Original Post: From Reset to Takeover: The Exploitation Potential of IDOR in Password Recovery Systems | by Tusharpuri | Aug, 2024
The content discusses a cybersecurity professional’s experience with penetration testing, particularly focusing on authentication mechanisms. Initially, the author examines the login process for common weaknesses without finding significant flaws. The major vulnerability is discovered in the "Forgot Password" functionality where an Insecure Direct Object Reference (IDOR) allows unauthorized users to change another user’s password. By modifying the email parameter, the author successfully resets a target account’s password. Furthermore, a lack of rate limiting on OTP (one-time password) verification enables a brute force attack to bypass Multi-Factor Authentication (MFA), leading to full account takeover.
The combined vulnerabilities emphasize the need for layered security in authentication processes, showcasing how individual flaws can together create severe security risks. The article concludes by highlighting the importance of thorough testing and vigilance in cybersecurity to protect user accounts.
