[suggested description]
Zzzcms has a logical flaw. The backup file path when restoring the database backup file is controllable, and you can upload your own forged malicious database backup file. As a result, attackers can use this vulnerability to modify the passwords of other users without permission, destroy the site database structure, and even cause the site to crash. Or even Use sql statements to create php Trojans when knowing the physical path, resulting in getshell
