Cross-Site Scripting (XSS) Vulnerability in HAPI FHIR Testpage Overlay Module

CVE-2019-12741 · MEDIUM Severity

AV:N/AC:M/AU:N/C:N/I:P/A:N

XSS exists in the HAPI FHIR testpage overlay module of the HAPI FHIR library before 3.8.0. The attack involves unsanitized HTTP parameters being output in a form page, allowing attackers to leak cookies and other sensitive information from ca/uhn/fhir/to/BaseController.java via a specially crafted URL. (This module is not generally used in production systems so the attack surface is expected to be low, but affected systems are recommended to upgrade immediately.)
