Description

CVE-2017-4028
Craft a Maliciously Misconfigured Registry vulnerability in Microsoft Windows such that McAfee Windows products may allow an administrator to inject arbitrary code into a debugged McAfee process via manipulation of Registry parameters.

The issue was reported against Consumer Windows System Security Suites – AVP, MIS, and MTP. This vulnerability allows an attacker with Windows Administrative privileges to change a registry value such that attacker code can be injected into any Windows process.

NOTE: A successful exploitation is possible only after an adversary gains Administrative privileges on the system. Please see "Technical McAfee Detail on DoubleAgent" at: https://securingtomorrow.mcafee.com/business/update-technical-mcafee-detail-doubleagent/.

Frequently Asked Questions (FAQs)

How do I know whether my McAfee product is vulnerable or not?
For Endpoint products:
Use the following instructions for endpoint or client based products:
  1. Right-click on the McAfee tray shield icon on the Windows task bar.
  2. Select Open Console.
  3. In the console, select Action Menu.
  4. In the Action Menu, select Product Details. The product version is displayed.
What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council’s effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, please visit the CVSS website at: http://www.first.org/cvss/.

When calculating CVSS scores, McAfee has adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We do not factor into a score any potential follow-on exploits that might be made possible by successful exploitation of the issue being scored
 
What are the CVSS scoring metrics that have been used?
