A New Era of SSRF - Exploiting URL Parser in Trending Programming Languages!

We propose a new exploit technique that brings a whole-new attack surface to bypass SSRF (Server Side Request Forgery) protections. This is a very general attack approach, in which we used in combination with our own fuzzing tool to discover many 0days in built-in libraries of very widely-used programming languages, including Python, PHP, Perl, Ruby, Java, JavaScript, Wget and cURL.
