Inductive Automation Ignition SimpleXMLReader XML External Entity Processing Information Disclosure Vulnerability.
Does this matter?
Lower severity and a low EPSS score (1.32%). Track it; it rarely justifies an emergency change on its own.
Description
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.
