From 3aaf38f938ef78c09bf91419d882e10f23d2be52 Mon Sep 17 00:00:00 2001 From: Aleisha Amohia Date: Mon, 29 Jul 2024 03:53:06 +0000 Subject: [PATCH] Bug 37508: Throw error if password column is detected in SQL report This enhancement prevents SQL queries from being run if they would return a password field from the database table. To test: 1. Run tests and notice they fail t/db_dependent/Reports/Guided.t 2. Apply patch and restart services 3. Create a public report with an SQL report which would access a password column in a database table 4. Try to run the report. Notice you are met with an error and the results are not shown. 5. Access the JSON URL, you should not get the results and should be shown an error 6. Confirm tests pass t/db_dependent/Reports/Guided.t Sponsored-by: Reserve Bank of New Zealand --- C4/Reports/Guided.pm | 7 +++++ .../modules/reports/guided_reports_start.tt | 4 +++ svc/report | 7 ++--- t/db_dependent/Reports/Guided.t | 30 ++++++++++++++++++- 4 files changed, 43 insertions(+), 5 deletions(-) diff --git a/C4/Reports/Guided.pm b/C4/Reports/Guided.pm index f69804c2838..8558666041e 100644 --- a/C4/Reports/Guided.pm +++ b/C4/Reports/Guided.pm @@ -623,6 +623,13 @@ sub execute_query { ->info("Report finished: $report_id") if $report_id; return ( $sth, { queryerr => $sth->errstr } ) if ( $sth->err ); + + foreach my $column ( @{ $sth->{NAME_lc} } ) { + if ( $column eq 'password' ) { + return ( $sth, { passworderr => $column } ); + } + } + return ($sth); } diff --git a/koha-tmpl/intranet-tmpl/prog/en/modules/reports/guided_reports_start.tt b/koha-tmpl/intranet-tmpl/prog/en/modules/reports/guided_reports_start.tt index b039bd5cf95..44c9cf766b8 100644 --- a/koha-tmpl/intranet-tmpl/prog/en/modules/reports/guided_reports_start.tt +++ b/koha-tmpl/intranet-tmpl/prog/en/modules/reports/guided_reports_start.tt @@ -1436,6 +1436,10 @@ [% error.queryerr | html %]
