Descriptions

A vulnerability has been identified in JT2Go (All versions < V13.1.0), Teamcenter Visualization (All versions < V13.1.0). When opening a specially crafted xml file, the application could disclose arbitrary files to remote attackers. This is because of the passing of specially crafted content to the underlying XML parser without taking proper restrictions such as prohibiting an external dtd. (ZDI-CAN-11890)

Se ha identificado una vulnerabilidad en JT2Go (todas las versiones anteriores a V13.1.0), Teamcenter Visualization (todas las versiones anteriores a V13.1.0). Al abrir un archivo xml especialmente diseñado, la aplicación podría revelar archivos arbitrarios a atacantes remotos. Esto es debido al paso de contenido especialmente diseñado al analizador XML subyacente sin tomar las restricciones apropiadas, como prohibir un dtd externo. ZDI-CAN-11890)

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Siemens JT2Go. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of PLMXML files. Due to the improper restriction of XML External Entity (XXE) references, a crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of the current process.
