description

DataEase versions through 2.10.27 do not consistently enforce authentication for a standalone static-resource upload endpoint. A remote attacker who can reach that endpoint may upload files without authorization.

mitigation

Upgrade DataEase to version 2.10.28 or later. Until the upgrade is complete, disable or restrict network access to the standalone static-resource upload endpoint and enforce authentication upstream.
