Avast SafeZone Browser Lets Attackers Access Your Filesystem (softpedia.com)

An anonymous reader writes: Just two days after Comodo's Chromodo browser was publicly shamed by Google Project Zero security researcher Tavis Ormandy, it's now Avast's turn to be publicly scorned for failing to provide a "secure" browser for its users. Called SafeZone, and also known as Avastium, Avast's custom browser is offered as a bundled download for all who purchase or upgrade to a paid version of Avast Antivirus 2016. This poor excuse of a browser was allowing attackers to access files on the user's filesystem just by clicking on malicious links. The browser wouldn't even have to be opened, and the malicious link could be clicked in "any" browser.

    Finally changed to Avira 2 weeks ago and have been glad I did. Very glad now!

      Good choice for a free tool. The pop-up in the corner is slightly annoying but since it's free... And it has caught several nasty's that snuck in, but also has thrown up a few false positives for PUP's, but only in places where files had been downloaded (not system files etc.). Also another suggestion is ClamWin. It is open source and free. It is a little clunky but works great on obscure Win OS'es like 2003 & 2008 server plus all the Windows Clients from XP to Win 8.1. It also runs on Linux as I also have it on 2 different CentOS 6.x boxes.

      Post by the researcher is quite nice and understandable.
      Basically Avast opens a local port for the purpose of interprocess communication (or RPC to be specific). It listens to properly formatted post requests (that can be easily sent from another page you open) and performs some actions from predefined list. One of those actions allows to launch this weird "safe" browser with an arbitrary url. Since Avast removed some chromium safety feature it allowed launching dev tools with some arbitrary controlling javascript, allowing acces to local files, doing requests using stored cookies etc.
      Other application are generally not affected, because they dont provide this local port, so they cant be remotely launched in an easy way (Avast command list is limited, so you cant launch random stuff).
