The remote host contains a PHP application that is prone to a remote command execution attack.
The remote host is running a version of the ZABBIX web interface that is affected by a remote code execution vulnerability. The vulnerability exists in the 'extlang' parameter of the 'locales.php' script. Provided PHP's 'magic_quotes_gpc' setting is disabled, an unauthenticated remote attacker can exploit this to execute arbitrary code on the remote host subject to the privileges of the web server user ID. Note that this version of the ZABBIX web interface is also likely affected by a local file inclusion vulnerability and a cross-site request forgery vulnerability.
Upgrade to version 1.6.3 or higher.
