This script is Copyright (C) 2008-2014 Tenable Network Security, Inc.


Synopsis :

The remote web server generates predictable session IDs.

Description :

The remote web server generates a session ID for each connection. A
session ID is typically used to keep track of the actions of a user
while he visits a website.

The remote server generates non-random session IDs. An attacker might
use this flaw to guess the session IDs of other users and therefore
steal their session.
