CVE-2022-4984Known exploitationNetwork attack vector

Unauthenticated data disclosure via login SQL injection

Published Nov 13, 2025 · Updated Nov 13, 2025

SQL injection in ZenTao Biz before 6.5, Max before 3.0, and Open Source Edition before 16.5 allows remote attackers to read backend data. The unauthenticated /zentao/user-login.html handler uses the account parameter in a database query without proper validation, allowing crafted SQL expressions to alter the query. Reaching the login endpoint is sufficient; successful exploitation discloses user and application data without reported write or service-interruption impact.
