CVE-2017-20210Network attack vector

Unauthenticated remote code execution

Published Nov 11, 2025 · Updated Nov 11, 2025

Remote code execution in QNAP Photo Station 5.4.x before 5.4.1 and 5.2.x before 5.2.7 allows remote attackers to run arbitrary code. QNAP links the flaw to XMR mining programs but has not disclosed the affected code locus or the wrong operation performed on untrusted input. No authentication or user interaction is required, and successful exploitation grants code execution that can install mining software and disrupt NAS workloads.
