# Vulnerability description :
#
# Session Fixation is an attack that permits an attacker to hijack a valid user session.
# The attack explores a limitation in the way the web application manages the session ID,
# more specifically the vulnerable web application. When authenticating a user,
# it doesn't assign a new session ID, making it possible to use an existent session ID.
# The attack consists of inducing a user to authenticate himself with a known session ID,
# and then hijacking the user-validated session by the knowledge of the used session ID.
# The attacker has to provide a legitimate Web application session ID and try to make the victim's browser use it.
