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

Manual Penetration Testing with Proxy

Web browser Attack Proxy Target

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

Selenium + OWASP ZAP + Nessus + SSLyze + Internal security tools

OWASP ZAP

OWASP ZAP - Simple scan

zap-cli quick-scan --self-contained --start-options '-config api.disablekey=true' http://127.0.0.1/

zap-cli --api-key coeoobt6fof9k4g3iajshtnp7v quick-scan --self-contained --spider -r http://127.0.0.1/

* API key could be found in ~/.ZAP/config.xml of current user.

OWASP ZAP - Simple scan with ZAPR

zapr --debug --summary http://127.0.0.1

OWASP ZAP - Running as a daemon

/opt/zaproxy/zap.sh -daemon -host 0.0.0.0 -port 8480

Also, Docker usage possible : https://github.com/zaproxy/zaproxy/wiki/Docker

OWASP ZAP - Plugins management

Install all plugins, take some time :

su jenkins /opt/zaproxy/zap.sh -daemon -host 0.0.0.0 -port 8480 -addoninstallall

Install selected plugin :

su jenkins /opt/zaproxy/zap.sh -daemon -host 0.0.0.0 -port 8480 -addoninstall exportreport

* Plugins will be installed in the ~/.ZAP folder of user, who launches ZAP.** Plugins keys could be found here :

https://github.com/zaproxy/zap-extensions/releases

OWASP ZAP

https://github.com/zaproxy/zaproxy/wiki/Docker

zap.sh -daemon -host 0.0.0.0 -port 8480

zap-x.sh -daemon -host 0.0.0.0 -port 8080

zap-cli quick-scan --self-contained \ --start-options '-config api.disablekey=true' http://target
