Description
================================================================================
The userpro plugin has the ability to bypass login authentication for the user
'admin'. If the site does not use the standard username 'admin' it is not affected.

1 - Google Dork inurl:/plugins/userpro

You are now logged in with full administrator access.

Keyboard yang saya pakai mempunyai backlit (Pencahayaan) yang dapat dinyalakan dan dimatikan menggunakan tombol Scroll Lock. Ketika saya pakai di Windows, tidak ada masalah sama sekali, tapi ketika saya migrasi OS ke Ubuntu, tombol Scroll Lock tersebut tidak mau bekerja. Setelah saya membaca referensi dari Google, ternyata bukan hanya saya, sudah banyak pengguna Ubuntu yang mengalami kejadian serupa.
