Descriptions

Apache PDFBox before 1.8.12 and 2.x before 2.0.1 does not properly initialize the XML parsers, which allows context-dependent attackers to conduct XML External Entity (XXE) attacks via a crafted PDF.

Apache PDFBox en versiones anteriores a 1.8.12 y 2.x en versiones anteriores a 2.0.1 no inicializa correctamente los analizadores XML, lo que permite a atacantes dependientes del contexto llevar a cabo ataques XML External Entity (XXE) a través de un PDF manipulado.

It was found that the parsing of XMP and other XML formats in PDF by Apache PDFBox would expand entity references. A remote, unauthenticated attacker could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XXE attacks.
