"The phpMyAdmin development team reports : Summary XSS in Designer
feature Description A Cross-Site Scripting vulnerability was found in
the Designer feature, where an attacker can deliver a payload to a
user through a specially crafted database name. Severity We consider
this attack to be of moderate severity. Summary File inclusion and
remote code execution attack Description A flaw has been discovered
where an attacker can include (view and potentially execute) files on
the server.

The vulnerability comes from a portion of code where pages are
redirected and loaded within phpMyAdmin, and an improper test for
whitelisted pages.

An attacker must be authenticated, except in these situations :

- $cfg['AllowArbitraryServer'] = true: attacker can specify any host
he/she is already in control of, and execute arbitrary code on
phpMyAdmin

- $cfg['ServerDefault'] = 0: this bypasses the login and runs the
vulnerable code without any authentication Severity We consider this
to be severe. Mitigation factor Configuring PHP with a restrictive
`open_basedir` can greatly restrict an attacker's ability to view
files on the server. Vulnerable systems should not be run with the
phpMyAdmin directives $cfg['AllowArbitraryServer'] = true or
$cfg['ServerDefault'] = 0"
