bcman Posted December 17, 2015 Report Posted December 17, 2015 In this post, I would like to share XSS attack using IE's XSS filter. This issue was fixed in the December patch by Microsoft. (CVE-2015-6144 / CVE-2015-6176)I spoke about this topics in the Japanese info-sec conference called CODE BLUE. You can find my name here. In my presentation, I talked about only the concept and I didn't touch details of attack techniques because it was not fixed at that time. Today, I can finally release hidden slides! Yeah!The real X-XSS-Nightmare slides is the following.MKSB(en): X-XSS-Nightmare: XSS Attacks Exploiting XSS Filter Quote
