This patch addresses both security issues mentioned in the summary of the report
submitted by Frère Sébastien Marie included below.
---------------------------
The problem is here: 'C4/AuthoritiesMarc.pm' in the function 'DelAuthority':
The argument $authid is included directly (not via statement) in the SQL.
For the exploit of this problem, you can use 'authorities/authorities-home.pl'
with authid on the URL and op=delete (something like
"authorities/authorities-home.pl?op=delete&authid=xxx").
This should successfully call DelAuthority, without authentification...
(DelAuthority is call BEFORE get_template_and_user, so before authentification
[This should be an issue also...]).
Please note that the problem isn't only that anyone can delete an authority of
this choose, it is more general: with "authid=1%20or%1=1" (after inclusion sql
will be like: "delete from auth_header where authid=1 or 1=1") you delete all
authorities ; with "authid=1;delete%20from%xxx" it is "delete from auth_header
where authid=1;delete from xxx" and so delete what you want...
SQL-INJECTION is very permissive: you can redirect the output in a file (with
some MySQL function), so write thea file of you choose in the server, in order
to create a backdoor, and compromise the server.
