CVE-2025-10957Network attack vector

Sensitive-file access via default FTP credentials

Published Sep 25, 2025 · Updated Sep 25, 2025

Improper access control in Syrotech SY-GPON-2010-WADONT V2.1.05-210329 allows remote attackers to access sensitive files over FTP. The router's FTP service accepts vendor-default credentials and exposes configuration files, stored user credentials, and other device data without device-specific authorization. Network reachability to FTP and knowledge of the default credentials are required; public sources do not describe permitted write operations or a concrete availability effect.
