Descriptions

A CWE-611: Improper Restriction of XML External Entity Reference vulnerability exists that could result in information disclosure when opening a malicious solution file provided by an attacker with SCADAPack Workbench. This could be exploited to pass data from local files to a remote system controlled by an attacker. Affected Product: SCADAPack Workbench (6.6.8a and prior)

Una CWE-611: Se presenta una vulnerabilidad de Restricción Inapropiada de la referencia de tipo XML External Entity que podría resultar en una divulgación de información cuando es abierto un archivo de solución malicioso proporcionado por un atacante con SCADAPack Workbench. Esto podría ser explotado para pasar datos de archivos locales a un sistema remoto controlado por un atacante. Producto afectado: SCADAPack Workbench (versiones 6.6.8a y anteriores)

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Schneider Electric SCADAPack Workbench. 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 processing of isasln 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.
