Day 30 comes with two resources related to weak cryptography to open redirect and RCE examples for beginners!
Weak Cryptography to Open redirect
From Rajesh Ranjan. Yesterday, I shared a writeup about weak cryptography to account takeover. Today I came with another writeup in which there was a weak cryptography, in which
redirect= parameter was vulnerable to open redirect. Do check out this writeup here
