CVE-2019-3911

Name of the Vulnerable Software and Affected Versions LabKey Server Community Edition versions prior to 18.3.0-61806.763

Description A reflected cross-site scripting issue allows an unauthenticated remote attacker to inject arbitrary javascript. This is achieved via the onerror parameter in the "/ r2/query" endpoint.

Recommendations For versions prior to 18.3.0-61806.763, update to version 18.3.0-61806.763 or later to resolve the issue. As a temporary workaround, consider restricting access to the "/ r2/query" endpoint to minimize the risk of exploitation. Avoid using the onerror parameter in the affected endpoint until the issue is resolved.
