Skipfish is an interactive sitemap for the targeted site by carrying out a recursive crawl and dictionary-based probes. The resulting map is then annotated with the output from a number of active (but hopefully non-disruptive) security checks. The final report generated by the tool is meant to serve as a foundation for professional web application security assessments.

Installation on Ubuntu/BackTrack (via Redspin)

Use the following commands in the terminal windows to install and run Skipfish. Replace OUTPUT_FOLDER and TARGETSITE with the domain name and the target’s URL respectively. Also change the wget URL to the URL of the latest version of Skipfish download available.

wget http://skipfish.googlecode.com/files/skipfish-1.29b.tgz
tar zxvf skipfish-1.01b.tgz
sudo apt-get install libidn11-dev
cd skipfish
make
cp dictionaries/default.wl skipfish.wl
./skipfish -o OUTPUT_FOLDER http://www.TARGETSITE.com

Trial Run

Installed SkipFish and ran on the target site, specs below.

Guest OS : BackTrack4 VM

Host OS : Windows Vista

RAM : 512MB

Application Size : Medium ( < 1000 Unique Pages )

Internet Speed : 1 MBPS

Skipfish Verbose

Skipfish displays the scan run statistics continuously during the run. Once the scan run is complete, we get to see the scan summary (shown in the below screenshot).

Websecurify is a powerful web application security testing environment designed from the ground up to provide the best combination of automatic and manual vulnerability testing technologies. This tool automatically identifies web application vulnerabilities by using advanced discovery and fuzzing technologies.

WebSecurify is available in major OS platforms – Windows, Mac and Linux. Its even available as a Chrome extension.

Post Updated:

• Target site that requires authentication
• Info on Chrome Plugin

ZeroDayScan is an online web application scanner which crawls through the app and discovers the vulnerabilities in the application. It attempts to find out the common web vulnerabilities like XSS, SQL Injection and all the way down to web app fingerprinting.

As per their FAQ it takes around half an hour to scan normal sized websites, but as soon as I initiated scan for my website, I got a notification mail saying that it takes around 72 hours to complete the scan but I got the results emailed in about 5 hours.

Its very rare to find out a good n effective web application security assessment tool and would make it almost impossible if you want it for free. After a long time of hunt, I found one; CAT – Context App Tool. Although its free, it offers a good GUI and powerful features along with the basic ones which comes with a every proxy available.

Features

There are a number of features which CAT has to enable a wide variety of testing to be conducted:

• Request Repeater – Used for repeating a single request
• Proxy – Classic Inline proxy
• Fuzzer – Allows for batch of tests to be sent to a server for brute forcing, parameter fuzzing, forced browsing etc.
• Log – View a list of requests to sort, search repeat etc. Allows for a sequence of requests to be repeated and modified.
• Authentication Checker – Two synchronised proxies which can be used to check authentication and authorisation controls.
• SSL Checker – Request a specific page with various SSL ciphers and versions.
• Notepad – A text/RTF editor which can be used as a scratch pad for conversions etc.
• Web Browser – An integrated web browser with proxy pre-configured based on the Internet Explorer’s rendering engine.

Reasons to use CAT

There are a number of differences between CAT and currently available web proxies. Some key differences are:

• Uses Internet Explorer’s rendering engine for accurate HTML representation
• Supports many different types of text conversions including: URL, Base64, Hex, Unicode, HTML/XML, SQL and JavaScript no Quotes
• Integrated SQL Injection and XSS Detection
• Synchronised Proxies for Authentication and Authorisation checking
• Faster due to HTTP connection caching
• SSL Version and Cipher checker using OpenSSL
• Greater flexibility for importing/exporting logs and saving projects
• Tabbed Interface allowing for multiple tools at once e.g. multiple repeaters and different logs
• The ability to repeat and modify a sequence of requests (particularly useful in SSO testing)
• Free!
