CVE-2024-53285Network attack vector

File access and service interruption via DDNS XSS

Published Dec 9, 2024 · Updated Aug 1, 2025

Cross-site scripting in Synology Router Manager before 1.3.1-9346-10 allows remote authenticated users to access files and interrupt service. The DDNS Record functionality fails to neutralize attacker-controlled input before web-page generation, allowing injected script or HTML to execute. Administrator privileges and user interaction are required; successful exploitation is limited to reading or writing specific non-sensitive files and limited denial of service.
