What is CVE-2020-8547?

In phpList version 3.5.0, a vulnerability exists that allows for admin login bypass due to improper comparison of password hashes. The use of '==' for password verification instead of '===' introduces type juggling issues, particularly affecting hashes that begin with '0e' followed by numerical characters. This flaw could potentially enable unauthorized users to access the admin panel without valid credentials.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
