Detailsinfo

A vulnerability has been found in DataEase up to 2.10.20 and classified as critical. This vulnerability affects an unknown function of the component API. The manipulation of the argument deTableName with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. The 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.
