Vulnerability Title
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in dhis2-core
Source: CVE Program / CVE List V5
Vulnerability Description
DHIS 2 is an information system for data capture, management, validation, analytics and visualization. A SQL injection security vulnerability has been found in specific versions of DHIS2. This vulnerability affects the /api/trackedEntityInstances API endpoint in DHIS2 versions 2.34.4, 2.35.2, 2.35.3, 2.35.4, and 2.36.0. Earlier versions, such as 2.34.3 and 2.35.1 and all versions 2.33 and older are unaffected. The system is vulnerable to attack only from users that are logged in to DHIS2, and there is no known way of exploiting the vulnerability without first being logged in as a DHIS2 user. A successful exploit of this vulnerability could allow the malicious user to read, edit and delete data in the DHIS2 instance. There are no known exploits of the security vulnerabilities addressed by these patch releases. However, we strongly recommend that all DHIS2 implementations using versions 2.34, 2.35 and 2.36 install these patches as soon as possible. There is no straightforward known workaround for DHIS2 instances using the Tracker functionality other than upgrading the affected DHIS2 server to one of the patches in which this vulnerability has been fixed. For implementations which do NOT use Tracker functionality, it may be possible to block all network access to POST to the /api/trackedEntityInstance endpoint as a temporary workaround while waiting to upgrade.
