Disclosure of authentication information|
Version(s): FVS318 ProSafe VPN Firewall; firmware 1.1 and prior versions|
A password disclosure vulnerability was reported in Netgear's ProSafe VPN Firewall router. When an administrator makes a backup of the configuration, the administrative password is stored in plain text.|
It is reported that the configuration backup file includes (among other data) the username for the ISP Internet connection and the password for the device's web management interface (the username for the web management interface is always 'admin').
A local user on the administrator's computer may be able to view the device's administrative password in the configuration backup file.|
No solution was available at the time of this entry.|
The author of the report suggests that administrators encrypt the backup file for storage.

\reporting, and real-time alerts. It initiates up to 8 IPSec VPN tunnels
simultaneously, reducing your operating costs and maximizing the security
and Network Address Translation (NAT) routing, up to 253 users can access
your broadband connection at the same time."
The web interface includes a backup option to store your current config
just in case anything happens....
For the most part, the file isn't readable except for a few words, in
particular, your Username to your ISP internet connection, and the password
to the web admin interface which listens on port 80 by default. This port
can be changed to whatever you like, but probably not many people do that.
I would consider this a local threat because you can only get to the web interface
from inside the local LAN. Unless you enable Remote Management, which listens on port
8080 by default.
The default username for the web interface can't be changed, it's always "admin"...
Any good admin makes a backup of their working configs ;)

Use PGP to encrypt your files, if Netgear doesn't encrypt them for you.
