Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 3.6


The remote Windows host is affected by an information disclosure vulnerability.


The remote Windows host is missing a security update. It is, therefore, affected by an information disclosure vulnerability in .NET Framework due to improper processing of XML input containing a reference to an external entity. An unauthenticated, remote attacker can exploit this, via specially crafted XML data, to read arbitrary files.


Microsoft has released a set of patches for Microsoft .NET Framework 2.0 SP2, 3.5, 3.5.1, 4.5.2, 4.6, and 4.6.1.
