We explore this vulnerability pattern. First, we give an analysis of the root causes and document existing attack vectors. Then we take steps to assess the current attack surface of Session Fixation. Finally, we present a transparent server-side method for mitigating vulnerabilities.enText/Conference Paper1617-5468
