CVE-2022-22994

Unauthenticated remote code execution via ConnectivityService HTTP data

Published Jan 28, 2022 · Updated Aug 3, 2024

Insufficient verification of data authenticity in Western Digital My Cloud OS 5 before 5.19.117 allows remote attackers to execute code via HTTP. ConnectivityService accepts HTTP data without proper authentication and executes attacker-supplied behavior in the root context. Exploitation requires network-adjacent access but no authentication or user interaction, with potential compromise of confidentiality, integrity, and availability.
