From d1eda960f25bdab06dcef383c0b64488042c029a Mon Sep 17 00:00:00 2001 From: Liz Rea Date: Fri, 26 Jan 2018 14:12:47 +1300 Subject: [PATCH] Bug 20083 - Information disclosure when (mis)using the MARC Preview feature The MARC Preview feature in the Staff client (catalogue/showmarc.pl) does not check whether a user is logged in or not. As a consequence, it can be used to obtain information that would normally be available to logged-in users only. For example, you can view any bibliographic record by passing a value to the 'id' argument, but you can also view records as they were imported (normally done via the 'Staged MARC management' tool). All three 17.11 installations currently listed at https://wiki.koha-community.org/wiki/Koha_Demo_Installations are affected by this issue, as demonstrated by the URLs below: http://koha.adminkuhn.ch:8080/cgi-bin/koha/catalogue/showmarc.pl?importid=1&viewas=html http://pro.demo1711-koha.test.biblibre.eu/cgi-bin/koha/catalogue/showmarc.pl?id=1000&viewas=html https://staff-kohademo.equinoxinitiative.org/cgi-bin/koha/catalogue/showmarc.pl?id=1&viewas=html It should be noted that this only applies to XSLT-enabled installations. - note that I (Liz) am only putting this patch in a testable form, patch/changes written by Andreas Roussos --- catalogue/showmarc.pl | 21 +++++++++++---------- 1 file changed, 11 insertions(+), 10 deletions(-) diff --git a/catalogue/showmarc.pl b/catalogue/showmarc.pl index 11c4f39..2d5c193 100755 --- a/catalogue/showmarc.pl +++ b/catalogue/showmarc.pl @@ -37,6 +37,17 @@ use C4::ImportBatch; use C4::XSLT (); my $input= new CGI; +my ( $template, $loggedinuser, $cookie ) = get_template_and_user( + { + template_name => "catalogue/showmarc.tt", + query => $input, + type => "intranet", + authnotrequired => 0, + flagsrequired => { catalogue => 1 }, + debug => 1, + } +); + my $biblionumber= $input->param('id'); my $importid= $input->param('importid'); my $view= $input->param('viewas')||''; @@ -70,16 +81,6 @@ if($view eq 'card' || $view eq 'html') { Encode::encode_utf8(C4::XSLT::engine->transform($xml, $xsl)); } else { - my ( $template, $loggedinuser, $cookie ) = get_template_and_user( - { - template_name => "catalogue/showmarc.tt", - query => $input, - type => "intranet", - authnotrequired => 0, - flagsrequired => { catalogue => 1 }, - debug => 1, - } - ); $template->param( MARC_FORMATTED => $record->as_formatted ); output_html_with_http_headers $input, $cookie, $template->output; } -- 2.7.4
