Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
This vulnerability exists in the Syrotech SY-GPON-2010-WADONT router due to improper access control in its FTP service. A remote attacker could exploit this vulnerability by establishing an FTP connection using default credentials, potentially gaining unauthorized access to configuration files, user credentials, or other sensitive information stored on the targeted device.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The Syrotech SY-GPON-2010-WADONT router contains an improper access control vulnerability in its FTP service that allows remote attackers to authenticate using default credentials and access sensitive device configuration files, user credentials, and other confidential data stored on the targeted device.

MitigationImmediately change default credentials on the device, disable the FTP service if unnecessary, and restrict network access to the FTP port. If available, apply vendor firmware updates that address credential management and access control.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm device model
    Log into the router admin interface or physically inspect the device label to verify the exact model is Syrotech SY-GPON-2010-WADONT
    Affected if Device model is Syrotech SY-GPON-2010-WADONT
  2. Verify FTP service is enabled
    Access router web interface and check under Network or Services settings for FTP server status, or run a port scan targeting port 21 on the device
    Affected if FTP service is enabled and port 21 is open/listening on the device
  3. Test default FTP credentials
    Attempt FTP connection using common default credentials (such as admin/admin, admin/password, root/root) or verify through router admin panel that credentials have been changed from factory defaults
    Affected if Default credentials remain unchanged or FTP accepts any common default username/password combination
  4. Check FTP network exposure
    Review router firewall settings, WAN access controls, and any port forwarding rules to determine if FTP port 21 is accessible from external networks
    Affected if FTP service is exposed to WAN/internet or accessible from untrusted networks

Device is affected if it is a Syrotech SY-GPON-2010-WADONT router with FTP service enabled and default credentials still active, regardless of network exposure
