COMMAND
Netgear configuration accessible to unauthentified users
SYSTEMS AFFECTED
Netgear FM114P Wireless Router firmware v1.4 Beta Release 17 others
have not been tested
PROBLEM
b.stickler [http://intex.ath.cx] found :
documents/files can be accessed without authentication by using escaped
directory traversal from the accessible /upnp/service directory.
this results f.ex. in the ability to grab configuration file without
authentication on the router (remotely possible when remote
configuration is enabled) by using the following url:
http://ip-or-hostname:port/upnp/service/%2e%2e%2fnetgear.cfg
this config file contains dialup-password, dynamic dns-configuration
password and the main router configuration options. the router-password
and wep-keys are NOT included in this configuration file.
as far as i can say from my tests, there is no possibility to submit
data to forms on the router web-interface. (if so, it would be possible
to reset password or access wep-keys).
SOLUTION
?
Workaround
==========
To avoid the possibility for others to grab your config-file, simply
disable the remote management of the router (if enabled anyway).
disabling the upnp option of the router software does not affect the
behaviour.
