Nytro Posted November 15, 2020 Report Posted November 15, 2020 Parameter pollution is a very old attack however I feel like it is under rated. 20+ JS libraries were vulnerable to this attack including JQuery. This is an important attack to learn for any web application pentester. There are few automated tools which are able to detect this however, it does require manual inspection.
