HTML Sanitizing Bypass - CVE-2012-1858
The toStaticHTML component, which is found in Internet Explorer > 8, SharePoint and Lync is used to sanitize HTML fragments from dynamic and potentially malicious content.
If an attacker is able to break the filtering mechanism and pass malicious code through this function, he/she may be able to perform HTML injection based attacks (i.e. XSS).
It has been a year since the first encounter was published, we've now returned with a new bypass method.
