C97net qEngine CMS through 6.0.0, Kemana Directory through 1.5.6, and Cart Engine through 3.0.0 contain an information disclosure vulnerability that exposes database backups in the web-accessible /admin/backup directory. Unauthenticated attackers can list the directory or guess date-based names like Full Backup YYYYMMDD.sql to download dumps containing user records and administrator password hashes.
A backup file is stored in a directory or archive that is made accessible to unauthorized actors.
