Upgrade or patch according to vendor recommendations.
