JAW: Studying Client-side CSRF with Hybrid Property Graphs and Declarative Traversals Soheil Khodayari Giancarlo Pellegrino CISPA Helmholtz Center CISPA Helmholtz Center for Information Security for Information Security Abstract ior and avoiding the inclusion of HTTP cookies in cross-site Client-side CSRF is a new type of CSRF vulnerability requests (see, e.g., [28, 29]). In the client-side CSRF, the vul- where the adversary can trick the client-side JavaScript pro- nerable component is the JavaScript program instead, which gram to send a forged HTTP request to a vulnerable target site allows an attacker to generate arbitrary requests by modifying by modifying the program’s input parameters. We have little- the input parameters of the JavaScript program. As opposed to-no knowledge of this new vulnerability, and exploratory to the traditional CSRF, existing anti-CSRF countermeasures security evaluations of JavaScript-based web applications are (see, e.g., [28, 29, 34]) are not sufficient to protect web appli- impeded by the scarcity of reliable and scalable testing tech- cations from client-side CSRF attacks. niques.
