CVE-2024-7898Network attack vector

Unauthenticated backend access via default credentials

Published Aug 17, 2024 · Updated Aug 19, 2024

Use of default credentials in the backend of TOSEI Online Store Management System 4.02 through 4.04 allows remote attackers to gain access. The public record identifies the backend as the affected locus but does not disclose the credential values, login endpoint, or credential-validation logic. No prior authentication or user interaction is required; successful use exposes web management functions for operational data and remote machine control.
