25.12.2020  How to bypass mod_security (WAF)

Hello, this time I would like to share with you how to evade the WAF mod_security.

Looking for vulnerable pages I came across a website that, after spending a little time on it, I realized that it could be vulnerable to sql injections, then I realized that it was “protected” with mod_security and decided to see if I could skip the waf.

I share how I did it …
