For our tenth security review of a plugin based on the voting of our customers, we reviewed the plugin Really Simple SSL.

If you are not yet a customer of the service you can currently try it free for your first month and then start suggesting and voting on plugins to get security reviews after your first payment for the service. For those already using the service that haven’t already suggested and voted for plugins you can start doing that here.

The review was done on version 2.5.11  of Really Simple SSL. We checked for the following issues:

• Insecure file upload handling (this is the cause of the most exploited type of vulnerability, arbitrary file upload)
• Deserialization of untrusted data
• Security issues with functions accessible through WordPress’ AJAX functionality (those are a common source of disclosed vulnerabilities these days)
• Persistent cross-site scripting (XSS) vulnerabilities in publicly accessible portions of the plugin
• Cross-site request forgery (CSRF) vulnerabilities in the admin portion of plugins
• SQL injection vulnerabilities (the code that handles requests to the database)
• Reflected cross-site scripting (XSS) vulnerabilities
• Lack of protection against unintended direct access of PHP files

Results

We found no issues with any of the checked items in version 2.5.11 of Really Simple SSL.
