#41824 [Opn->WFx]: move_uploaded_file open_basedir problem

ID: 41824 Updated by: jani@php.net Reported By: mueller at intertrend dot de -Status: Open +Status: Wont fix Bug Type: Safe Mode/open_basedir Operating System: SUSE LINUX 10.0 PHP Version: 4.4.7 New Comment: We are sorry, but we can not support PHP 4 related problems anymore. Momentum is gathering for PHP 6, and we think supporting PHP 4 will lead to a waste of resources which we want to put into getting PHP 6 ready.

And as that flag is gone... Anyway, even with PHP 4.4.3 and above, if 'upload_tmp_dir' and the destination of move_uploaded_file() are on the same FS, everything works fine as as "rename()" is used (which is not affected by open_basedir restrictions). I "solved" the issue by moving my upload_tmp_dir to the same FS where my websites are stored. Bye, G. ------------------------------------------------------------------------ [2007-10-08 09:45:00] gkieffer at evolutive dot org Hi, I have the same behavior (that contradicts the documentation): source argument of move_uploaded_file() is checked against open_basedir. As requested by 'tony2001@php.net', I've tried the latest PHP4 snapshot (php4-STABLE-200710080830) and the open_basedir restriction is still enforced on the source parameter of move_uploaded_file. 4.4.8-dev (snapshot): KO 4.4.7 : KO 4.4.6 : KO 4.4.5 : KO 4.4.3 : KO 4.4.2 : OK 4.4.1 : (I assume, I haven't tested it) 4.4.0 : OK Here's some extra info about my environment: Linux Debian Sarge Apache 2.0.59 (compiled, not a Debian pkg) PHP 4.4.x compiled as a module for Apache 2.0.59 upload_tmp_dir = /var/run/php-file-uploads open_basedir = /wrk1/htdocssds/site.fqdn/ /var and /wrk1 are different (ext3) filesystems. destination dir of move_uploaded_file() is /wrk1/htdocssds/site.fqdn/backoffice/photo_gest/ If I add '/var/run/php-file-uploads/' to open_basedir everything works fine but this is not the expected behavior. Hope it helps !
