Summary
A path traversal vulnerability allows a remote unauthenticated attacker to execute arbitrary code as root in Sophos UTM (all versions) after winning a race condition by sustaining repeated attacks for a few minutes when the email proxy is used with scanning enabled. Sophos UTM is end-of-life and the patch must be installed manually.
Severity
8.1 (High)
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
