If we try to change it, flatnuke will ask us to log in again. The code is: $req = $_SERVER["REQUEST_URI"]; if (strstr($req, "myforum=")) die(_NONPUOI); So, we can bypass this filter, using nullbyte and login as admin. For example, Replace: myforum=yourusername with: myforum%00=adminusername PHP Execution PoC: I saw that in download module, if we set to "1" the fneditmode, we can make directory. So, we can write a description for the directory, and this description will be saved in /Download/[Dir_Name]/description.it.php . Yes, we can insert php code in the description and it will be execute! Nice, dontcha? : P --------------------------------------------------------------- Original here: http://www.inj3ct-it.org/exploit/flatnuke3-cm.txt
