Title
XXE vulnerability in XSLT parsing in `org.hl7.fhir.publisher`
Summary
The HL7 FHIR IG publisher is a tool to take a set of inputs and create a standard FHIR IG. Prior to version 1.7.4, 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. This impacts use cases where org.hl7.fhir.publisher is being used to within a host where external clients can submit XML. A previous release provided an incomplete solution revealed by new testing. This issue has been patched as of version 1.7.4. No known workarounds are available.
Severity
8.6 (High)

CVE-2024-52800 (GCVE-0-2024-52800)

Title
Potential XXE (XML External Entity Injection) vulnerability in veraPDF CLI
Summary
veraPDF is an open source PDF/A validation library. Executing policy checks using custom schematron files via the CLI invokes an XSL transformation that may theoretically lead to a remote code execution (RCE) vulnerability. This doesn't affect the standard validation and policy checks functionality, veraPDF's common use cases. Most veraPDF users don't insert any custom XSLT code into policy profiles, which are based on Schematron syntax rather than direct XSL transforms. For users who do, only load custom policy files from sources you trust. This issue has not yet been patched. Users are advised to be cautious of XSLT code until a patch is available.

Title
XXE vulnerability in XSLT parsing in `org.hl7.fhir.core`
Summary
HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. XSLT parsing 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. This is related to GHSA-6cr6-ph3p-f5rf, in which its fix (#1571 & #1717) was incomplete. This issue has been addressed in release version 6.4.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

CVE-2024-49704 (GCVE-0-2024-49704)

Vulnerability from cvelistv5 – Published: 2024-12-10 13:53 – Updated: 2024-12-10 15:10
VLAI
Summary
A vulnerability has been identified in COMOS V10.3 (All versions < V10.3.3.5.8), COMOS V10.4.0 (All versions), COMOS V10.4.1 (All versions), COMOS V10.4.2 (All versions), COMOS V10.4.3 (All versions < V10.4.3.0.47), COMOS V10.4.4 (All versions < V10.4.4.2), COMOS V10.4.4.1 (All versions < V10.4.4.1.21). The Generic Data Mapper, the Engineering Adapter, and the Engineering Interface improperly handle XML External Entity (XXE) entries when parsing configuration and mapping files. This could allow an attacker to extract any file with a known location on the user's system or accessible network folders by persuading a user to use a maliciously crafted configuration or mapping file in one of the affected components.

Mitigation
Implementation System Configuration

Many XML parsers and validators can be configured to disable external entity expansion.

CAPEC-221: Data Serialization External Entities Blowup

This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
