Fixes Released (and More Promised) For "Clickjacking" Exploits

An anonymous reader writes "As discussed previously on Slashdot, concern has been raised over a class of 'clickjacking' vulnerabilities which affect all major Web browsers. These exploits allow an attacker to place invisible or seemingly legit objects on a Web page that perform undesired actions when a user clicks on them. In recent developments, 'Guya' posted a scary proof-of-concept that hijacks Adobe Flash Player to spy on users with a webcam and/or microphone. In response, Adobe released an advisory with a temporary workaround, and stated that a future Player update will address the exploit. This prompted the original disclosers of the vulnerabilities to post a summary of the exploits. Additionally, Giorgio Maone, creator of the popular NoScript extension for Firefox and other Gecko-based browsers, released version 1.8.2.1 of NoScript, which adds 'ClearClick,' a feature that intercepts clicks made on invisible or otherwise obscured elements on a page. Although issues remain, there seems to be progress in addressing these security problems."

Well, an example is the "Get Add-on" link on the NoScript website: clicking it causes an iframed link from Mozilla's add-on page to be "clicked" instead.

Clickjacking's new in terminology only.

I was describing this article to my boss, and here is what he said to me verbatim. My Emp. added.

So, should I be afraid of my web browser clickjacking me off of my normally visited websites to some spyware?

NoScript

[HTH NE1]

Now if only NoScript, when I choose (for example) "Temporarily allow doubleclick.net", granted that allowance only on the page I'm viewing and its descendants and not in every open tab in every window to every site their scripts are on!

Re:NoScript

[kesuki]

apparently, feature suggestions should be posted to this forum http://forums.mozillazine.org/viewtopic.php?t=826005

'temporarily allow site in tab' and 'temporarily allow all in tab' are features i'd suggest, but i'm too lazy to sign up for a forum and post there.

being specific to a single tab would be nice, it might add to the size of the engine, but again it would make annoying broken ad supported sites like pogo that require 26 separate sites to be 'allow' to properly load a webgame... no, i don't play pogo, but i disabled noscript from one of my parents computers so she could use pogo. I checked to see if i could just add to the white list, but that basically defeated the point of a white list, so it was disabled.

on windows it's no big deal, she uses ie, and i use firefox, but on their linux system, which she rarely uses, except when there are issues with the other computer... well, it has to stay set so she can play pogo on it if needed.

Any form of invisible link, invisible button, link or button in an iframe, getURL() call in Flash, or JavaScript handler for any normally non-clickable item that makes you go somewhere, yeah.

Re:Flash and microphones and webcams, oh my.

It's always kind of creeped me out that Flash even gives applets access to the microphone

Definitely creepy. One time I visited a page with a Flash-based advertisement from (apparently) a French company. When my mouse cursor inadvertently moved over the Flash applet, some kind of contact was made with the company. This French guy was screaming into his microphone "'ello?? 'ELLOO??". And he obviously saw through my cam because he continued: "Bonjour, sire! Whas arr yous eatingue?" just when I was shoving a sandwhich in my pie-hole.
