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 is different from CVSS.

VPR Score: 3.6

Synopsis

The Microsoft .NET Framework installation on the remote host is missing a security update.

Description

The Microsoft .NET Framework installation on the remote host is missing a security update. It is, therefore, affected by an elevation of privilege vulnerability, which exists when the .NET Framework common language runtime (CLR) allows file creation in arbitrary locations. An attacker who successfully exploited this vulnerability could write files to folders that require higher privileges than what the attacker already has.

Solution

Microsoft has released security updates for Microsoft .NET Framework.
