New! Vulnerability Priority Rating (VPR)

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's different from CVSS.

VPR Score: 9


The remote Windows host has a browser plugin installed that is affected by an arbitrary code execution vulnerability.


The remote Windows host is missing security update KB4580325. It is, therefore, affected by a NULL pointer dereference flaw. An unauthenticated, remote attacker can exploit this, by inserting malicious strings in an HTTP response that is by default delivered over TLS/SSL.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Microsoft has released KB4580325 to address this issue.
