About this workshop ● Duration 2 hours ● 100% open source powered ● Intermediate technical level required ● Oriented Developers / QA / Operations / CTO / ... ● Interactive, study-oriented ... 

Workshop content ● Theoretical part ● Introduction to Web security ○ Major security risks ○ Pentesting types ● Insecure code ● Drupalxploitable project ● Practical part ● Vulnerable site create / study ● Manual security testing with scanners ● Manual security testing using Zed Attack Proxy GUI ● Automated security testing 

Introduction in Web Security 

Major Risks 

Pentesting methods - Black-box ● We don't know what is inside ● Testing as an external user 

Pentesting methods - Grey-box ● We have advanced access to the project 

Pentesting methods - White-box ● We know all about the project ● We have the access to the project code 

Manual Penetration Testing Scanner Target 

Manual Penetration Testing with Proxy Web browser Attack Proxy Target 

Automating Penetration Testing Web browser Attack Proxy Target Security Framework CI Bugtraceker

How to write (in)secure code for Drupal 8 

Current situation for Drupal 8 ● https://www.drupal.org/docs/8/security/writing-secure-code-for-drupal-8 a. Sanitizing on output to avoid Cross Site Scripting (XSS) attacks : t(), Html::escape Xss::filter() or Xss::filterAdmin() b. Checking URLs UrlHelper::stripDangerousProtocols(), UrlHelper::filterBadProtocol(), SafeMarkup::format(). c. Use the database abstraction layer to avoid SQL injection attacks 

Bad code example - SQL Injection db_query('SELECT foo FROM {table} t WHERE t.name = '. $_GET['user']); Exploit example : https://www.exploit-db.com/exploits/34993/ 

Bad code example - XSS exploits - --- modules/system/system.admin.inc 2013-04-03 17:29:52.000000000 -0400 +++ modules/system/system.admin.inc 2013-08-07 10:47:29.277279676 -0400 @@ -979,10 +979,10 @@ function _system_modules_build_row($info ); // Set the basic properties. $form['name'] = array( - - '#markup' => $info['name'], + '#markup' => check_plain($info['name']), ); $form['description'] = array( - - '#markup' => t($info['description']), + '#markup' => t("@desc", array('@desc' => $info['description'])), ); $form['version'] = array( '#markup' => $info['version'], http://seclists.org/fulldisclosure/2013/Aug/158 

There are much more risks ... SQL, HTML, iFrame, SSI, OS Command, PHP, XML, XPath, LDAP, Host Header and SMTP injections Cross-Site Scripting (XSS), Cross-Site Tracing (XST) and Cross-Site Request Forgery (CSRF) AJAX and Web Services issues (jQuery/JSON/XML/SOAP/WSDL) Authentication, authorization and session issues, file upload flaws and backdoor files Arbitrary file access, directory traversals, local and remote file inclusions (LFI/RFI) Configuration issues: Man-in-the-Middle, cross-domain policy files, information disclosures,... HTTP parameter pollution, HTTP response splitting and HTTP verb tampering Insecure DistCC, FTP, NTP, Samba, SNMP, VNC and WebDAV configurations HTML5 ClickJacking, Cross-Origin Resource Sharing (CORS) and web storage issues XML External Entity attacks (XXE) and Server Side Request Forgery (SSRF) Heartbleed and Shellshock vulnerability (OpenSSL), Denial-of-Service (DoS) attacks Parameter tampering, cookie and password reset poisoning ... 

Drupalxploitable 

About Drupalxploitable ● Purposefully vulnerables Drupal installation ● Basically : “a very crappy Drupal site” ● Open source (github) 

Existing projects in PHP world Damn Vulnerable Web Application (DVWA) http://www.dvwa.co.uk/ Mutillidae http://www.irongeek.com/i.php?page=mutillidae/mutillidae-deliberately-vulnerable-php-owasp-top-10 WebGoatPHP https://github.com/shivamdixit/WebGoatPHP buggy web application http://www.itsecgames.com/ 

And even standalone distribution Metasploitable https://sourceforge.net/projects/metasploitable/ 

Practical part
