CVE-2007-6077 Information

Description

The session fixation protection mechanism in cgi_process.rb in Rails 1.2.4 as used in Ruby on Rails removes the :cookie_only attribute from the DEFAULT_SESSION_OPTIONS constant which effectively causes cookie_only to be applied only to the first instantiation of CgiRequest which allows remote attackers to conduct session fixation attacks. NOTE: this is due to an incomplete fix for CVE-2007-5380.
