Did you took care of the previous ones?#@%




The PayPal / Magento integration flaw (by NBS)



NBS System will release a new vulnerability soon



Or even the one that were not Magento specific?#@%



PHP: two versions behind, really?

88% are outdated and not

supported anymore…

No security fixes.

(and +12% to +40%

performances to gain)

PHP versions in use, in our parc:

Easily exploitable things beyondclassical vulnerabilities

www.nbs-system.com



Magento Support giving dangerous advices

• “Chmod 777 your document root…” *REALLY* ?• “Magento is not compatible with Reverse proxies.” *Woot* ?• “Give me your root password so we can look” *NO KIDDING*?• Etc…

When Magento support is being creative…

Don’t go to a car dealer to fix a bad tooth…



Leaving your logs accessible, especially Debug one

Leaving payment gateway logs accessible to all

Not hiding Magento, PHP, Apache versions

Use a minimum of unaudited extensions, a lot are BAD

Weak passwords, along with no locking policies are a plague

Classical mistakes that cost…



Leaving import/export scripts, reindexers, crontabs accessible

Try calling pages that load very slowly

Access directly the API to import / export

Etc.

Applicative level D.o.S attacks

Securing Magento Flaws

www.nbs-system.com



Securing Magento flaws

• Update to versions CE > 1.9 or EE > 1.14.1• Use PHP 5.6• Shoplift, Magmi, XML-RPC-XEE : filter the access with a

.htaccess file (or an nginx rule)



Securing recent flaws

Example with Magmi (using Apache)

RewriteCond %{REQUEST_URI} ^/(index.php/)?magmi/ [NC]RewriteCond %{REMOTE_ADDR} !^192.168.0.1RewriteRule ^(.*)$ http://%{HTTP_HOST}/ [R=302,L]

Example with Magmi (using Nginx)

location ~* ^/(index.php/)?magmi {allow 192.168.0.1;deny all;location ~* .(php) {include fastcgi_params; } }



Protect your backoffice & updater

Example using Apache

<Location /wp-admin>AuthType BasicAuthName "Restricted Area"AuthUserFile /etc/apache2/access/htpasswdRequire valid-userOrder deny,allowAllow from [MY_IP]

Satisfy any</Location>

Then, just add a user:

htpasswd –c /etc/apache2/access/htpasswd [user]



Leveraging native Magento security

• Use HTTPS in Backoffice & order tunnels access• Change your backoffice default URL• Do *NOT* use a weak password (no « tommy4242 » is not safe)• Put some limits to number of failed login attempts• Put a password expiration time and change it every 3 months• Enforce use of case sensitive password• Disable email password recovery

Securing Web application

www.nbs-system.com



Organizational security

• Get a security review• Keep track of vulnerabilities on Magento ecosystem• Have serious passwords, change them every 3 months• Do not keep informations unless they are needed• Pick a PCI/DSS certified hosting company• Use 3D secure• Keep up to date versions of Magento & PHP



Infrastructure security

• Keep a daily backup• Use a WAF, NAXSI is opensource, free and stable• Put rate limits on your Reverse Proxies• Filter your outgoing trafic

It’s the job of your managed services provider.



Host level security

• Change default backoffice URL• Disable directory indexing• Have correct permissions : file=644, directory=755• No follow, no index on preprod• Use the best practices mentioned before

It’s the job of your managed services provider.
