Official description

A vulnerability has been found in SourceCodester Prison Management System 1.0. The impacted element is an unknown function of the component Login. The manipulation leads to session fixiation. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.

The underlying weakness: Session Fixation

Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.

How developers prevent this class of flaw

  • Invalidate any existing session identifiers prior to authorizing a new user session.
  • For platforms such as ASP that do not generate new values for sessionid cookies, utilize a secondary cookie. In this approach, set a secondary cookie on the user's browser to a random value and set a session variable to the same value. If the session variable and the cookie value ever don't match, invalidate the session, and force the user to log on again.
  • Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
