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.

• 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.
