CVE-2023-2903Public exploitNetwork attack vector

Role-data disclosure via unguarded GetGridJson endpoint

Published May 25, 2023 · Updated Aug 2, 2024

Improper access control in NFine Rapid Development Platform 20230511 allows remote authenticated users to read role data through GetGridJson. The /SystemManage/Role/GetGridJson handler accepts a crafted role-list request and returns data without enforcing the caller's role authorization. Low-privilege application access is required, and the documented consequence is disclosure of role records without data modification or service interruption.
