The end result is added to the page by means of jQuery.append(), a function that will parse HTML code and insert the result into the DOM.

This takes a query parameter, massages it slightly (function getURI() merely removes the query/anchor part from a URL) and then inserts it into a localization string. get ( "url" ) const uri = getURI ( url ) const text = localeData ( `site_report_main_url_ $ ` ]) $ ( "#site_report_main_url" ). The following code has been paraphrased to make it more readable:Ĭonst url = new URLSearchParams ( window.

And the way it handles the url query parameter is clearly problematic. This page happens to be listed in the extensions web accessible resources, meaning that any website can open it with any parameters. Here is what this site report looks like for the test website : It contains a “View site report” link which brings you to the detailed information about the site. When McAfee WebAdvisor prevents you from accessing a malicious page, a placeholder page is displayed instead. It should still be possible for malware running with user’s privileges to gain administrator access through it however. The browser extensions no longer seem to have the capability to add whitelist entries here which gives it some protection for now. From the look of it, the XSS vulnerability in the WebAdvisor application remains unaddressed.

The attack could be performed by any website and the required user interaction would be two clicks anywhere on the page.Īt the time of writing, McAfee closed the XSS vulnerability in the WebAdvisor browser extensions and users should update to version 8.3 (Chrome) or 8.7 (Firefox) ASAP. The latter can then be used to run any commands with privileges of the local system’s administrator.

In the end, a potential attacker could go from a reflective XSS vulnerability in the extension to a persistent XSS vulnerability in the application to writing arbitrary Windows registry values. This choice of technology proved quite fatal: not only did it contribute to both components being vulnerable to XSS, it also made the vulnerability exploitable in the browser extension where existing security mechanisms would normally make exploitation very difficult to say the least. Just push through their scare tactics when it informs you that you will no longer be protected.Both the McAfee WebAdvisor browser extension and the HTML-based user interface of its UIHost.exe application use the jQuery library. You shouldn’t have any trouble getting rid of it. It’s as simple as uninstalling the program the normal way, through Programs and Features in the Control Panel (or Add/Remove Programs for Windows XP). Do yourself a favor and keep your computer clean. As long as you have a good antivirus running and your firewall is enabled, you’re mostly fine, regardless of whatever marketing-speak they throw at you when you try to uninstall it. Windows has all the same alerts already built in. Should I Uninstall McAfee Security Scan?Īs much as I despise products like McAfee Security Scan, I can’t tell you it’s bad for your computer. Really, it’s just a form of advertising, and a very effective one I’d guess.

It’s a halfhearted pseudo-security solution that’s used as an excuse to put McAfee products in front of your eyes. It won’t even remove any malware should it find any. It’s not antivirus, nor does it really protect your computer from anything. McAfee Security Scan is what we in the know like to call “bloatware” or “junkware” or “crapware” or any other number of technical-sounding terms. Windows performs most of these functions already, but McAfee Security Scan makes these alerts more prominent. It checks the status of your firewall, antivirus, and scans your web history and objects currently running in memory for malware. It’s official purpose is to “analyze” your defenses and tell you if your computer is vulnerable. You should read every window before clicking the Next button so that stuff like this doesn’t happen.

The problem is, most people don’t read what the instructions say when they install a program and just click Next until the program is installed. When you install one of these programs that has McAfee Security Scan included, it gives you the ability to opt out. Programs like Java and Adobe Flashplayer frequently come with extra “bloatware” like McAfee Security Scan because they typically get paid nicely for it.

Most likely it came bundled with other software you installed. You probably didn’t install it on purpose. So who did put it on there and why do they think you need it? How Did McAfee Security Scan Get On My Computer? Chances are that you’ve had this installed on your computer once or twice and wondered where in the world-wide-web it came from.
