as a Cross-Site Scripting, or XSS, bug. With Microsoft apparently now investigating and looking at a patch, the timing of the disclosure certainly looks to be irresponsible. There's no suggestion that Microsoft failed to meet http://answers.microsoft.com/en-us/ie/forum/ie9-windows_7/cross-scripting-error-on-websites-internet/50e20a13-bcdf-46b2-b3b2-1771cd56e25b any sort of deadline to get a patch out, or even that the company was contacted in advance. Nevertheless, details of the bug have been revealed, including some proof-of-concept JavaScript showing how to abuse the hole. So, what is XSS, and what does this mean for security? A SOP for security Browser security, as you will have read before on Naked Security, depends heavily on what's called the Same Origin Policy, https://nakedsecurity.sophos.com/2015/02/04/internet-explorer-has-a-cross-site-scripting-zero-day-bug/ or SOP. Simply put, any resources specific to site X that are stored locally by the browser, such as cookies and JavaScript data objects, should only subsequently be visible when you are looking at content from site X. In other words, if you visit my site, example.com, and I set a cookie that says, "This user last searched for the word ‘banana'," only JavaScript from my site should ever be able to read that data back. If your next web page is another.example, then my cookie should essentially vanish from view. But if ever you browse back to a page on the example.com site, the ‘banana' cookie will be visible again. There are two obvious reasons for this: Safety. Two sites might set a cookie with the same name, e.g. UserHasLoggedIn. These are different cookies and must not be allowed to clash. Security. Whether a UserHasLoggedIn or not on my site is no business of yours. So my cookie should be kept private. Enter XSS But what if I can rig up a web link or some JavaScript on my site that fetches a page from your site, and somehow adapts it with malicious content of my choice before the user's browser displays it? If I can somehow injec

From the issue description, I understand that you get internet explorer 11 script errors in Internet Explorer 10. XSS is a feature provided by IE to protect users from cross-site scripting attacks. Cross site scripting (also known as XSS) occurs when a web application gathers malicious data from a user. The data is usually gathered in the form of a hyperlink which contains malicious content within it. The user will most likely click on this link from another website, instant message, or simply just reading a web board or email message. Usually the attacker will encode the malicious portion of the link to the site in HEX (or other encoding methods) so the request is less suspicious looking to the user when clicked on. After the data is collected by the web application, it creates an output page for the user containing the malicious data that was originally sent to it, but in a manner to make it appear as valid content from the website Source Article - Can I disable XSS filter to stop script error in Internet Explorer 10? You may refer to the solutions provided in the above article. However, It is not recommended to turn off the XSS Filter. Doing so will leave you vulnerable to cross-site scripting attacks as explained above. You may allow users to disable XSS filter and alternatively apply methods to prevent your website to prevent from cross-site attacks.

It's described this way: The XSS Filter, a feature new to Internet Explorer 8, detects JavaScript in URL and HTTP POST requests. If JavaScript is detected, the XSS Filter searches evidence of reflection, information that would be returned to the attacking Web site if the attacking request were submitted unchanged. If reflection is detected, the XSS Filter sanitizes the original request so that the additional JavaScript cannot be executed. I'm finding that the XSS filter kicks in even when there's no "evidence of reflection", and am starting to think that the filter simply notices when a request is made to another site and the response contains JavaScript. But even that is hard to verify because the effect seems to come and go. IE has different zones, and just when I think I've reproduced the problem, the filter doesn't kick in anymore, and I don't know why. Anyone have any tips on how to combat this? What is the filter really looking for? Is there any way for a good-guy to POST data to a 3rd-party site which can return HTML to be displayed in an iframe and not trigger the filter? Background: I'm loading a JavaScript library from a 3rd-party site. That JavaScript harvests some data from the current HTML page, and posts it to the 3rd-party site, which responds with some HTML to be displayed in an iframe. To see it in action, visit an AOL Food page and click the "Print" icon just above the story. internet-explorer-8 xss share|improve this question asked Jan 12 '10 at 19:12 Ned Batchelder 178k31338493 Here's a blog entry posted by Microsoft that gives some more details about how the XSS filter works: * IE 8 XSS Filter Architecture / Implementation –Joe Jan 19 '11 at 6:11 add a comment| 3 Answers 3 active oldest votes up vote 53 down vote accepted What does it really do?
