CVE-2024-45294
XXE vulnerability in XSLT transforms in `org.hl7.fhir.core`
Impact
### Impact XSLT transforms performed by various components are vulnerable to XML external entity injections. A processed XML file with a malicious DTD tag ( `<!DOCTYPE foo [<!ENTITY example SYSTEM "/etc/passwd"> ]>` could produce XML containing data from the host system. This impacts use cases where org.hl7.fhir.core is being used to within a host where external clients can submit XML. ### Patches This issue has been patched in release 6.3.23 ### Workarounds None. ### References [MITRE CWE](https://cwe.mitre.org/data/definitions/611.html) [OWASP XML External Entity Prevention Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html#transformerfactory)
