Public on

Last Modified: UTC

Description

A flaw was found in HAPI FHIR - HL7 FHIR Core Artifacts. eXtensible Stylesheet Language Transformations (XSLT) transforms performed by various components are vulnerable to XML external entity injections. A processed XML file with a malicious DTD tag could produce XML containing data from the host system.

Statement

This vulnerability is of important severity rather than moderate due to its potential to expose sensitive host data and compromise system integrity. By exploiting the XXE vulnerability, an attacker can read arbitrary files (e.g., `/etc/passwd`), perform Denial of Service (DoS) through resource exhaustion, or even execute further attacks by leveraging accessible information.

Common Vulnerability Scoring System (CVSS) Score Details

Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
