ctr-httpwn is an exploit for the HTTP system module. It was mainly used to prevent the console from seeing and downloading new system updates, before the advent of easily-accessible custom firmware.
The first version released on March 22, 2016.
Nintendo released 11.4.0-37 on April 10, 2017. The ctr-httpwn application stopped working, but the vulnerability was not actually fixed. An example of the exploit working on 11.4 and later is nimhax.
