Inductive Automation Ignition SimpleXMLReader XML External Entity Processing Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Inductive Automation Ignition. Authentication is required to exploit this vulnerability. The specific flaw exists within the SimpleXMLReader class. 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 SYSTEM. . Was ZDI-CAN-17571.

Summary
  • (es) Vulnerabilidad de divulgación de información de procesamiento de entidades externas XML de SimpleXMLReader de encendido de automatización inductiva. Esta vulnerabilidad permite a atacantes remotos revelar información confidencial sobre las instalaciones afectadas de Inductive Automation Ignition. Se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe dentro de la clase SimpleXMLReader. Debido a la restricción inadecuada de las referencias a entidades externas XML (XXE), un documento elaborado que especifica un URI hace que el analizador XML acceda al URI e incruste el contenido nuevamente en el documento XML para su posterior procesamiento. Un atacante puede aprovechar esta vulnerabilidad para revelar información en el contexto del SISTEMA. Era ZDI-CAN-17571.
