CVE-2022-22995Network attack vector

Unauthenticated code execution via SMB-AFP file write

Published Mar 25, 2022 · Updated Nov 3, 2025

Netatalk in Western Digital My Cloud OS 5 before 5.19.117 and My Cloud Home before 7.16-220 allows remote attackers to execute code. Default SMB and AFP services expose link-following primitives that can be chained to write attacker-controlled files to arbitrary paths. No authentication or user interaction is required, and successful placement of executable content grants code execution on the appliance.
