Nikto - short introduction

● You manage several Web servers/applications● Need to find potential problems and security

vulnerabilities, including: - Server and software misconfigurations - Default files and programs - Insecure files and programs - Outdated servers and programs

Nikto - short introduction● Web server scanner,● Created by : David Lodge and Chris Sullo,● Version 1.00 Beta released on: December 27, 2001 ● Current version: 2.1.5,● Written in: Perl,● The name is taken from the movie: The Day The Earth Stood Still,● Sponsored by: Sunera LLC,● Official page : http://www.cirt.net/nikto2.

Nikto - short introduction● Open source,● Performs test against web servers

for multiple items: - Looks for over 6500 potentially dangerous files/CGIs, - Checks for outdated versions of over 1250 servers, - Looks for version specific problems on over 270 servers, - Attempts to identify installed web servers and software, - Checks for the presence of multiple index files and HTTP server options,● Output can be saved in a variety of formats: text, XML, HTML.

Burp Suite● Integrated platform for performing security testing of web

applications,● Its tools work great togheter to support the entire testing process,

from initial mapping and analysis of an application’s attack surface, through to finding and exploiting security vulnerabilities,

● Gives full control , meaning combine advanced manual techniques with state-of-the-art automation for fast, effective results.

Burp Suite - key components● Proxy - an intercepting proxy , which lets you inspect and modify traffic

between your browser and the target application,● Spider - an application aware spider, for crawling content and

functionality,● Scanner - an advanced web application scanner, for automating the

detection of numerous types of vulnerabilities,● Intruder - an intruder tool, for performing powerful customized attacks

to find and exploit unusual vulnerabilities,● Repeater - a repeater tool, for manipulating and resending individual

requests,● Sequencer - a sequencer tool, for testing the randomness of session

tokens,● Ability to: save your work and resume your work later, write plugins.

Burp Suite - Nikto

Proxy - can intercept the http requests and show them in proper format so it can be used to analyse the queries made by Nikto and discover vulnerabilities.

perl nikto.pl -h localhost -useproxy http://localhost:8080/

Wikto ● Roles: checks for vulnerabilities in webservers,also in the

implementation, it tries to find interesting directories and files on the web site and it looks for simple scripts that can be abused,

● Written in: .NET C#,● Version: 2.1.0.0.● Release date: 2008-12-14,● Created by: sensepost,● Cost: free,● License:GPL,● Nikto for Windows with extra features: fuzzy logic eror code

checking, a back-end miner, Google assisted directory mining, real time HTTP request/response monitoring.

Wikto - Nikto

Wikto uses Nikto’s database to perform different checks against web server.

Nikto DB

Nmap● Network Mapper,● Roles: network discovery and security analysis,● Technique: uses IP raw packets ,● Determine: what host are available on the network, what services

(application name and version) those hosts are offering, what operating systems (and OS versions) they are running and other,

● Free and Open Source,● Available with: command line and GUI viewer( Zenmap),● Well documented and supported,● Portable: runs on al major operating systems,● Won numerous awards and was featured in twelve movies ,● Official site: http://nmap.org/.

Nmap -NiktoScenario: Nikto supports scanning multiple hosts via text file of host names or IPs. A host file may also be a Nmap output in “greppable” format.

Operating systemWindows 7, 64 bit

NiktoVersion 2.1.5

Nmapcommand-line zip file: nmap-6.40-win32.zip

Steps● Download and install Nikto and Nmap,● Put in the Environment Variables, Path for

the two folders of the programs mentioned above,

● In Start search for cmd, wait to open Command Prompt,

● Type the following for localhost, port 80:

nmap -p80 localhost/24 -sT -Pn -oG - | nikto.pl -h - -oG - greppable format, name of the file - , to be passed through stdin/stdout to Nikto,

-sT - TCP connect scan,

-Pn - no ping , disable host discovery.

Metasploit -NiktoHow to: Metasploit Framework

● Set a PostgreSQL database (u:msf, pass:password123)

● Set web xmlrpc interface at :127.0.0.1, port 55553,

● Run a command like: db_vulns , after, to see how Nikto tested for and detected the vulnerability

[*] Time: Tue Nov 10 00:22:14 UTC 2010 Vuln: host=localhost port=80 proto=tcp name=nikto.005988 refs=OSVDB-5292

[*] Time: Wed Nov 10 00:23:08 UTC 2010 Vuln: host=localhost port=80 proto=tcp name=nikto.006453 refs=OSVDB-40478

How to: Nikto(logging to)

● Install Perl modules RPC::XML::Client and RPC::XML

● Add your own test for a vulnerability in

Nikto/Plugins directory

"006XXX","40478","b","/tikiwiki/tiki-graph_formula.php?w=1&h=1&s=1&min=1&max=2&f[]=x.tan.phpinfo()&t=png&title=","GET","200","","","","","This device may have a vulnerable installation of TikiWiki.","",""

where 006XXX is the one number greater than the last entry in db_test file, 40478 is the osvdb number

● perl nikto.pl -h localhost -Format msf

-o msf:password123@http://localhost:55553/RPC2

all scan results are saved in the msf database in realtime.

Nessus -Nikto● Started: as a project in 1998,● by: Renaud Deraison, ● to: provide a free remote security scanner, ● but: in 2005 Tenable Network Security take it ● and: make it closed source.● Can perform scans on: networks, operating systems, web applications,mobile devices,● Most popular and capable scanner, for UNIX systems particularly,● Support for different operating systems,● Has an extensive plugin database, updated daily, (plugin = vulnerability test written in

NASL(Nessus Attack Scripting Language) )● Various formats of the scan results : plain text, XML, HTML and Latex,● Last stable release: 5.2.1/May 7, 2013.

Nessus -NiktoNikto can be integrated in NessusHow: when Nessus finds a web server,automatically launch Nikto.

Settings:

1. Nikto installation, 2. Put nikto.pl in PATH, 3. Ensure that nikto.nasl is present in the

Nessus install(Nasl Wrapper),4. Run “nessusd -R”, 5. Finally restart nessusd.

OpenVAS -Nikto● Open Vulnerability Assessment System,● Began under the name GNessUs, as a fork of the Nessus open source tool,● Framework of several services and tools,● Roles: vulnerability scanning and vulnerability management solution,● Cost: free,● Developed by: Greenbone Networks ,● Last stable release: 6.0/April 17, 2013.

Nikto● is integrated, as a tool, into OpenVAS,● the OpenVAS plugin for Nikto integration(nikto.nasl) needs to be present and enabled,● the results of a Nikto scan are included in OpenVAS final scan.
