内容摘要:
围绕内存漏洞的攻防已经持续了近三十年。随着防护技术的发展,针对控制流的攻击变得愈发困难。少量针对数据流的攻击显示出了其潜在的危害性。 然而,目前对针对数据流的攻击还知之甚少。 我们深入地研究了针对数据流的攻击,提出了系统性的构造方法,并证明其危害性为图灵完备的。最后我们在主流浏览器 Chromium 上实现了针对数据流的攻击,成功绕过了同源策略。
As defense solutions against control-flow hijacking attacks gain wide deployment, control-oriented exploits from memory errors become difficult. As an alternative, attacks targeting non-control data do not require diverting the application’s control flow during an attack. Although it is known that such data-oriented attacks can mount significant damage, we are not clear about their real expressiveness. In this talk, we present data-flow stitching, a systematic method to build data-oriented attacks. Then we propose data-oriented programming to demonstrate that data-oriented attacks can be Turing-complete. Finally, we build data-oriented attacks on Chromium to bypass the fundamental SOP (same origin policy) enforcement.
