CVE-2018-25038: Thomson TCW710 RgDhcp Persistent cross site scriting

A vulnerability was found in Thomson TCW710 ST5D.10.05. It has been classified as problematic. This affects an unknown part of the file /goform/RgDhcp. The manipulation of the argument PppUserName with the input ><script>alert(1)</script> as part of POST Request leads to cross site scripting (Persistent). It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.

Security readout for executives and security teams

Plain-English summary

This issue lets an authenticated attacker store malicious web content in a Thomson TCW710 router setting. A later user viewing the affected administration page could have browser-side actions altered. The business impact is limited by required access and user interaction, but exposed or shared router admin access raises concern.

Executive priority

Handle during normal vulnerability management unless the admin interface is exposed externally or widely shared. Prioritize removing public management access and confirming whether affected legacy routers remain in service.

Technical view

CVE-2018-25038 is a persistent cross-site scripting issue in Thomson TCW710 firmware ST5D.10.05, affecting /goform/RgDhcp through the PppUserName argument in a POST request. CVSS 3.1 is 3.5 low: network reachable, low complexity, privileges required, user interaction required, integrity impact only.

Likely exposure

Exposure appears limited to Thomson TCW710 devices running ST5D.10.05 where an attacker can authenticate to the router interface and persuade or wait for another user to view the stored value. Public internet exposure of the admin interface would increase practical risk.

Exploitation context

The source bundle says a public exploit has been disclosed and may be used. It does not show CISA KEV listing or other evidence of active exploitation. Treat this as publicly known, not confirmed exploited in the wild.

Researcher notes

Evidence names the affected file and parameter, but says the affected code part is unknown. No patch or fixed firmware is provided in the supplied sources, so remediation should be anchored to vendor or provider guidance rather than assumed fixes.

Mitigation direction

  • Identify Thomson TCW710 devices and confirm firmware version ST5D.10.05 exposure.
  • Restrict router administration access to trusted management networks only.
  • Review vendor or service-provider guidance for firmware updates or replacement advice.
  • Limit shared or low-privilege administrator accounts where possible.
  • Rotate credentials if suspicious configuration changes are found.

Validation and detection

  • Inventory network edge and customer-premises devices for Thomson TCW710 ST5D.10.05.
  • Confirm the router administration interface is not internet-accessible.
  • Review configuration fields for unexpected markup or unauthorized changes.
  • Check router logs or change history for suspicious DHCP or PPP setting updates.
