The NNdefaccts dataset made by nnposter is an alternate fingerprint dataset for the Nmap http-default-accounts.nse script.
The NNdefacts dataset can test more than 380 different web interfaces for default logins. For comparison, the latest Nmap 7.80 default dataset only supports 55.
Here are some examples of the supported web interfaces:
Network devices (3Com, Asus, Cisco, D-Link, F5, Nortel..)
Video cameras (AXIS, GeoVision, Hikvision, Sanyo..)
Application servers (Apache Tomcat, JBoss EAP..)
Monitoring software (Cacti, Nagios, OpenNMS..)
Server management (Dell iDRAC, HP iLO..)
Web servers (WebLogic, WebSphere..)
Printers (Kyocera, Sharp, Xerox..)
IP Phones (Cisco, Polycom..)
Citrix, NAS4Free, ManageEngine, VMware..
See the following link for a full list:
https://github.com/InfosecMatter/http-default-logins/blob/master/list.txt
The usage is quite simple — we simply run the Nmap script with the alternate dataset as a parameter. Like this:
nmap --script http-default-accounts --script-args http-default-accounts.fingerprintfile=~/http-default-accounts-fingerprints-nndefaccts.lua -p 80 192.168.1.1
This is already pretty great as it is.
Nmap script limitations
Now the only caveat with this solution is that the http-default-accounts.nse script works only for web servers running on common web ports such as tcp/80, tcp/443 or similar.
This is because the script contains the following port rule which matches only common web ports:
So what if we find a web server running on a different port — say tcp/9999? Unfortunately the Nmap script will not run because of the port rule..
..unless we modify the port rule in the Nmap script to match our web server port! And that’s exactly where this new tool comes handy.
Introducing default-http-login-hunter
The default-http-login-hunter tool, written in Bash, is essentially a wrapper around the aforementioned technologies to unlock their full potential and to make things easy for us.
The tool simply takes a URL as an argument:
default-http-login-hunter.sh <URL>
First it will make a local temporary copy of the http-default-accounts.nse script and it will modify the port rule so that it will match the web server port that we provided in the URL.
Then it will run the Nmap command for us and display the output nicely.
You find a default credentials for Apache Tomcat running on port tcp/9999. Now we could deploy a webshell on it and obtain RCE. But that one is meant for me the "acidic"
List of URLs
The tool also accepts a list of URLs in a file. So, for instance, we could feed it with URLs found during Nessus scans extracted using our Nessus CSV parser.
The tool will go through all the URLs one by one and check for default logins. Like this:
default-http-login-hunter.sh urls.txt
Here the tool found a default login to the Cisco IronPort running on port https/9443.
Resume-friendly
Another useful feature is that it saves all the results in the current working directory. So if it gets accidentally interrupted, it will just continue where it stopped. Like in this example:
Here we found some Polycom IP phones logins.
Staying up-to-date
To make sure that we have the latest NNdefacts dataset, just run the update command:
default-http-login-hunter.sh update
And that’s pretty much it. If you want to see more detailed output, use -v parameter in the command line.
