high Nessus Plugin ID 88648
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: 8.9

Synopsis

The remote host is affected by an elevation of privilege vulnerability.

Description

The remote Windows host is missing a security update. It is, therefore, affected by a flaw in the Microsoft Web Distributed Authoring and Versioning (WebDAV) client due to improper validation of user-supplied input. A local attacker can exploit this, via a specially crafted application, to execute arbitrary code with elevated privileges.

Solution

Microsoft has released a set of patches for Windows Vista, 2008, 7, 2008 R2, 2012, 8.1, RT 8.1, 2012 R2, and 10.
