Using Nmap for pentesting eDirectory

While doing a security review the other day I came across Novell eDirectory running on Windows. It’s been a while since I looked at eDirectory and while it’s a lot of LDAP, the servers were also running the Netware Core Protocol (NCP). I noticed that there wasn’t any NCP support in Nmap so I decided that I would implement some basic support. I ended up writing a NCP library and the following two scripts:

  • ncp-enum-users – enumerates eDirectory users
  • ncp-serverinfo – lists some basic server information

The scripts should work against NCP running on both Netware, Linux and Windows. Here’s some sample output from both scripts:

In addition to the NCP scripts I wrote a LDAP script (ldap-novell-getpass) that extract the plain-text password of a given user, in case the “Allow admin to retrieve passwords” option is enabled in the password policy. On success, the script returns the following result:

All of the scripts have been committed to Nmap and are available through subversion.

Nmap-scripts cleanup

I’ve cleaned up the Nmap scripts page a bit to better reflect reality. Most of the scripts published on that page have been commited to the Nmap development release. I’m actively working on getting the remainder commited to. Once the scripts have been commited, they’re no longer maintained here. So, in order to try them out I recommend you to install the latest development release of Nmap. In order to do so, follow the steps outlined here.

5 new SNMP scripts in Nmap SVN

As of yesterday there are now 5 new SNMP scripts in the development release of Nmap. I commited a new ASN.1 library a re-worked SNMP library and 5 new scripts. The new scripts are:

  • snmp-netstat shows listening and connected sockets
  • snmp-processes shows process information including name, pid, path and parameters
  • snmp-win32-services shows the names of running Windows services
  • snmp-win32-shares shows the names and path of Windows shares
  • snmp-win32-software shows a list of installed Windows software
  • snmp-win32-users shows a list of local Windows users

Make sure to check them out over at insecure.org. In order to use them you need to check out the development sources from subversion. More info on that over here.

nfs-showmount total re-write

I received a bug report for my Nmap nfs-showmount script a few days ago. I ended up re-writing the whole thing as it was my first script, which is short for “ugly as hell”. I moved all NFS and RPC stuff into a new library called rpc.lua and added some more functionality as well.

I’ve also added two more scripts that make use of the library nfs-get-stats and nfs-get-dirlist. The first retrieves disk usage for each export and the second lists files on a share. They’re both available from the nmap-scripts page as usual.

Nmap does more MySQL

I’ve just added some code to my Nmap MySQL library that enables query support. With this code in place it’s possible to run queries against MySQL directly from a Nmap script. In order to illustrate this I’ve added three scripts: mysql-list-users, mysql-list-databases and mysql-show-variables.

While messing around with the library I also cleaned up the code for mysql-brute and mysql-empty-password. All of the scripts that query the database obviously require credentials to do so. These can be provided on the command line using script arguments mysqluser and mysqlpassword or by running the mysql-brute or mysql-empty-password on the same time. There are dependencies set up so that the query scripts wait until these two scripts have collected the credentials. Here’s some sample output from the scripts …

DAAP script for nmap

I’ve added a script that queries a DAAP service for it’s library. Depending on the version of the service it then attempts to query it for for a list of artists, albums and songs. It’s available, together with more other scripts, over at the nmap-scripts page.

Here’s a sample output when running against the Firefly Media Server:
