So, should I trust their mediocre programmers for my security? Anyway, if something nasty happens with my online bank account because it's unsafe, i'll sue them to death (or better, i'll let the world know) until they refund. So you may say "trustworthy" means "accountable". Starting with version, noscript offers a " Site Info " page which can help you assess the trustworthiness of any web site shown in your noscript menu. You can access this service by middle-clicking or shift-clicking the relevant menu item. If you're more on the technical side and you want to examine the javascript source code before allowing, you can help yourself with jsview (unofficial). Also, if you seek for assistance in the noscript forum and you want to report the sites listed in your menu, you can easily do it, with no need for typing them, by just right-clicking one item or the menu itself: this will copy the. you may ask, what if site i really trust gets compromised?

Other plugins are harder to exploit, because most of them don't host a virtual machine like java and Flash post do, but they can still expose holes like buffer overruns that may execute arbitrary code when fed with a specially crafted content. Recently we have seen several of these plugin vulnerabilities, affecting Acrobat reader, quicktime, realPlayer and other multimedia helpers. Please notice that none of the aforementioned technologies is usually (95 of the time) affected by publicly known and still unpatched exploitable problems, but the point of noscript is just this: preventing exploitation of even unknown yet security holes, because when they are discovered. 1.11 Q: What is a trusted site? A: A "trusted site" is a site whose owner is well identifiable and reachable, so i have someone to sue if he hosts malicious code which damages or steals my data. If a site qualifies as "trusted there's no reason why i shouldn't allow javascript, java or Flash. If some content is annoying, i can disable it with AdBlock. What I'd like to stress here is that "trust" is not necessarily a technical matter. Many online banking sites require javascript and/or java, even in contexts where these technologies are absolutely useless and abused: for more than 2 years i've been asking my bank to correct a very stupid javascript bug preventing login from working with Firefox. I worked around this bug writing an ad hoc writing bookmarklet, but I'm not sure the average joe user could.

Anyway, the java security model allows signed applets (applets whose integrity and origin are guaranteed by a digital certificate) to run with local privileges,. Just like they were regular installed applications. This, combined with the fact there are always users who, in front of writings a warning like "This applet is signed with a bad/fake certificate. You don't want to execute it! Are you so mad to execute it, instead? Nope no maybe will search, find and hit the "Yes" button, caused some bad reputation even to firefox (notice that the article is quite lame, but as you can imagine had much echo). Flash used to be considered relatively safe, but since its usage became so widespread severe security flaws have been found at higher rate. Flash applets have also been exploited to launch xss attacks against the sites where they're hosted.

To steal important information you store or enter on the web (credit card numbers, email credentials and so on) or to "impersonate" you,. In fake financial transactions, launching "cloud" attacks like cross Site Scripting (XSS) or csrf, with no need for escaping your browser or gaining privileges higher than a normal web page. This alone is enough reason to allow scripting on trusted sites only. Moreover, many security exploits are aimed to achieve a "privilege escalation. Exploiting an implementation error of the sandbox to acquire greater privileges and perform nasty task like installing trojans, rootkits and keyloggers. This kind of attack can target javascript, java, flash and other plugins as well: javascript looks like a very precious tool for bad guys: most of the fixed browser-exploitable vulnerabilities discovered to date were ineffective if javascript was disabled. Maybe the reason is that scripts are easier to test and search for holes, even if you're a newbie hacker: everybody and his brother believe to be a javascript programmer :p java has a better history, at least in its "standard" incarnation, the sun jvm. There have been viruses, instead, written for the microsoft jvm, like the ojan.

Security - potentially vulnerability using setInterval

It usually happens when a master page creates (or statically contains) an empty sub-frame (automatically addressed as about:blank ) and then populates it using scripting. Hence, if the master page is not allowed, no script can be placed inside the about:blank empty page and its "allowed" privileges will be void. Given the above, risks in keeping about:blank allowed should be very low, if any. Moreover, some firefox extensions need it to be allowed for scripting in order to work. Sometimes, especially on partially allowed sites, you may see also a wyciwyg: entry. It stands for "What you cache Is What you get and identifies pages whose content is generated by javascript code through mla functions like document. If you can see such an entry, you already allowed the script generating it, hence the above about:blank trust discussion applies to this situation as well.

1.10 Q: Why should i allow javascript, java, flash and plugin execution only for trusted sites? A: javascript, java and Flash, even being very different technologies, do have one thing in common: they execute easy on your computer code coming from a remote site. All the three implement some kind of sandbox model, limiting the activities remote code can perform:. G., sandboxed code shouldn't read/write your local hard disk nor interact with the underlying operating system or external applications. Even if the sandboxes were bullet proof (not the case, read below) and even if you or your operating system wrap the whole browser with another sandbox (e.g. IE7 on Vista or Sandboxie the mere ability of running sandboxed code inside the browser can be exploited for malicious purposes,.

1.7 Q: have i got to disable javascript from Firefox options to browse safely with noscript? A: you must not disable javascript in Firefox!

A: you don't need to: noscript can block java, flash and other plugins. 1.9 Q: Why can I sometimes see about:blank and/or wyciwyg: entries in my noscript menu? What scripts are causing this?

Write or dom manipulation, for instance) by another script which must have its own permissions to run.
