CVE-2022-4280Public exploitNetwork attack vector

User information disclosure via findUser endpoint

Published Dec 3, 2022 · Updated Apr 15, 2025

Information disclosure in Dot Tech Smart Campus System allows remote attackers to obtain user data through /services/Card/findUser. The public record names this endpoint but does not disclose the manipulated request field or how its authorization logic returns user data. Published assessments disagree on whether authentication is required; the reported consequence is read-only disclosure with no integrity or availability impact.
