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: 9.8


An antimalware application installed on the remote host is affected by a remote code execution vulnerability.


The Malware Protection Engine version of Forefront Endpoint Protection installed on the remote Windows host is prior to 1.1.17600.5. It is, therefore, affected by an unspecified remote code execution vulnerability. An authenticated, local attacker can exploit this to bypass authentication and execute arbitrary code with administrator privileges.
