A very serious security flaw in all its versions Internet Explorer allows attackers to steal user credentials or conduct phishing attacks through any web page.
Vulnerability, affecting even its fully updated versions Internet Explorer 11 running on Windows 7 and 8,1, was revealed by security researcher David Leo of security firm Deusen. The researcher has publish the technique in detail which allows a hacker to bypass Internet Explorer's Same-Origin Policy (a fundamental element of web applications) which allows cross-site forgeries and the execution of scripts with malicious content on websites.
Vulnerability is a cross-site scripting (XSS). In other words, an attacker is able to run content scripts and inject code on a web page. One integrated PoC published by Leo proves the error via a website Daily Mail.
With the XSS flaw, the security researcher was able to modify the content of the site externally, and due to the severity of the vulnerability, it could also be used to steal the content of the website, such as cookies ID cardς ή στοιχεία σύνδεσης εισόδου από κάποιον χρήστη κατά τη διάρκεια της περιήγησης του.
Changes to HTML and theft of cookies by a hacker could be used for phishing campaigns even on trusted sites.
According to the researcher, the vulnerability was reported to Microsoft on 13 in October of 2014.
Microsoft technicians have been trying to repair the security gap since then.
If you use IE it would be good to change your browser, at least until the vulnerability has been fixed.
