Permissions, Privileges, and Access Controls
Hot or Not Clone has insufficient access control for producing and reading database backups, which allows remote attackers to obtain the administrator username and password via a direct request to control/backup/backup.php, which generates a backup/dump/backup.sql file that can be downloaded via a direct request to control/downloadfile.php.
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
