Sophos Endpoint Protection 10.7 uses an unsalted SHA-1 hash for password storage in %PROGRAMDATA%\Sophos\Sophos Anti-Virus\Config\machine.xml, which makes it easier for attackers to determine a cleartext password, and subsequently choose unsafe malware settings, via rainbow tables or other approaches.

Sophos Endpoint Protection 10.7 allows local users to bypass an intended tamper protection mechanism by deleting the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Sophos Endpoint Defense\ registry key.
