What is CVE-2018-9233?

Sophos Endpoint Protection 10.7 employs an unsalted SHA-1 hashing algorithm for storing passwords in the machine.xml configuration file. This insecure method increases the risk of exposure, as attackers can utilize rainbow tables and other tools to easily reverse-engineer the hashed passwords to their cleartext form. Consequently, they can manipulate malware settings adversely, posing significant security dangers to affected systems.

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.
