CyberRota Analysis
AI-GeneratedThe HAPI FHIR implementation in Java is vulnerable to XML External Entity (XXE) injection due to improper configuration of the TransformerFactory, allowing attackers to exploit transformed XML for local file disclosure and potentially trigger server-side request forgery (SSRF). Organizations using versions prior to 6.9.10 should prioritize updating to the latest version to mitigate the risk of unauthorized data access and system compromise. This vulnerability is particularly critical for healthcare providers and software developers utilizing HAPI FHIR for interoperability.

Original NVD Description
HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.10, org.hl7.fhir.utilities.XsltUtilities saxonTransform(...) overloads instantiated a bare net.sf.saxon.TransformerFactoryImpl() without ACCESS_EXTERNAL_DTD or ACCESS_EXTERNAL_STYLESHEET restrictions, allowing an attacker who controls or can tamper with transformed XML to trigger XML External Entity injection for local file disclosure and blind XXE or SSRF to arbitrary URLs reachable from the host. This issue is fixed in version 6.9.10.
