From 62fb5b3320c9fe5d865ac82cb438450ad9261812 Mon Sep 17 00:00:00 2001 From: Amit Gupta Date: Thu, 11 Jul 2024 23:13:06 +0530 Subject: [PATCH] Bug 37323: Escape characters in patron image picture upload To Test 1. Create a file name for example: test.zip`curl xxxxtesting.informaticsglobal.com`.zip where the domain is one you can watch the logs from. 2. Go to Tools and click on Upload patron images choose option zip file and upload the file. 3. Check /var/log/apache2/access.log and see the curl with the IP "xx.xxx.xx.xxx - - [11/Jul/2024:23:10:33 +0530] "GET / HTTP/1.1" 200 267 "-" "curl/7.68.0" 4. Apply the patch 5. Repeat 2 and 3 step and check no error is coming for the Remote execution error. 6. Test uploading actual zip file and images still works. --- tools/picture-upload.pl | 1 + 1 file changed, 1 insertion(+) diff --git a/tools/picture-upload.pl b/tools/picture-upload.pl index 2383fba885..4d6597fdee 100755 --- a/tools/picture-upload.pl +++ b/tools/picture-upload.pl @@ -89,6 +89,7 @@ if ( ( $op eq 'cud-Upload' ) && ($uploadfile || $uploadfiletext) ) { my $dirname = File::Temp::tempdir( CLEANUP => 1 ); my $filesuffix; + $uploadfilename =~ s/[^A-Za-z0-9\-\.]//g; if ( $uploadfilename =~ m/(\..+)$/i ) { $filesuffix = $1; } -- 2.25.1
