Bug #13447 Updated: Security not blocking "unlink" delete functions

ID: 13447 Updated by: sander Reported By: ajo@dpzone.com Old Status: Open Status: Feedback Bug Type: Filesystem function related Operating System: windows 2000 PHP Version: 4.0.6 New Comment: Can you try adding a trailing slash (c:/pr/), and can you try 4.1.0??? Previous Comments: ------------------------------------------------------------------------ [2001-09-26 04:48:28] ajo@dpzone.com Running PHP in Apache using the MODULE configuration. Apache/1.3.14 (Win32) PHP/4.0.6 mod_ssl/2.7.2 OpenSSL/0.9.6 running. With the following: php_admin_flag safe_mode on php_admin_value open_basedir c:/pr php_admin_value doc_root c:/pr php_admin_value user_dir c:/pr IT SUCCESSFULLY blocks reads in directories other than c:/pr, but it DOES NOT block unlinks (file deletion) outside. So... My users cannot read other users files, however they can delete anything they want. Very strange. I DO NOT care about it checking "UIDs" as I do not create different Users for each USER... I want to be able to restrict access to a directory and call it good. <?php echo "Peace!"; //unlink ("c:/test.txt");// UNLINK WORKS (This should fail) $fp = fopen ("c:/test.txt", "r"); // FAILS SECURITY CHECK echo "Dude10"; ?> ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=13447&edit=1
