LaCie Network Space CSRF

Hey again!

I though you needed a christmas present.
So, I kind of found a couple of CSRF vulnerabilities in the LaCie Network Space NAS v1.1.6, and I though:

Hey, it was a long time ago since I wrote here. So why not disclose something fun...

...so well folks, it appears that the NAS do not seperate HTTP GET and POST variables apart from each other.
One thing lead to another, and I started coding a JavaScript which toggled the blue LED on and off.
I kept working a bit on the script, and here it is, it scans the hardcoded network of 192.168.0.X (subnet 255.255.0.0) for NAS'es;
tries to logon with the default credentials:

Username: admin
Password: admin

Once logged in, it utilizes 2 CSRF vulnerabilites, one to turn off the annoying blue LED, and one to rename the NAS to H_ACKACK_NET.
The fun part of this is, the web-interface appears to run as root down beneth (uid=0) and it got this cute format feature...

*cough* rm -rf through CSRF *cough*

That's it.
It's short, but fun.
Maybe I inspired someone.

Merry Christmas & Ciao Bella!
