Descriptions

expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE.

expat 2.1.0 y anteriores no maneja adecuadamente entidades de expansión a menos que un desarrollador de aplicaciones use la función XML_SetEntityDeclHandler, esto permite a atacantes remotos provocar una denegación de servicio (consumo de recursos), enviar peticiones HTTP a los servidores de la intranet, o leer archivos arbitrarios a través de un documento XML manipulado, también conocido como problema XML External Entity (XXE) NOTA: se podría argumentar que debido a que expat ya ofrece la posibilidad de desactivar la expansión entidad externa, la responsabilidad de la solución de este problema se encuentra con los desarrolladores de aplicaciones, de acuerdo con este argumento, esta entrada debe ser rechazada, y cada aplicación afectada tendría su propio CVE .
