PoC:
|
|
|
|
When an user log in, flatnuke set him a cookie value like this:
|
|
myforum=nomeuser. 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
