Description

DataEase is an open-source data visualization and analytics platform. Versions 2.10.20 and below contain a SQL injection vulnerability in the /datasource/getTableField endpoint. The getTableFiledSql method in CalciteProvider.java incorporates the tableName parameter directly into SQL query strings using String.format without parameterization or sanitization. Although DatasourceServer.java validates that the table name exists in the datasource, an attacker can bypass this by first registering an API datasource with a malicious deTableName, which is then returned by getTables and passes the validation check. An authenticated attacker can execute arbitrary SQL commands, enabling error-based extraction of sensitive database information. This issue has been fixed in version 2.10.21.
