Hi Shyaam! Yes, developers should not pushed such vulns in the final code - not mistakenly, not intentionally.
In this case: the very name test.php
Such things happens and I also saw many times when particularly admins of web sites or web developers (such as design studios) mistakenly left such files as test.php (with phpinfo) at working web sites. But it's about unintentional cases. This is exactly intentional case. Developers of WooThemes intentionally added this test.php file with holes into their commercial themes to allow users of their themes to make "debugging". I.e. they have added additional (and holed) feature and did it officially (because it's mentioned in changelog) many years ago into many if not all their themes. As it can be found in changelog for Live Wire (http://demo.woothemes.com/wp-content/themes/livewire/changelog.txt) and many other themes. Here is a quote: 2008.08.06 - Version 1.1 * includes/test.php - Added phpinfo() file for debugging resizer on buggy hosts So from 2008 in this and many other (if not all) their themes there is such additional feature - with Information Leakage and Cross-Site Scripting holes, in addition to all those holes which I wrote earlier. After I've found this information in changelog, I saw that it's intentional. And it's not first case when I see some web developers intentionally adding php-scripts with phpinfo - and adding IL and XSS holes - it's because they are not aware about the risks. WooThemes themes are commercial ones, so I've not bought any of them and I'm not using them. And like in case of previous holes in 89 their themes, I've found these holes on sites in Internet (in those indexed by Google). I've found only 15 affected themes from all WooThemes WordPress themes - only in those which were indexed by Google - and there can be other their themes with these vulnerabilities.

In this case: the very name test.php is indicative of the scenario where the developers leave open backdoors for their testing purposes and forget to remove them during a push for production. This is common in every industry. On Jun 4, 2011, at 12:17 PM, "MustLive" <mustlive () websecurity com ua> wrote:
Hello list! I want to warn you about Information Leakage and Cross-Site Scripting vulnerabilities in multiple themes for WordPress. ------------------------- Affected products: ------------------------- Vulnerable are the next themes by WooThemes: Live Wire (all three themes from Live Wire series), Gotham News, Typebased, Blogtheme, VibrantCMS, Fresh News, The Gazette Edition, NewsPress, The Station, The Original Premium News, Flash News, Busy Bee, Geometric. Other vulnerable themes for WP are possible. ---------- Details: ---------- In different themes there is test.php - script with phpinfo() - which leads to Information Leakage (disclosure of FPD and other important information about the server) and XSS (in PHP < 4.4.1, 4.4.3-4.4.6). Information Leakage (WASC-13): http://site/wp-content/themes/_theme's_name_/includes/test.php XSS (WASC-08): http://site/wp-content/themes/_theme's_name_/includes/test.php?a[]=%3Cscript%3Ealert(document.cookie)%3C/script%3E For Live Wire the script is placed at address http://site/wp-content/themes/livewire/includes/test.php, similarly for other themes. ------------ Timeline: ------------ 2011.04.11 - announced at my site. 2011.04.12 - informed developers. 2011.06.04 - disclosed at my site. These vulnerabilities are still not fixed by developers. So users of these themes are need to fix the vulnerabilities manually (e.g. by deleting of this script). I mentioned about these vulnerabilities at my site (http://websecurity.com.ua/5071/).
