DHIS2 Core contains the service layer and Web API for DHIS2, an information system for data capture. Starting in the 2.35 branch and prior to versions 2.36.13, 2.37.8, 2.38.2, and 2.39.0, when the Category Option Combination Sharing settings are configured to control access to specific tracker program events or program stages, the /trackedEntityInstances and /events API endpoints may include all events regardless of the sharing settings applied to the category option combinations. When this specific configuration is present, users may have access to events which they should not be able to see based on the sharing settings of the category options. The events will not appear in the user interface for web-based Tracker Capture or Capture applications, but if the Android Capture App is used they will be displayed to the user. Versions 2.36.13, 2.37.8, 2.38.2, and 2.39.0 contain a fix for this issue. No workaround is known.

Weakness

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Extended Description

Access control involves the use of several protection mechanisms such as:

When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
