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.
