Unauthenticated file deletion via mysql deletion route

Published Dec 27, 2021 · Updated Aug 4, 2024

Path traversal in Qibosoft v7 allows remote attackers to delete arbitrary files through the mysql deletion action in /admin/index.php. The public record identifies the lfj=mysql&action=del route but does not disclose the file-name parameter, validation failure, or deletion call. No authentication or user interaction is required, and deletion of application or host files can corrupt data or interrupt the service.
