PHP version: 5.3SVN-2010-06-26 (snap)
Package: Output Control
Bug Type: Bug
Bug description:Certain errors are not sanitized against htmlspecialchars
Description:
------------
I have currently tested this on PHP 5.3.0 on a Windows XP environment.
Although it is unlikely that this type of data will be from user input but
consider the test script.
When an undefined index notice occurs the index itself is not sanitized
allowing
for XSS type attacks.
Again it is very unlikely that this should come from user input but it is
possible.
Test script:
---------------
error_reporting(E_ALL | E_STRICT);
$a = array();
echo $a['<script>alert("A")</script>'];
Expected result:
----------------
Notice: Undefined index: <script>alert("A")</script> in ...file...
Actual result:
--------------
Notice: Undefined index: in ...file...
And a script alert popup.
