Adminer is a popular PHP database management tool. This blog post will detail its vulnerabilities, how to exploit them and how to protect yourself from these risks. RCE using SQLite Versions 4.2.4 and before that support SQLite are vulnerable to this. The server must have the SQLite PHP driver installed for this to work.
