12 Open Source Web Security Scanner to Find Vulnerabilities

12 Open Source Web Security Scanner to Find Vulnerabilities

An interesting report by Symantec reveals, 76% of scanned websites had malware.

and if you are using WordPress then in another report by SUCURI shows, more than 70% of scanned websites were infected with one or more vulnerabilities.

As a web application owner, how do you ensure your site is protected from online threats? Doesn’t leak sensitive information?

If you are using cloud-based security solution then most likely regular vulnerability scanning is part of the plan. However, if not then you got to perform a routine scan and take necessary action to mitigate the risks.

There are two types of scanner.

Commercial – give you an option to automate the scanning for continuous security, reporting, alerting, detailed mitigation instructions, etc. Some of the known names in the industry are:

  • Acunetix
  • Detectify
  • Qualys

Open Source/Free – you can download and perform security scan on-demand. Not all of them will be able to cover a broad range of vulnerabilities like a commercial one.

Let’s check out the following open source web vulnerability scanner.

1. Arachni

Arachni, a high-performance security scanner built on Ruby framework for modern web applications. It is available in portable binary for Mac, Windows & Linux.

Not just basic static or CMS website but Arachni is capable of doing following platform fingerprints. It performs active & passive checks, both.

  • Windows, Solaris, Linux, BSD, Unix
  • Nginx, Apache, Tomcat, IIS, Jetty
  • Java, Ruby, Python, ASP, PHP
  • Django, Rails, CherryPy, CakePHP, ASP.NET MVC, Symfony

Some of the vulnerabilities detection are:

  • NoSQL/Blind/SQL/Code/LDAP/Command/XPath injection
  • Cross-site request forgery
  • Path traversal
  • Local/Remote File inclusions
  • Response splitting
  • Cross-site scripting
  • Unvalidated DOM redirects
  • Source code disclosure

You have an option to take an audit report in HTML, XML, Text, JSON, YAML, etc.

Arachni let you extend the scan to the next level by leveraging plugins. Check out the complete Arachni features and download to experience it.

2. XssPy

A python based XSS (cross-site scripting) vulnerability scanner is used by many organization including Microsoft, Stanford, Motorola, Informatica, etc.

XssPy by Faizan Ahmad is a smart tool. It does one thing ut pretty well. Instead of just checking the home page or given page it checks the entire link on the websites.

XssPy also checks the subdomain, so nothing is left out.

3. w3af

w3af, an open source project started back in late 2006 is powered by Python and available on Linux and Windows OS. w3af is capable of detecting more than 200 vulnerabilities including OWASP top 10.

w3af let you inject payloads to headers, URL, cookies, query string, post-data, etc. to exploit the web application for auditing. It supports various logging method for reporting. Ex:

Ex:

  • CSV
  • HTML
  • Console
  • Text
  • XML
  • Email

It’s built on a plugin architecture, and you can check out all the plugins available here.

4. Nikto

An open-source project sponsored by Netsparker aim to find web server misconfiguration, plugins and web vulnerabilities. Nikto perform the comprehensive test against over 6500 risk items.

It supports HTTP proxy, SSL, with or NTLM authentication, etc. and can define maximum execution time per target scan.

Nikto is also available in Kali Linux.

It looks promising for intranet solution to find web servers security risks.

5. Wfuzz

Wfuzz (The Web Fuzzer) is an application assessment tool for penetration testing. You can fuzz the data in HTTP request for any field to exploit the web application and audit the web applications.

Wfuzz required having Python installed on the computer where you want to run the scan from. It got excellent documentation for you to get it started.

6. OWASP ZAP

ZAP (Zet Attack Proxy) is one of the famous penetration testing tools which is actively updated by hundreds of volunteer worldwide.

It’s cross-platform java based tool which can run even on Raspberry Pi. ZIP sits between browser and web application to intercept and inspect messages

Some of the following are worth mentioning ZAP’s functionality.

  • Fuzzer
  • Automated & passive scanner
  • Supports multiple scripting languages
  • Forced browsing

I would highly recommend to check out OWASP ZAP tutorial videos to get it started.

7. Wapiti

Wapiti scans the web pages of given target and looks for scripts and form to inject the data to see if that is vulnerable. It is not a source code security checks instead it perform black-box scans.

It supports GET and POST HTTP method, HTTP and HTTPS proxies, several authentications, etc.

8. Vega

Vega is developed by Subgraph, a multi-platform supported tool written in Java to find XSS, SQLi, RFI and many other vulnerabilities.

Vega got nice GUI and capable of performing an automated scan by logging into an application with given credential.

If you are a developer, you can leverage vega API to create new attack modules.

9. SQLmap

As you can guess by the name, with the help of the sqlmap you can perform penetration testing on a database to find flaws.

It works with Python 2.6 or 2.7 on any OS. If you are looking to find SQL injection and exploit the database, then sqlmap would be helpful.

10. Grabber

It’s small tool based on Python and does few things quite well. Some of the Grabber’s features are:

  • JavaScript source code analyzer
  • Cross-site scripting, SQL injection, Blind SQL injection
  • PHP application testing using PHP-SAT

11. Golismero

A framework to manage and run some of the popular security tools like Wfuzz, DNS recon, sqlmap, OpenVas, robot analyzer, etc.).

Golismero is smart, it can consolidated test feedback from other tool and merge to show a single result.

12. OWASP Xenotix XSS

Xenotix XSS by OWASP is an advanced framework to find and exploit cross-site scripting. It got inbuilt three intelligent fuzzers for a fast scan and improved results.

It got hundreds of features, and you can check out all listed here.

Web security is critical to an online business, and I hope above listed free/open source vulnerability scanner helps you to find risk so you can mitigate before someone take advantage of it.
