[PHP] safe mode bug ?
I came upon a strange problem when trying to list directory's in safe
mode as a normal user. Of course I expected this not to work, because
safe_mode disables the possibility of reading files that not belong to
the owner of the PHP-file. However, it does not seem to check for
directory ownerships. (debian stable, PHP4.1.2). PHP does give a warning
about safe_mode (as seen below) but then nicely lists the directory :(
This means any user can just browse through any dir. on my system. PHP
obviously still obeys UNIX file permissions so i could tighten up those,
and enable basedir restrictions and stuff, but it looks to me that this
is just a (major) bug ?
The php script
$file = '/etc';
if ($handle = opendir($file))
while (false !== ($file = readdir($handle)))
*Warning*: SAFE MODE Restriction in effect. The script whose uid is
1059 is not allowed to access /etc owned by uid 0 in
*/home/robert/hensel.nl/robert/www/test_dir.php* on line *5*
FILE:init.d ....(goes on)
safe_mode: On On
safe_mode_exec_dir: no value no value
safe_mode_gid: Off Off
safe_mode_include_dir: no value no value
thanks in advance for any thoughts about this.
