KSN Reference: 2004-06-03 0001 TIP
---------------------------------------------------------------------------
Title
-----
The Netgear WG602 Accesspoint contains an undocumented
administrative account.
Date
----
2004-06-03
Description
-----------
The webinterface which is reachable from both interfaces (LAN/WLAN)
contains an undocumented administrative account which cannot be disabled.
Any user logging in with the username "super" and the password "5777364"
is in complete control of the device.
This vulnerability can be exploited by any person which is able to reach
the webinterface of the device with a webbrowser.
A search on Google revealed that "5777364" is actually the phonenumber
of z-com Taiwan which develops and offers WLAN equipment for its OEM
customers.
Currently it is unknown whether other Vendors are shipping products
based on z-com OEM designs.
Systems Affected
----------------
Vulnerable (verified)
WG602 with Firmware Version 1.04.0
Possibly vulnerable (not verified)
WG602 with other Firmware Versions
WG602v2
All other z-com derived WLAN Accesspoints
Proof of concept
----------------
Download the WG602 Version 1.5.67 firmware from Netgear
( http://kbserver.netgear.com/support_details.asp?dnldID=366 )
and run the following shell commands on a UNIX box:
$ dd if=wg602_1.5.67_firmware.img bs=1 skip=425716 > rd.img.gz
$ zcat rd.img.gz | strings | grep -A5 -B5 5777364
Which results in the following output:
