Security readout for executives and security teams
Plain-English summary
CVE-2018-25037 is a stored cross-site scripting issue in the Thomson TCW710 router firmware ST5D.10.05. A low-privileged authenticated user could save malicious content in the DDNS hostname field that later runs in another user’s browser. Business risk is mainly admin-session abuse or configuration tampering, not direct device takeover.
Executive priority
Treat this as low severity but worth closing during router hygiene work. Priority rises if affected routers are internet-administered, shared with semi-trusted users, or unsupported by the vendor or ISP.
Technical view
The issue affects /goform/RgDdns on Thomson TCW710 ST5D.10.05. The DdnsHostName POST parameter is not safely handled, allowing persistent XSS. CVSS 3.1 is 3.5: network reachable, low attack complexity, low privileges required, user interaction required, integrity impact only. CWE mapping is CWE-80.
Likely exposure
Exposure is likely limited to organizations still operating Thomson TCW710 devices on firmware ST5D.10.05, especially where router administration is reachable by untrusted users or networks.
Exploitation context
Public disclosure and exploit availability are reported in the source bundle, but CISA KEV is false and no provided source confirms active exploitation in the wild.
Researcher notes
Evidence names one product and firmware version only: Thomson TCW710 ST5D.10.05. The reported sink is persistent XSS through DdnsHostName in /goform/RgDdns. Sources do not provide a vendor patch, broad version range, or confirmed active exploitation.
Mitigation direction
- Inventory Thomson TCW710 devices and confirm firmware version ST5D.10.05.
- Check vendor or ISP guidance for supported firmware or replacement options.
- Restrict router administration to trusted networks and authorized administrators.
- Review DDNS settings for unexpected stored markup or script-like content.
- Retire or replace unsupported affected devices where no vendor fix is available.
Validation and detection
- Confirm whether any TCW710 devices run firmware ST5D.10.05.
- Verify the DDNS management route is not exposed to untrusted networks.
- Review DDNS hostname values for suspicious stored content.
- After remediation, verify stored DDNS values render as escaped text.
- Confirm only authorized administrators can modify DDNS settings.
