The attack is made possible due to insufficient filtering of variables in the HTTP request (the field HTTP_USER_AGENT, HTTP_X_FORWARDED_FOR, REMOTE_ADDR) and their subsequent use in the session object, and query a database.

The company Mozilla, which is the developer of the browser Firefox, in his blog said phaseout of support with sites using a secure protocol is not HTTP. In the first place not on a secure site will not work all the new functions of the browser, as well as those functions that browser developers deem dangerous.

This is due to the fact that the HTTP protocol is outdated in terms of security and the entire transmitted between the user and site information can easily be intercepted and read by third parties.
