Hacking Unicode Like a Boss
Blog post from Bugcrowd
The text discusses a Unicode vulnerability discovered by Wisdom in GitHub's password reset system. The vulnerability allows an attacker to trigger a password reset email to be delivered to the wrong email address due to incorrect handling of Unicode characters. A lab has been created for researchers to practice exploitation against this vulnerability, and it is essential to understand Unicode to identify and fix such issues. The vulnerability can be fixed by converting emails to ASCII or using the email address from the database instead of the user-provided one. This highlights the importance of understanding character encoding and its potential vulnerabilities in software.
