Vulnerability details
DHIS2 Core contains the service layer and Web API for DHIS2, an information system for data capture. Starting in the 2.36 branch and prior to versions 2.37.9.1, 2.38.3.1, and 2.39.1.2, using object model traversal in the payload of a PATCH…

request, authenticated users with write access to an object may be able to modify related objects that they should not have access to. DHIS2 implementers should upgrade to a supported version of DHIS2 to receive a patch: 2.37.9.1, 2.38.3.1, or 2.39.1.2. It is possible to work around this issue by blocking all PATCH requests on a reverse proxy, but this may cause some issues with the functionality of built-in applications using legacy PATCH requests.

Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Requiring prior authorization for each remote access type prevents improper access control over remote connections.
Requiring authorization of wireless access before allowing connections enforces proper access control for this access method.
Requiring authorization and configuration controls for mobile device connections directly enforces access control and prevents unauthorized devices from reaching organizational systems.
Defining account types, requiring approvals for creation, specifying authorizations, monitoring usage, and reviewing accounts directly prevents improper access control by ensuring only authorized accounts exist and are used.
Enforces rules governing access to the system and its data from external systems based on established trust relationships.
