Edit report at http://bugs.php.net/bug.php?id=52189&edit=1 ID: 52189 Updated by: pajoye@php.net Reported by: staff at humaninternals dot com Summary: Certain errors are not sanitized against htmlspecialchars -Status: Open +Status: Bogus Type: Bug Package: Unknown/Other Function Operating System: Windows PHP Version: 5.3.0 New Comment: Do not set display_errors. Previous Comments: ------------------------------------------------------------------------ [2010-06-26 12:14:20] staff at humaninternals dot com Wrong package. ------------------------------------------------------------------------ [2010-06-26 10:52:06] staff at humaninternals dot com 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. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52189&edit=1
