CVE-2024-8602

When the XML is read from the codes in the PDF and parsed using a DocumentBuilder, the default settings of the DocumentBuilder allow for an XXE (XML External Entity) attack. Further information on this can be found on the website of the Open Worldwide Application Security Project (OWASP). An attacker could theoretically leverage this by delivering a manipulated PDF file to the target, and depending on the environment, various actions can be executed. These actions include: * Reading files from the operating system * Crashing the thread handling the parsing or causing it to enter an infinite loop * Executing HTTP requests * Loading additional DTDs or XML files * Under certain conditions, executing OS commands

Summary		(es) Cuando se lee el XML de los códigos en el PDF y se analiza utilizando un DocumentBuilder, la configuración predeterminada de DocumentBuilder permite un ataque XXE (XML External Entity). Puede encontrar más información sobre esto en el sitio web del Proyecto de seguridad de aplicaciones abierto a nivel mundial (OWASP). En teoría, un atacante podría aprovechar esto entregando un archivo PDF manipulado al objetivo y, según el entorno, se pueden ejecutar varias acciones. Estas acciones incluyen: * Leer archivos del sistema operativo * Bloquear el hilo que maneja el análisis o hacer que entre en un bucle infinito * Ejecutar solicitudes HTTP * Cargar archivos DTD o XML adicionales * Bajo ciertas condiciones, ejecutar comandos del sistema operativo
