NMAP NSE that enumerates VNC authentication types
Nmap VNC Authentication Scanner Steve Ocepek [email protected]
Use this Nmap script to quickly determine the types of authentication supported by each targeted VNC server. Particularly useful when probing large environments for servers that do not require authentication.
Features include:
Simply copy the file to your local Nmap scripts directory, or the local directory from which Nmap is being executed. An example, though this path will vary between operating systems and distributions:
/usr/local/share/nmap/scripts/
Call the script using the --script Nmap argument.
Example:
nmap -P0 --script=vnc-auth.nse -p 5900 192.168.2.166
Each discovered VNC server will be listed with its supported security type(s):
Starting Nmap 5.00 ( http://nmap.org ) at 2009-10-28 13:32 EDT Interesting ports on 192.168.2.166: PORT STATE SERVICE 5900/tcp open vnc |_ vnc-auth: RFB 003.008, Security Types: 02(VNC Authentication)
Nmap done: 1 IP address (1 host up) scanned in 0.14 seconds
