The following plugins were detected by reading the HTML source of the WordPress sites front page.

auto-thickbox-plus

Plugins are a source of many security vulnerabilities within WordPress installations, always keep them updated to the latest version available and check the developers plugin page for information about security related updates and fixes.

Warning User Enumeration is possible
The first two user ID’s were tested to determine if user enumeration is possible.

ID User Login
1 None admin
2 None admin2
It is recommended to rename the admin user account to reduce the chance of brute force attacks occurring. As this will reduce the chance of automated password attackers gaining access. However it is important to understand that if the author archives are enabled it is usually possible to enumerate all users within a WordPress installation.
