The remote host is vulnerable to an flaw that allows attackers to execute arbitrary commands
The remote host is running Contenido, a web content-management application. This version of Contenido is vulnerable to an unspecified 'command execution' flaw. It is reported that an attacker can, by sending a malformed query, coerce the application into running system commands. This flaw can only be executed if the "allow_url_fopen" and "register_globals" PHP variables are enabled. Successful exploitation would result in loss of confidential data as well as a compromise of system integrity.
Upgrade to version 4.6.4 or higher.
