Descriptions
A vulnerability has been identified in Solid Edge SE2020 (All Versions < SE2020MP13), Solid Edge SE2021 (All Versions < SE2021MP3). When opening a specially crafted SEECTCXML 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-11923)
Se ha identificado una vulnerabilidad en Solid Edge SE2020 (Todas las versiones anteriores a SE2020MP13), Solid Edge SE2021 (Todas las versiones anteriores a SE2021MP3). Cuando se abre un archivo SEECTCXML especialmente diseñado, la aplicación podría divulgar archivos arbitrarios a atacantes remotos. Esto es debido al paso de contenido especialmente diseñado hacia el analizador XML subyacente sin tomar las restricciones apropiadas, como prohibir un dtd externo. (ZDI?CAN?11923)
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Siemens Solid Edge Viewer. 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 SEECTCXML 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.
