"The remote host is running phpSysInfo, a PHP script that parses the
/proc entries on Linux systems and displays them in HTML. 

The version of phpSysInfo installed on the remote host is affected by
multiple cross-site scripting vulnerabilities due to its failure to
sanitize user input to the 'sensor_program' parameter of 'index.php'
and the 'text[language]', 'text[template]', and 'VERSION' parameters
of 'system_footer.php'.  If PHP's 'register_globals' setting is
enabled, a remote attacker can exploit these flaws to have arbitrary
script rendered in the browser of a user in the context of the
affected website.");
