Operating system: Windows
PHP version: 5.2.6
PHP Bug Type: Safe Mode/open_basedir
Bug description: safe_mode bypass
Description:
------------
safe_mode bypass with a preceding backslash. tested with exec(), system()
and passthru(). on windows only.
Sorry, I do feel this bug concerns a security issue but I got no response
from [EMAIL PROTECTED] after sending 2 emails from 2 different accounts
about 6 weeks ago.
Reproduce code:
---------------
on commandline:
php -n -d safe_mode=on -r "exec('\ping 192.168.222.1');"
with PHP script and enabled safe_mode in php.ini:
<? exec('\ping 192.168.222.1'); ?>
Expected result:
----------------
safe_mode turned on should block code execution from exec() and other
functions.
Actual result:
--------------
By adding a backslash infront of the command the command got executed
anyhow.
