Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Joomla is the second popular CMS for a website with more than 4.5% of market share and growing.

Security is as important as website design and content, but we often ignore this until negatively impacted. Not correctly configured/hardened Joomla server can be vulnerable to many including remote code execution, SQL Injection, Cross-Site Scripting, Information leakage, etc.

Security is a process cycle, which one should always perform against web applications. In this article, I will talk about tools to scan the Joomla website for vulnerability to protect from evil.

Hacker Target

Joomla security scan by Hacker Target has two options.


Passive scan – this is a FREE scan, and it does the following.

  • Google safe browsing look-up
  • Directory index lookup
  • External link and their web reputation
  • List of external iFrames, JavaScript
  • Geolocation & web hosting lookup

Aggressive, active scan – this requires membership and check aggressively to detect known exploits and vulnerabilities in themes, extensions, modules, components & Joomla core.


SiteGuarding is a cloud-based website security scanner which also provides Joomla extension to analyze your website.

In the FREE version of the extension, you get the following.

  • Scan up to 500 files
  • Daily virus database update
  • Reporting
  • One scan per day
  • Heuristic logic

You may also want to try their Antivirus Scanner extension.


Detectify is an enterprise-ready SaaS scanner for comprehensive website auditing with more than 1000 vulnerabilities including OWASP top 10. It does security checks on CMS like Joomla, WordPress, Drupal, etc. to ensure CMS specific vulnerabilities are covered.


It is not entirely free but you can avail their trial offer to see how it works.


JAMSS (Joomla Anti Malware Scan Script) is a script that you got to install on your website root location.

Script installation is nothing but uploading the file jamss.php common to your webroot. JAMSS identifies typical fingerprints, traces that could have been compromised. The script doesn’t harm anything and to access the scan report; you just access


Site Check by SUCURI check for known malware, blacklisting, SPAM, defacement and give you information on a web server, links & included scripts.


Security Check

Security Check extension protects your website for more than 90 attacks pattern, and it has an inbuilt vulnerability check to test installed extensions for any security risk.


Joomscan is one of the most popular open-source tools to help you in finding known vulnerabilities of Joomla Core, Components, and SQL Injection, Command execution. There are two ways you can get this running.

  • Download from OWASP site and install on your PC
  • Use Kali Linux which comes with more than 600 tools including Joomscan

Once you have Joomscan installed, here is how you can run it on the Joomla site to scan the vulnerability.

./joomscan –u

Ex, I executed my test site.

root@Chandan:~# joomscan -oh -u
