Fixed HTTP Session Cookies

This script is Copyright (C) 2010-2017 Tenable Network Security, Inc.

Synopsis :

The remote web application is affected by a session fixation

Description :

The remote web application uses cookies to track authenticated users.
If the session cookie is already present before authentication, it
remains unchanged after a successful login. A remote attacker can
exploit this to hijack a valid user session.

Session cookies are expected to be unpredictable in a secure web
application. If HTTP cookies can be manipulated (by injecting client-
side JavaScript for example) then the attacker does not have to break
the pseudo-random generator, and the web application is vulnerable to
a 'session fixation' attack.

Solution :

Fix the application so that the session cookie is re-generated after
successful authentication.

Risk factor :

Medium / CVSS Base Score : 5.1
