Detailsinfo

A vulnerability was found in DHIS2 up to 2.43.0. It has been declared as critical. Affected by this vulnerability is an unknown part of the file api/sqlViews/data.json of the component SqlView API endpoint. The manipulation of the argument filter 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. The summary by CVE is:

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. Affected versions include: 2.37, 2.38, 2.39, 2.40.x before 2.40.11.1/2.40.12, 2.41.x before 2.41.8.2, 2.42.x before 2.42.5.1, 2.43.0 before 2.43.0.1, 2.44 development branch before PR #24162 Patched versions include: 2.37-EOS (2026-06-09), 2.38-EOS (2026-06-09), 2.39-EOS (2026-06-09), 2.40.11.1, 2.40.12, 2.41.8.2, 2.42.5.1, 2.43.0.1, 2.44 development branch after PR #24162
