In this talk, we present the experimental experience in the evaluation of ProbetheProto (NDSS’22), the first large-scale measurement study of client-side prototype pollution vulnerabilities. First, we discuss the challenges for deploying ProbetheProto on real-world websites and how we mitigate them in the deployment. We present a breakdown of real-world consequences and defenses found by ProbetheProto. Second, we describe how we compare ProbetheProto with a state-of-the-art detection tool. Specifically, we modify ObjLupAnsys, a Node.js prototype pollution detection tool, to support client-side applications. Results show that ProbetheProto significantly outperforms ObjLupAnsys in two experimental settings. Lastly, we experimentally evaluate the code coverage, the performance overhead, and the True Positive Rate (TPR) of ProbetheProto. We will also discuss our evaluation limitations.
