🦑Critical Security Bug in Meta Ecosystem – Zero-Click Account Takeover 🔒

As cybersecurity researchers, my buddy Musawer Khan and I uncovered a Zero-Click Account Takeover (ATO) vulnerability in Meta's ecosystem. This vulnerability involved chaining two endpoints—one being a password reset URL that was indexed on platforms like URLScan and Wayback Machine. These URLs should ideally expire after a reasonable timeframe, yet they remained active and exploitable.

Impact:
1. Without requiring any user interaction (zero-click), we were able to gain unauthorized access to multiple accounts by chaining an endpoint and a password reset link.
2. This demonstrates a serious flaw in how reset links are managed, as they should expire promptly to mitigate potential misuse.

Despite providing a detailed proof-of-concept (PoC) showcasing the exploit, Meta Meta Facebook security team declined to classify this as a vulnerability under their bug bounty program, stating that the URLs were publicly exposed before indexing. However, the persistence of these sensitive URLs and the ability to exploit them points to a systemic issue.

Our Responsibility:
As responsible researchers, Musawer Khan and I ensured that all live URLs were expired from our side before disclosing the findings publicly. Our goal is to raise awareness about the importance of securing password reset mechanisms and ensuring that sensitive URLs are time-bound and properly invalidated.

Key Takeaways:
Password reset URLs should automatically expire after a short duration or after first use.
