Description

DataEase is an open-source data visualization and analytics platform. Versions 2.10.20 and below contain a SQL injection vulnerability in the orderDirection parameter used in dataset-related endpoints including /de2api/datasetData/enumValueDs and /de2api/datasetTree/exportDataset. The Order2SQLObj class directly assigns the raw user-supplied orderDirection value into the SQL query without any validation or whitelist enforcement, and the value is rendered into the ORDER BY clause via StringTemplate before being executed against the database. An authenticated attacker can inject arbitrary SQL commands through the sorting direction field, enabling time-based blind data extraction and denial of service. 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.
