Description

DataEase is an open-source data visualization and analytics platform. Versions 2.10.20 and below contain a SQL injection vulnerability in the API datasource update process. When a new table definition is added during a datasource update via /de2api/datasource/update, the deTableName field from the user-submitted configuration is passed to DatasourceSyncManage.createEngineTable, where it is substituted into a CREATE TABLE statement template without any sanitization or identifier escaping. An authenticated attacker can inject arbitrary SQL commands by crafting a deTableName that breaks out of identifier quoting, enabling error-based SQL injection that can extract database information. This issue has been fixed in version 2.10.21.

• CWE-89Improper Neutralization of Special Elements used in an SQL CommandThe product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
