What is CVE-2020-15419?

A vulnerability exists in the Veeam ONE software that allows remote attackers to disclose sensitive information without requiring authentication. The flaw is located in the Reporter_ImportLicense class, where improper handling of XML External Entity (XXE) references permits an attacker to parse a specially crafted document pointing to a URI. This results in the XML parser accessing the specified URI and potentially embedding confidential file contents back into the XML document. Consequently, an attacker can exploit this flaw to gain unauthorized access to system-level file contents.
