DHIS2 is a flexible information system for data capture, management, validation, analytics and visualization. A SQL injection vulnerability was identified in the SqlView API endpoint of the DHIS2 application in the "filter" parameter used by the "/api/sqlViews/{viewId}/data.json" endpoint. An authenticated user with access to a SqlView can inject arbitrary SQL queries inside the "filter" parameter by abusing an expression executed by PostgreSQL and its output is reflected inside the application error message. This behavior enables attackers to extract arbitrary database content using error-based SQL injection.
