CVE-2023-40507

LG Simple Editor copyContent XML External Entity Processing Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of LG Simple Editor. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the copyContent command. 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 SYSTEM. . Was ZDI-CAN-20006.

Summary		(es) Vulnerabilidad de divulgación de información de procesamiento de entidades externas XML de contenido de copia de LG Simple Editor. Esta vulnerabilidad permite a atacantes remotos revelar información confidencial sobre las instalaciones afectadas de LG Simple Editor. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe en la implementación del comando copyContent. 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 de SYSTEM. Fue ZDI-CAN-20006.
