## Summary

Sophos UTM (all versions) is affected by a flaw that lets a remote attacker who does not need to log in run arbitrary code with root privileges, giving them full control of the device. The attack can be carried out when the email proxy with scanning is enabled, and the product is end-of-life, so the fix must be applied manually.
