DoS via tables corruption in WordPress

Hello 3APA3A!

There is DoS vulnerability in WordPress, about which I wrote in 2009 (http://websecurity.com.ua/3152/, on English http://perishablepress.com/important-security-fix-for-wordpress/comment-page-5/#comment-71666), which allows to conduct DoS attack or reinstall of the engine (depending on corrupted table). And in 2012 (http://websecurity.com.ua/5774/, on English http://securityvulns.ru/docs27968.html) I wrote that developers hadn't fixed it, even they said so, and they made new DoS vulnerability.

In April 2012 I wrote my article "Attack via tables corruption in MySQL" (http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2012-May/008363.html) and in July made English version of the article (http://websecurity.com.ua/articles/attack-via-tables-corruption-in-mysql/). Where I described vulnerabilities in WordPress and IPB which are based on my conception of attack via tables corruption.

On Saturday I published a video with my WordPress DoS exploit (http://www.youtube.com/watch?v=kwv5ni_qxXs), which shows this DoS attack on one security site on WordPress. Vulnerable are all versions of WordPress. This video is a proof of this vulnerability in WP and of the attack described in the article.
