After taking the 617 SANS class in Orlando I got curious and wanted to get Scapy working natively on OS X rather than messing about with a Virtual Linux image. A key motivator was the fact that I was running out of space on my Macbook Air and not only had to carry around an external USB WiFi adapter, but also a USB hard drive.
A few hours ago I committed a new script created by Vikas Singhal to Nmap. It implements the functionality to initiate a tftp transfer of a Cisco configuration through SNMP. In order to do so, the device obviously needs to support this functionality, and you need to know the private SNMP-community string.
The script can either save the configuration to a file in a directory specified as a script argument or displays it on screen. In order to achieve this, I’ve contributed with a minimal tftp server, implemented as a Nmap NSE library. This eliminates the need to setup and configure a separate tftp-server as it’s all being taken care of transparently by Nmap.
In order to try it out you can either update from subversion or download the tftp library and the snmp-ios-config script and place them in nselib and the scripts directory. For more information on how to run the script, check out the documentation.
Chris Woodbury and I have been working on some new exciting features and enhancements to the ms-sql scripts and library in Nmap lately. We’ve been working in a separate branch which will hopefully get merged to trunk really soon. Chris work has been of high quality and very inspiring! It got me to pick up some of the stuff I meant to implement, but hadn’t got to, and has brought a number of new great ideas. For a good summary of changes consult the following nmap-dev mailing list thread.
Among the many new features and enhancements I’m really happy to see are:
- Support for more precise version checking, by using the prelogin packet (same technique as SQLPing)
- Support for connections using named pipes, rather than tcp-sockets
- Support for integrated authentication (Ntlmv1) in addition to the existing SQL authentication
- Support for connecting to named instances in addition to specific tcp ports
- Support for running each of the ms-sql scripts against all instances detected by the discovery mechanisms
If you would like to give the scripts a run they’re available from here, and will hopefully be merged to trunk really soon.
I just posted 15 new nmap scripts to the nmap-dev mailing list. For anyone curios to check them out have a look over here. I’ve been working on these new scripts for a while and they add yet more database support to nmap allowing users to perform password guessing against both Oracle and Informix servers. In addition custom SQL queries can be made to Informix servers directly from nmap.
I’ve also created a number of scripts which can be suitable when pen testing Lotus Domino. These scripts include support for collecting Internet password hashes and user ID files. ID files can be collected both as an authenticated user from the person web view or unauthenticated using the vulnerability CVE-2006-5835. Oh, and you can add Lotus Domino 8.5 to the list of vulnerable versions in that advisory. There are also two scripts that allow you to interact with the IBM Lotus Domino remote console. One script allows for password guessing, while the other one allows you to interact with the console ones your authenticated.
There’s a tiny script in the zip file that supports querying for registered objects in a ORB Naming Service using the GIOP protocol.
Last but not least I’ve created a framework for other password guessing scripts to use. The framework runs using multiple worker threads and does all the looping, iteration and other basic logic used by most of my previous brute scripts.
The zip file included in the nmap-dev post can be downloaded from here. Please help me out testing the scripts so that they can be added to the subversion version of nmap!
I’ve got an e-mail from someone who had trouble with my old rdesktop password guessing patch. So, I took a new look at it and updated it to do more than just dump core
It’s available for download from the rdesktop page.
During the development of my AFP library for Nmap I came a cross a critical vulnerability in Apple’s implementation of AFP on Snow Leopard. The vulnerability occurs due to improper input validation and allows an attacker to access (list, read, and/or write) files in the parent directory of any AFP sharepoint.
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.
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.
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.
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 …
