Vulnerability Title
DataEase has SQL Injection via Datasource Save Flow
Source: CVE Program / CVE List V5
Vulnerability 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 saving process. The deTableName field from the Base64-encoded datasource configuration is used to construct a DDL statement via simple string replacement without any sanitization or escaping of the table name. 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 such as the MySQL version. This issue has been fixed in version 2.10.21.
