For [3] (exploiting IE's XSS filter default behaviour to create XSS) see also https://www.slideshare.net/codeblue_jp/xss-attacks-exploitin... . The author recommends either changing the default behaviour to block or disabling the filter altogether. I believe experience has shown this protection method cannot be fixed. Ultimately, safe code is code that can be reasoned about but there never was even any specification for this 'feature'. By comparison, CSP has a strict specification. It covers more attacks, and has a better failure mode between XSS protections' filter and block entire page load behaviours. |
