Descriptions

Rockwell Automation Logix Designer Studio 5000 Versions 32.00, 32.01, and 32.02 vulnerable to an xml external entity (XXE) vulnerability, which may allow an attacker to view hostnames or other resources from the program.

Rockwell Automation Logix Designer Studio 5000 Versiones 32.00, 32.01 y 32.02, es susceptible a una vulnerabilidad de tipo xml external entity (XXE), que puede permitir a un atacante visualizar nombres de host u otros recursos del programa

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Rockwell Automation Studio 5000. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the parsing of AML files. Due to the improper restriction of XML External Entity (XXE) references, a specially 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.
