Some advice (assuming the culprit here is phpMyAdmin):
- Keep phpMyAdmin up to date. Best way to do this is to use a
package from a well known repository like EPEL that keeps the
package at the latest version for you.
- Run with SELinux Enforcing
- Protect phpMyAdmin with Basic HTTP authentication instead of
relying only on phpMyAdmin's authentication which does nothing to
prevent the exploitation of many URL-based vulnerabilities.
