CVE-2021-43362Network attack vector

Unauthenticated data extraction via SQL injection

Published Sep 29, 2022 · Updated May 20, 2025

SQL injection in MedData HBYS before 1.1 allows remote attackers to extract sensitive hospital data through its web interface. Public records attribute the flaw only to improper input sanitization and do not identify the affected endpoint, parameter, query-building locus, or exact handling error. No authentication is required, and the reported consequence is disclosure of critical information stored in the hospital system.
