'Description' => %q{
This module exploits an unauthenticated SQL injection vulnerability affecting Zabbix
versions 2.0.8 and lower. The SQL injection issue can be abused in order to retrieve an
active session ID. If an administrator level user is identified, remote code execution
can be gained by uploading and executing remote scripts via the 'scripts_exec.php' file.
