Be mindful that many of us use PHPmyadmin to administer mySQL or postgre on our RHEL/Ubuntu servers. I’ve already updated all of my web server security protocols.
True, but that should be locked down? For remote access to sensitive services I use a ssh tunnel to the internal private network, things like MySQL are open only to that network, which allows me to e.g. securely replicate an offsite backup, or if I chose, to run phpMyadmin on my local machine (but there are better tools when you have wire access.) Well, this assumes you control the hardware, or at least ssh access. Not often the case.
