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: 9.7

Synopsis

It may be possible to execute arbitrary code on the remote Windows host using a malicious shortcut file.

Description

Windows Shell does not properly validate the parameters of a shortcut file when loading its icon. Attempting to parse the icon of a specially crafted shortcut file can result in arbitrary code execution. A remote attacker could exploit this by tricking a user into viewing a malicious shortcut file via Windows Explorer, or any other application that parses the shortcut's icon. This can also be exploited by an attacker who tricks a user into inserting removable media containing a malicious shortcut (e.g. CD, USB drive), and AutoPlay is enabled.

EASYHOOKUP is one of multiple Equation Group vulnerabilities and exploits disclosed on 2017/04/14 by a group known as the Shadow Brokers.

Solution

Either apply the MS10-046 patch or disable the displaying of shortcut icons (refer to the Microsoft advisory).
