phpMyAdmin through 5.2.3 CSRF Token Bypass via Non-AJAX POST to /sql

Summary

phpMyAdmin through 5.2.3 contains a cross-site request forgery vulnerability that allows remote attackers to execute arbitrary SQL by bypassing CSRF token checks on non-AJAX POST requests. Attackers can lure authenticated victims into submitting cross-site POSTs carrying sql_query to /sql or /database/sql, running SQL with the victim's database privileges under http or config authentication.
