CVE-2022-27611Network attack vector

Authenticated arbitrary-file deletion via path traversal

Published Jul 28, 2022 · Updated Sep 16, 2024

Path traversal in Synology Audio Station before 6.5.4-3367 allows remote authenticated users to delete arbitrary files through webapi. The webapi component fails to confine an attacker-controlled pathname to an intended directory, but Synology has not disclosed the affected endpoint or parameter. A valid account is required, and deletion can alter data or interrupt dependent services; no file-reading impact is reported.
