CVE-2022-41947 Information

Description

DHIS 2 is an open source information system for data capture management validation analytics and visualization. Through various features of DHIS2 an authenticated user may be able to upload a file which includes embedded javascript. The user could then potentially trick another authenticated user to open the malicious file in a browser which would trigger the javascript code resulting in a cross-site scripting (XSS) attack. DHIS2 administrators should upgrade to the following hotfix releases: 2.36.12.1 2.37.8.1 2.38.2.1 2.39.0.1. Users unable to upgrade may add the following simple CSP rule in your web proxy to the vulnerable endpoints: script-src 'none'. This workaround will prevent all javascript from running on those endpoints.
