CVE-2024-4464Network attack vector

Unauthenticated file disclosure via user-controlled authorization key

Published Dec 18, 2024 · Updated Dec 18, 2024

Authorization bypass in Synology Media Server before 1.4-2680, 2.0.5-3152, and 2.2.0-3325 allows remote attackers to read specific files. The streaming service trusts a user-controlled key for authorization, but Synology has not disclosed the affected request or validation logic. No authentication or user interaction is required; the demonstrated consequence is limited to disclosure of specific files.
