CVE-2020-18019Public exploitNetwork attack vector

Database disclosure via unneutralized typeid SQL input

Published Apr 28, 2021 · Updated Aug 4, 2024

SQL injection in Xinhu OA System 1.8.3 allows remote attackers to read sensitive database data through a crafted typeid parameter. The createfolderAjax function in mode_worcAction.php passes typeid into a database query without neutralizing SQL syntax, enabling blind SQL injection. No authentication or user interaction is required, and the published exploit uses sqlmap to enumerate databases through the network-facing request.
