phpMyAdmin is a free, open-source tool for administering MySQL and MariaDB. It is widely used to manage databases of websites created with WordPress, Joomla, and other content management platforms.
Recently, a security researcher Manuel Garcia Cardenas disclosed a cross-site request forgery (CSRF) vulnerability (CVE-2019-12922) in phpMyAdmin. An attacker can exploit this vulnerability to trick an authenticated user into performing malicious operations. Specifically, the attacker first crafts a malicious URL and sends it to the targeted web administrator, who has logged in to the phyMyAdmin panel on the same browser. If the administrator clicks this link, the malicious request contained in the URL will be unknowingly executed, leading to deletion of any server configured on the setup page of the phyMyAdmin panel on the victim’s server.
