                  Issue
                  Allaire has recently been notified of a security issue in the Allaire Forums 2.0.5 software. This
                  behavior allows users to view and post to secure conference threads via unsecured conferences
                  and/or through email. The security issue in the code exists in certain unscoped variables and the
                  base-coding schema of forums itself. The flaw spans multiple files; (files are listed below), and
                  involves a certain variable called "rightAccessAllForums." This variable was not scoped properly
                  inside the forums code, allowing the user the ability to not only post and view conference of
                  which they are not part, but also allowing users to sign up to Forums conferences which have
                  not yet been created.

                  Affected Software Versions

                       Allaire Forums 2.x 

                  What Allaire is Doing
                  Allaire has released new templates for Allaire Forums that should close this vulnerability. The
                  new templates correct the coding problem by explicitly setting two values,
                  "rightAccessAllForums" and "rightModerateAllForums" to be automatically hard-coded "False"
                  in the Application.cfm; those values are then called for authentication in the rest of the files.
                  These modifications also force Client.Forums_AccessAllowed to contain a list of all accessible
                  forums.

                  The template files were created to replace the existing files on your system. It is recommended
                  you back up your existing data before over-writing or replacing any files. You will also need to
                  modify these files to reflect any personal coding changes you have made to your existing
                  Forums installation.

                  Below is a listing of the new template files and the locations where they should be placed on
                  your server:

                       File Name 
                                           Directory to Place In 
                  Application.cfm
                                    {webroot}\{Forums Home Directory}\
                  Conf_ThreadList.cfm
                                    {webroot}\{Forums Home Directory}\
                  MessageEdit_Action.cfm
                                    {webroot}\{Forums Home Directory}\forms\
                  Search_Results.cfm
                                    {webroot}\{Forums Home Directory}\
                  _NewSession.cfm
                                    {webroot}\{Forums Home Directory}\Queries\



                  What Customers Should Do
                  Customers should back up all existing data and place the new templates in the proper
                  directories (see above). This should resolve the issue. This fix also contains the coding fix for
                  the cross-site scripting issue (ASB00-05).
