Security readout for executives and security teams
Plain-English summary
CVE-2018-25036 is a low-severity stored cross-site scripting issue in Thomson TCW710 router firmware. A user with low privileges can save script content in time server settings, and a later viewer of the affected page may run it in their browser. Business urgency is limited unless these devices are still deployed or exposed for remote administration.
Executive priority
Treat as a low-priority exposure cleanup item, not an emergency. Prioritize if TCW710 routers remain in production, support remote administration, or sit in sensitive network segments.
Technical view
The CVE describes persistent XSS in Thomson TCW710 ST5D.10.05, affecting /goform/RgTime through TimeServer1, TimeServer2, and TimeServer3 POST parameters. It is mapped to CWE-80 with CVSS 3.1 score 3.5: AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N.
Likely exposure
Exposure appears limited to Thomson TCW710 devices running firmware ST5D.10.05. The sources do not provide deployment prevalence, patch status, or affected CPEs. Risk increases if the router management interface is reachable beyond trusted administrator networks.
Exploitation context
The source bundle says exploit details were publicly disclosed and may be used. It is not listed in CISA KEV, and no cited source establishes active exploitation. CVSS indicates network reachability, low privileges, and required user interaction.
Researcher notes
Evidence is sparse. The CVE identifies parameters and endpoint, but the bundle does not name a fixed version or vendor mitigation. Avoid assuming broader Thomson models are affected without vendor confirmation.
Mitigation direction
- Inventory Thomson TCW710 devices and confirm firmware version ST5D.10.05.
- Restrict router management access to trusted administrator networks or VPN.
- Check Thomson, ISP, or device-owner guidance for firmware updates or replacement.
- Review stored time server settings for unexpected script content.
- Retire unsupported exposed devices where no vendor fix is available.
Validation and detection
- Confirm whether any TCW710 devices run firmware ST5D.10.05.
- Verify management interfaces are not exposed to untrusted networks.
- Review router configuration fields for unexpected stored markup or script content.
- Check logs or admin history for suspicious time settings changes.
- Track vendor or ISP advisories for confirmed remediation guidance.
