From 904e926ba0f407b24aa3d94be5afe37b5e3ec075 Mon Sep 17 00:00:00 2001 From: Fridolin Somers Date: Tue, 3 Nov 2020 09:19:34 +0100 Subject: [PATCH] Bug 26904: OPAC password recovery allows regexp in email When using OPAC password recovery form, opac/opac-password-recovery.pl : if one provides correct login and an email, there is a check that this email is one of patron's. This check uses RegExp with case insensitive : if ( $email && !( any { /^$email$/i } @emails ) ) This is a security issue since one can simply enter '.*'. Severity is normal because the login must be a correct. I propose to use simple string compare with lowercase to be case insensitive. Test plan : 1) Don't apply patch 2) Enable system preference 'OpacResetPassword' 3) Go to 'OPAC > Log in to your account > Forgot your password?' 4) Enter an existing userid or cardnumber and '.*' in 'Email' 5) The password recovery is created ! (check table 'borrower_password_recovery') 6) Apply patch 7) Enter an existing userid or cardnumber and '.*' in 'Email' 8) You get the message 'No account was found with the provided information.' 9) Enter an existing userid or cardnumber and in 'Email' the corresponding email but with different case 10) The password recovery is created (check table 'borrower_password_recovery') Signed-off-by: Nick Clemens Signed-off-by: Julian Maurice Signed-off-by: Jonathan Druart --- opac/opac-password-recovery.pl | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/opac/opac-password-recovery.pl b/opac/opac-password-recovery.pl index 57e13087c9..f4686bbb37 100755 --- a/opac/opac-password-recovery.pl +++ b/opac/opac-password-recovery.pl @@ -84,7 +84,7 @@ if ( $query->param('sendEmail') || $query->param('resendEmail') ) { $firstNonEmptyEmail = $emails[0] if @emails; # Is the given email one of the borrower's ? - if ( $email && !( any { /^$email$/i } @emails ) ) { + if ( $email && !( any { lc($_) eq lc($email) } @emails ) ) { $hasError = 1; $errNoBorrowerFound = 1; } -- 2.39.5
